<div>== '''General''' ==<br />
The "Thunder" is an unique interface for the Atari TT, which offers the possibility to connect IDE devices to the Atari TT. It is equal, if you use a hard drive, a CD-ROM or a CF card. Usable master / slave IDE to CF adapter or even IDE to SATA adapter can be used. Even SSD devices now works with the Atari TT. The Thunder is a partial plug and play solution. The extension card is plugged onto the TT-RAM socket of the Atari TT (internal slot in front of the power supply, 96-pin connector). It is only necessary to connect the Thunder with just two cables to the mainboard of the TT.<br />
<br />
=== Features ===<br />
<br />
* new development from the year 2016 (Pakman, Tuxie, Gaga)<br />
* IDE interface for the usage with of 1 or 2 IDE devices (master / slave)<br />
* 100% compatible with the Atari Falcon IDE bus<br />
* currently up to 5.75 MB / s transmission rate (tested with CF card)<br />
* special support from the HDDriver from version 10, with which the driver can be loaded into the Fastram and the transmission rate can be accelerated enormously<br />
* Protection of the TT bus against overload caused by buffered data, address and control lines<br />
* compact design, only 7.1 x 9.9 cm, in SMD construction<br />
* central element is a programmable logic block (CPLD) from Xilinx<br />
* looped TT-RAM socket, which allows an expansion, for example the Storm or other TT Fastram cards<br />
* compatible with other Fastram cards, even with those of Atari<br />
* 3 operating modes selectable via jumper block: Falcon compatible (standard) / ByteSwap (ppera) / SmartSwap (PC an Mac compatible)<br />
* also works in accelerated TT, thus further performance increase (tested with 20MHz bus and 40MHz CPU)<br />
<br />
=== Description ===<br />
<br />
On the Thunder, the 96pin FastRAM socket is looped up and a an coded 40pin standard socket for IDE devices.<br />
<br />
The jumper block JP1 - 6 is also located at the bottom left (see jumper assignment).<br />
<br />
The green LED1 signals the operational readiness.<br />
The red LED2 signals accesses to the IDE bus.<br />
<br />
Con4 in the middle as well as the pins GND and + 5V on the upper left are for programming the CPLD - please leave unused and never connect!<br />
<br />
Con3 on the right side connects the two signal lines / Int and XDS1 to the mainboard (see Installation).<br />
<br />
On some Thunder there are small hardware patches; please leave so. As of Rev. C, it is also possible to route the LED2 "outwards".<br />
<br />
[[Bild:Thunderoben.jpg|400px]] [[Bild:Thunder_unten.jpg|400px]]<br />
<br />
=== Revisions and Firmware ===<br />
<br />
As of 15th september 2017 there are 4 Hardwarerevisions of the Thunder, namely Rev. A (prototype), Rev. B (= V 1.0), Rev. C and Rev. D.<br />
The different revisions have the same features and differ only slightly in the structure, but not in the function.<br />
<br />
As of 05th august 2017 the actual firmware for all revisions is: 363.<br />
This firmware is improved in the timing because there are some very few TT, where this current firmware is needed to work.<br />
The firmware used is usually written at the bottom of the Thunder. An update is possible. Thunder with older firmware versions do not need firmware update, if there were so far no problems.<br />
<br />
<br />
<br />
.<br />
<br />
== '''Construction and installation''' ==<br />
<br />
The installation is quite simple:<br />
<br />
<br />
'''1.'''<br />
First, insert the Thunder into the TT-RAM slot. Please pay attention to the correct fit! If necessary, the card can also be firmly fixed to the mainboard with two screws. Please insert the card smoothly, evenly and symmetricaly. The Thunder has for this purpose a special 96pin connector with longer, gilded contacts on the bottom, which are for this kind of application (so called gilded transfer zone). With TT's with Daughterboard or PGA CPU it is sensible to isolate the Thunder downwards for safety reasons, in order to avoid short circuits (see pictures below). A separate power supply of the Thunder is not necessary as this is done via the expansion slot. <br />
<br />
'''2.'''<br />
Two wired connections (signal lines: /INT and /XDS1) are required to use the Thunder. One end of each cable is plugged into Pin2 and Pin3 of Con3 (right side). Pin 1 and pin 4, which are not used, are ground contacts with which the signal lines can be shielded, but regulary it is not necessarily. In principle, the cables should be kept as short as possible. Genuine, pre-assembled and colored cables are included.<br />
<br />
<br />
[[Bild:ThunderMainboardstecker.jpg|200px]]<br />
<br />
<br />
The each other end of the two cables are attached to the following points on the mainboard, best to solder:<br />
<br />
* Cable 1 /INT (Pin2 of the Con3 on the Thunder) goes to pin 10 of the DMA connector or to resistor R311 behind the DMA connector (for TT´s with daughterboard or PGA CPU to the right side of R311)<br />
* Cable 2 /XDS1 (Pin 3 of the Con3 on the Thunder) can be soldered to MFP pin 50 or pin 16 of the row C of the ST-Ram card (front connector)<br />
<br />
<br />
<br />
To prevent the /Int and the /XDS1 lines from being interchanged despite the color code, remenber the following crib:<br />
<br />
On the Thunder the /Int is the "rear/behind" pin - the signal cable also comes "from behind" on the mainboard.<br />
The /XDS1 signal on the Thunder is in "front" - the signal power is also "from the front" on the mainboard.<br />
<br />
<br />
[[Bild:Verlegung.jpg|400px]]<br />
<br />
<br />
<br />
'''3.'''<br />
The Thunder is therefore basically ready for use. With an original TOS 3.06 in the TT, because of the peculiarity of this TOS version is only booted from floppy and the IDE extension is put into operation.<br />
<br />
To directly boot from IDE, the TT needs a TOS with the IDE patch. More details can be found in the forum atari-home.de ([http://forum.atari-home.de/index.php?topic=12683.0]), along with a reference source. With existing IDE TOS patch a special Thunderstorm logo is displayed at start up and in the desktop under Info you get the following note:<br />
<br />
[[Bild:Logo_ts.png]] [[Bild:IDE_Patch.jpg|100px]] [[Bild:TOS306.jpg|100px]]<br />
<br />
<br />
NOTE: The above TOS 3.06 includes the following patches: WinX 2.3n, SHBuffer, BPatch, RamSizeFit, NewLogo, IDE boot. The patched TOS 3.06 is available in following languages: German, English (UK and US), French, Spanish and Swedish.<br />
<br />
More is not necessary. A simple test shows whether the card is correctly plugged in and wired: JP1 from the jumper block of the Thunder pull = off = Thunder disabled. The TT should behave the same despite the Thunder, as without the Thunder.<br />
<br />
Recommended is the combination with the Storm extension ([http://wiki.newtosworld.de/index.php?title=Storm]) to reach the full speed. Especially under Mint, this is clearly noticeable during the installation and the starting process.<br />
<br />
<br />
<br />
.<br />
<br />
== '''Configuration, meanings and contexts''' ==<br />
<br />
The Thunder was tested with various HDD drivers. The best performance is provided by the Thunder IDE interface, together with the Storm Fastram card, when the hard disk driver is loaded into the Fastram.<br />
For the HDDriver version 10 or higher, a feature was introduced under File -> HDDRUTIL settings (HDDRIVER.SYS in Alternate RAM). Furthermore, in the HDDriver (also before version 10) the accelerated mode can be set for IDE devices under Settings -> SCSI driver (Atari / Milan IDE, accelerated mode), which not only offers speed advantages for hard drives but also for CF cards (+ 400 Kbytes / s in accelerated mode).<br />
<br />
[[Bild:HDDriver_10.jpg|200px]] [[Bild:Speed.jpg|240px]] [[Bild:5750.jpg|210px]]<br />
<br />
<br />
In this case, data transfer rates of up to 5750 Kbyte / s can be reached (test program: Xferrate, compared with Falcon, the transmission rate is only 1400 Kbyte / s).<br />
<br />
Note: when using HDDriver, the C: partition must not be set up with byteswap, otherwise from C: can not be booted.<br />
<br />
===Jumpersettings===<br />
<br />
<br />
* JP1 = IDE Interface: '''on = Thunder enabled (Falcon compatible mode)''', off = Thunder disabled<br />
* JP2 = regular or twisted IDE cable: on = twisted (Hardware Byteswap enabled), '''off = regular (untwisted IDE Cable)'''<br />
* JP3 = Smartswap on = SmartSwap enabled, '''off = Smartswap disabled''' <br />
* JP4 = Speedmode on = Slow Mode, '''off = Highspeed Mode'''<br />
* JP5 = Diagnose on = Diagnose enabled, '''off = Normal''' <br />
* JP6 = not in use, for futher features<br />
<br />
The default setting ('''bold''') is: JP1 on, leave all other jumpers open.<br />
<br />
[[Bild:ThunderJumper.jpg|400px]]<br />
<br />
<br />
===Thunder on (JP1), Falcon compatible standard mode===<br />
<br />
JP1 turns on the Thunder. JP1 must therefore always be set, also for the other modes.<br />
If only JP1 is set, the Thunder is operated in Falcon compliant mode. Data exchange with other non-Atari systems is not possible.<br />
<br />
===ByteSwap (JP2), Ppera compatible mode===<br />
<br />
Byteswap is called a mode in which the data lines are twisted (the IDE cable is twisted), this means the lower byte is exchanged with the upper byte during transmission. This technique offers the possibility to read partitions created on the PC without detour on the TT without the CPU having to perform a software byte swap. This saves rendering performance. To use the byteswap mode, however, a special HD driver is required, for example that from ppera.<br />
<br />
The Thunder offers this mode under JP2 for users who want to use the ppera driver with a twisted IDE cable.<br />
<br />
===SmartSwap (JP3), PC/Mac compatible mode===<br />
<br />
Smartswap is a modified mode of byteswap mode. Here, the bytes are only exchanged when actual data are transferred from the IDE device. All other data needed to control the device is not rotated. Thus no special driver is necessary. HDDriver supports this mode.<br />
<br />
The Thunder offers this mode under JP3 for users who want to use the HDDriver and want to use the direct data exchange with a Windows computer or Mac.<br />
<br />
For this, put JP1 and JP3 on. The data carrier (HDDriver without byteswap!) can easily be exchanged between Atari and PC / Mac, ideal for CF cards.<br />
<br />
===Slow Mode (JP4)===<br />
<br />
The Slow Mode is a mode that is used with quite old IDE devices. The Slow Mode is only installed for better compatibility and will not be used with newer devices. In case of problems the setting of JP4 can help. Recommended setting: off.<br />
<br />
<br />
===relationships===<br />
<br />
* JP2 = off and JP3 = off: standard, such as Falcon IDE interface<br />
* JP2 = off and JP3 = on: SmartSwap such as Suska, it means Data bytes are scrambled, except IDENTIFY DEVICE<br />
* JP2 = on and JP3 = no matter: Twisted, it means replace the data lines according to the proposal of ppera<br />

== '''Entfernung der alten Roms''' ==<br />
Die alten ROMS (TOS 1.06 oder 1.62) haben jeweils 28 Pins. Sofern die originalen ROMs verlötet sind, sind diese zu entfernen und durch 2 Stück 32 polige Sockel zu ersetzen.<br />
<br />
Die Markierungskerbe ist immer auf der rechten Seite.<br />
<br />

Geschaltet wird der mittlere Kontakt (2) entweder auf Kontakt 1 oder Kontakt 3.<br />
<br />
Oftmals hat Atari dort 0 Ohm Widerstände verlötet, also Lötbrücken. Manchmal besteht eine kleine Leiterbahnverbindung, die beim Umbau aufzukratzen ist.<br />
<br />
Hinweis: die Veränderung von W103 ist beim Umbau nicht erforderlich, W103 kann also so bleiben!<br />
<br />
Original hat Atari bei den 28poligen ROMS die Verbindungen 2-3 bei W101 und W102 hergestellt.<br />
<br />
Bei der Umrüstung auf 32polige ROMS müssen W101 und W102 auf die neue Position 1-2 gestellt werden.<br />
<br />
Hier wird emfohlen, die beiden 0Ohm Widerstände 2-3 zu entfernen bzw. etwaig bestehende Leiterbahnverbindung 2-3 vorsichtig zu öffnen.<br />
Sodann sollten bei W101 und W102 zwei 3 polige Stiftleisten in die Lötlöcher 1-2-3 eingelötet werden. Auf diese Weise kann man die oben beschrieben Einstellungen mittels Jumperbrücke schnell und einfach realisieren.<br />
<br />
Weiterer Vorteil dieser Lösung: der für den Twister [https://wiki.newtosworld.de/index.php?title=TwiSTEr] wichtige mittlere Pin (2) von W102 ist frei zugänglich, um dort eine Steckkabelverbindung zum Twister herzustellen.<br />

== '''Entfernung der alten Roms''' ==<br />
Die alten ROMS (TOS 1.06 oder 1.62) haben jeweils 28 Pins. Sofern die originalen ROMs verlötet sind, sind diese zu entfernen und durch 2 Stück 32 polige Sockel zu ersetzen.<br />
<br />
Die Markierungskerbe ist immer auf der rechten Seite.<br />
<br />
W102, W102 und W103 sind letztlich 3polige Umschalter für bestimmte Signal, die Roms betreffend.<br />
Geschaltet wird der mittlere Kontakt (2) entweder auf Kontakt 1 oder Kontakt 3.<br />
<br />
Oftmals hat Atari dort 0 Ohm Widerstände verlötet, also Lötbrücken. Manchmal besteht eine kleine Leiterbahnverbindung, die beim Umbau aufzukratzen ist.<br />
<br />
Hinweis: die Veränderung von W103 ist beim Umbau nicht erforderlich, W103 kann also so bleiben!<br />
<br />
Original hat Atari bei den 28poligen ROMS die Verbindungen 2-3 bei W101 und W102 hergestellt.<br />
<br />
Bei der Umrüstung auf 32polige ROMS müssen W101 und W102 auf die neue Position 1-2 gestellt werden.<br />
<br />
Hier wird emfohlen, die beiden 0Ohm Widerstände 2-3 zu entfernen bzw. etwaig bestehende Leiterbahnverbindung 2-3 vorsichtig zu öffnen.<br />
Sodann sollten bei W101 und W102 zwei 3 polige Stiftleisten in die Lötlöcher 1-2-3 eingelötet werden. Auf diese Weise kann man die oben beschrieben Einstellungen mittels Jumperbrücke schnell und einfach realisieren.<br />
<br />

<br />
* Speedy allows you to speed up your CPU of your Atari TT up to 48 MHz.<br />
* You can speed up your coprocessor (MC68882) of your Atari up to 48 MHz.<br />
* If the increasing of speed doesn’t work inside of your TT, you don’t have to rework all steps! Speedy gives you the item to let them inside of your TT with normal speed.<br />
* You could increase the access to your Alternate-RAM, if you bought the new [https://wiki.newtosworld.de/index.php?title=Storm_-_English_Version STORM TT] Rev. G. If you have an older STORM TT Revision, please make a request to your Thunderstorm Team to change the STORM TT to the newest Revision.<br />

== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />
<br />
----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

<br />
Note: The original CPU continues to be used. However, it gets very hot because of the acceleration and should therefore be cooled.<br />
<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />
<br />

<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />
<br />

<br />
<small> ''Pic. 6 a and b: third and fourth type of patch''</small><br />
<br />
<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
Be sure that all your changes matched with the next picture.<br />

<br />
<small>''Pic. 6 c: SMD TT Mainboard with all changes, ready to install SMD-Speedy, /BG cable is in backup mode at this pic''</small><br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />
[[Bild:Abb07a CPU place of SMD TT with divided BG signal.jpg|400px]] [[Bild:Abb07b CPU place of SMD TT with divided BG signal.JPG|400px]] [[Bild:Abb07c_CPU_place_of_SMD_TT_with_divided_BG_signal.JPG|400px]]<br />
<br />
<small>''Pic. 7 a - c: new /BG line and optional backup''</small><br />
<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />
<br />

<br />
<small>''Pic. 8: Speedy with female socket under the PCB for injecting the /BG signal from the CPU''</small><br />
<br />
<br />
'''4th step''':<br />
After all, put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''5th step''': Put the small connector to all three pins of W101 (if there is a jumper - remove the jumper an plug in the prepared 3 colored cables 1:1 from the Speedy.<br />

=== '''<big>PGA TT</big>''' ===<br />
----<br />
<br />
Note: The original CPU is still used. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />
<br />
<br />
Your TT mainboard looks like the next picture. On the next left picture you can see the six ICs. This ist the state machine.<br />
<br />
<br />
'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />
<br />
<br />

<br />
<small>''Pic. 11 a and b: Mainboard PGA TT with marked ICs at left picture and changed to 6 sockets right''</small><br />
<br />
<br />
'''2nd step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
Ensure parallel distances to other components.<br />
<br />
If you look from the right between the new sockets and the PGA Speedy, the first contacts are open!<br />
<br />
<br />

<br />
<small>''Pic. 11 c: Pin clouseup''</small><br />
<br />
<br />
'''3rd step''': split the /BG signal coming from the CPU to MMU. <br />
<br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. <br />
<br />
The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow / copper-coulored at the pictures 12c and 12d) we connect this new signal into the mainboard at the place, shows in the next 4 pictures.<br />
<br />

<br />
<small>''Pic. 12 a - d: CPU of PGA TT with divided BG signal''</small><br />

<br />
<small>''Pic. 13: new /BG to PGA Speedy''</small><br />
<br />
<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />
<br />
<br />

'''Some useful tips for the perfect installation:'''<br />
<br />
# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the PGA Speedy and an extension on the TT-RAM connector (e.g. Storm TT or Thunder).<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily. Take a look at Pic. 20 b.<br />
# <br />
# If you use a PGA Speedy together with a Lightning VME, it fits perfect.<br />
<br />

<br />
=== '''<big>Daughterboard TT</big>''' ===<br />
----<br />
<br />
Note: The original CPU should not be used any further. A new CPU with clean pins is required. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />
<br />
<br />
Your TT mainboard looks like the next picture. <br />
<br />

<small>''Pic. 16: Mainboard DB TT with marked daughterboard''</small><br />
<br />
<br />
'''1st step''': remove the old daughterboard, unplug the connector coming from the oscillator and put the old daughterboard to a good place to store them.<br />
<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />
<br />

''' Here are the instructions for the 2nd step: how to patch und connect the clock line between FPU and Speedy in order to clock the FPU with either 16MHz, 32MHz or 48MHz:'''<br />
<br />
# We remove the original black cable between Atari TT Video Shifter and coprocessor and made a new longer cable, connected to the clock pin of the coprocessor. <br />
#<br />
# At the other side of that new cable please solder a female socket pin and connect this socket pin to the back side of DB Speedy.<br />
# <br />
# The next step is, to connect the oscillator plug at the backside of your new DB-Speedy. <br />

<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />

'''First of all: Please be note, that the installation of Speedy needs really advanced skills of soldering! <br />
If you have a novice skill, please ask a competence person for help!'''<br />
<br />
* Speedy allows you to speed up your CPU of your Atari TT up to 48 MHz.<br />
* You can speed up your coprocessor (MC68882) of your Atari up to 48 MHz.<br />
* If the increasing of speed doesn’t work inside of your TT, you don’t have to rework all steps! Speedy gives you the item to let them inside of your TT with normal speed.<br />
* You could increase the access to your Alternate-RAM, if you bought the new [https://wiki.newtosworld.de/index.php?title=Storm_-_English_Version STORM TT] Rev. G. If you have an older STORM TT Revision, please make a request to your Thunderstorm Team to change the STORM TT to the newest Revision.<br />
<br />
<br />

<br />
== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />
<br />
----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

<br />
Note: The original CPU continues to be used. However, it gets very hot because of the acceleration and should therefore be cooled.<br />
<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />
<br />

<small>''Pic. 5 a and b: Mainboard SMD TT with marked ICs U113 to U116 (=state machine) and after desoldering with new sockets''</small><br />
<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />
<br />

<br />
<small> ''Pic. 6 a and b: third and fourth type of patch''</small><br />
<br />
<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
Be sure that all your changes matched with the next picture.<br />

<br />
<small>''Pic. 6 c: SMD TT Mainboard with all changes, ready to install SMD-Speedy, /BG cable is in backup mode at this pic''</small><br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />
[[Bild:Abb07a CPU place of SMD TT with divided BG signal.jpg|400px]] [[Bild:Abb07b CPU place of SMD TT with divided BG signal.JPG|400px]] [[Bild:Abb07c_CPU_place_of_SMD_TT_with_divided_BG_signal.JPG|400px]]<br />
<br />
<small>''Pic. 7 a - c: new /BG line and optional backup''</small><br />
<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />
<br />

<br />
<small>''Pic. 8: Speedy with female socket under the PCB for injecting the /BG signal from the CPU''</small><br />
<br />
<br />
'''4th step''':<br />
After all, put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''5th step''': Put the small connector to all three pins of W101 (if there is a jumper - remove the jumper an plug in the prepared 3 colored cables 1:1 from the Speedy.<br />

<br />
Note: The original CPU is still used. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />
<br />
<br />
Your TT mainboard looks like the next picture. On the next left picture you can see the six ICs. This ist the state machine.<br />
<br />
<br />
'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />
<br />
<br />

<br />
<small>''Pic. 11 a and b: Mainboard PGA TT with marked ICs at left picture and changed to 6 sockets right''</small><br />
<br />
<br />
'''2nd step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
Ensure parallel distances to other components.<br />
<br />
If you look from the right between the new sockets and the PGA Speedy, the first contacts are open!<br />
<br />
<br />

<br />
<small>''Pic. 11 c: Pin clouseup''</small><br />
<br />
<br />
'''3rd step''': split the /BG signal coming from the CPU to MMU. <br />
<br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. <br />
<br />
The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow / copper-coulored at the pictures 12c and 12d) we connect this new signal into the mainboard at the place, shows in the next 4 pictures.<br />
<br />

<br />
<small>''Pic. 12 a - d: CPU of PGA TT with divided BG signal''</small><br />
<br />
<br />
Now connect the other end of the new /BG line to the Pin marked /BG at the PGA Speedy.<br />

<br />
<small>''Pic. 13: new /BG to PGA Speedy''</small><br />
<br />
<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />
<br />
<br />

'''Some useful tips for the perfect installation:'''<br />
<br />
# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the PGA Speedy and an extension on the TT-RAM connector (e.g. Storm TT or Thunder).<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily. Take a look at Pic. 20 b.<br />
# <br />
# If you use a PGA Speedy together with a Lightning VME, it fits perfect.<br />

<br />
Note: The original CPU should not be used any further. A new CPU with clean pins is required. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />
<br />
<br />
Your TT mainboard looks like the next picture. <br />
<br />

<br />
<small>''Pic. 16: Mainboard DB TT with marked daughterboard''</small><br />
<br />
<br />
'''1st step''': remove the old daughterboard, unplug the connector coming from the oscillator and put the old daughterboard to a good place to store them.<br />
<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />
<br />
<br />

<br />
<small>''Pic. 17a - b: Coprocessor clock patch made by Atari themselves''</small><br />
<br />
<br />
By a fluke the signal clock line of the coprocessor is cut through via Atari. <br />
<br />
<br />
''' Here are the instructions for the 2nd step: how to patch und connect the clock line between FPU and Speedy in order to clock the FPU with either 16MHz, 32MHz or 48MHz:'''<br />
<br />
# We remove the original black cable between Atari TT Video Shifter and coprocessor and made a new longer cable, connected to the clock pin of the coprocessor. <br />
#<br />
# At the other side of that new cable please solder a female socket pin and connect this socket pin to the back side of DB Speedy.<br />
# <br />
# The next step is, to connect the oscillator plug at the backside of your new DB-Speedy. <br />
# <br />
# Please be sure, that the black cable from oscillator pin seven is connect to the “GND”. <br />

== '''Last steps''' ==<br />
<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />
<br />
After all reassemble the rest of your TT. All work is done. Gratulations!<br />

'''First of all: Please be note, that the installation of Speedy needs really advanced skills of soldering! <br />
If you have a novice skill, please ask a competence person for help!'''<br />
<br />
* Speedy allows you to speed up your CPU of your Atari TT up to 48 MHz.<br />
* You can speed up your coprocessor (MC68882) of your Atari up to 48 MHz.<br />
* If the increasing of speed doesn’t work inside of your TT, you don’t have to rework all steps! Speedy gives you the item to let them inside of your TT with normal speed.<br />
* You could increase the access to your Alternate-RAM, if you bought the new [https://wiki.newtosworld.de/index.php?title=Storm_-_English_Version STORM TT] Rev. G. If you have an older STORM TT Revision, please make a request to your Thunderstorm Team to change the STORM TT to the newest Revision.<br />
<br />
<br />
----<br />
<br />
== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />
<br />
----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

Note: The original CPU continues to be used. However, it gets very hot because of the acceleration and should therefore be cooled.<br />
<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />

<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />

* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />

<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />

<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />

<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />

'''4th step''':<br />
After all, put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''5th step''': Put the small connector to all three pins of W101 (if there is a jumper - remove the jumper an plug in the prepared 3 colored cables 1:1 from the Speedy.<br />

Note: The original CPU is still used. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />
<br />
<br />
Your TT mainboard looks like the next picture. On the next left picture you can see the six ICs. This ist the state machine.<br />
<br />
<br />
'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />
<br />

<br />
<small>''Pic. 11 a and b: Mainboard PGA TT with marked ICs at left picture and changed to 6 sockets right''</small><br />
<br />
<br />
'''2nd step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
Ensure parallel distances to other components.<br />
<br />
If you look from the right between the new sockets and the PGA Speedy, the first contacts are open!<br />
<br />
<br />

<br />
<small>''Pic. 11 c: Pin clouseup''</small><br />
<br />
<br />
'''3rd step''': split the /BG signal coming from the CPU to MMU. <br />
<br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. <br />
<br />
The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow / copper-coulored at the pictures 12c and 12d) we connect this new signal into the mainboard at the place, shows in the next 4 pictures.<br />

<br />
<small>''Pic. 13: new /BG to PGA Speedy''</small><br />
<br />
<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />
<br />
<br />

'''Some useful tips for the perfect installation:'''<br />
<br />
# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the PGA Speedy and an extension on the TT-RAM connector (e.g. Storm TT or Thunder).<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily. Take a look at Pic. 20 b.<br />
# <br />
# If you use a PGA Speedy together with a Lightning VME, it fits perfect.<br />

<br />
Note: The original CPU should not be used any further. A new CPU with clean pins is required. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />
<br />
<br />
Your TT mainboard looks like the next picture. <br />

<small>''Pic. 16: Mainboard DB TT with marked daughterboard''</small><br />
<br />
<br />
'''1st step''': remove the old daughterboard, unplug the connector coming from the oscillator and put the old daughterboard to a good place to store them.<br />
<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />
<br />

<br />
By a fluke the signal clock line of the coprocessor is cut through via Atari. <br />
<br />
<br />
''' Here are the instructions for the 2nd step: how to patch und connect the clock line between FPU and Speedy in order to clock the FPU with either 16MHz, 32MHz or 48MHz:'''<br />
<br />
# We remove the original black cable between Atari TT Video Shifter and coprocessor and made a new longer cable, connected to the clock pin of the coprocessor. <br />
#<br />
# At the other side of that new cable please solder a female socket pin and connect this socket pin to the back side of DB Speedy.<br />
# <br />
# The next step is, to connect the oscillator plug at the backside of your new DB-Speedy. <br />
# <br />
# Please be sure, that the black cable from oscillator pin seven is connect to the “GND”. <br />

== '''Last steps''' ==<br />
<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />
<br />
After all reassemble the rest of your TT. All work is done. Gratulations!<br />

<br />
'''First of all: Please be note, that the installation of Speedy needs really advanced skills of soldering! <br />
If you have a novice skill, please ask a competence person for help!'''<br />
<br />
* Speedy allows you to speed up your CPU of your Atari TT up to 48 MHz.<br />
* You can speed up your coprocessor (MC68882) of your Atari up to 48 MHz.<br />
* If the increasing of speed doesn’t work inside of your TT, you don’t have to rework all steps! Speedy gives you the item to let them inside of your TT with normal speed.<br />
* You could increase the access to your Alternate-RAM, if you bought the new [https://wiki.newtosworld.de/index.php?title=Storm_-_English_Version STORM TT] Rev. G. If you have an older STORM TT Revision, please make a request to your Thunderstorm Team to change the STORM TT to the newest Revision.<br />
<br />
<br />
----<br />
<br />
== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />
<br />
----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

<br />
Note: The original CPU continues to be used. However, it gets very hot because of the acceleration and should therefore be cooled.<br />
<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />
<br />

<small>''Pic. 5a and b: Mainboard SMD TT with marked ICs U113 to U116 (=state machine) and after desoldering with new sockets''</small><br />
<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />
<br />

<br />
<small> ''Pic. 6a and b: third and fourth type of patch''</small><br />
<br />
<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />
[[Bild:Abb07a CPU place of SMD TT with divided BG signal.jpg|400px]] [[Bild:Abb07b CPU place of SMD TT with divided BG signal.JPG|400px]] [[Bild:Abb07c_CPU_place_of_SMD_TT_with_divided_BG_signal.JPG|400px]]<br />
<br />
<small>''Pic. 7a - c: new /BG line and optional backup''</small><br />
<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />

Your TT mainboard looks like the next picture. On the next left picture you can see the six ICs. This ist the state machine.<br />
<br />
<br />
'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />

<br />
Ensure parallel distances to other components.<br />
<br />
If you look from the right between the new sockets and the PGA Speedy, the first contacts are open!<br />

<br />
<br />
'''3rd step''': split the /BG signal coming from the CPU to MMU. <br />
<br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. <br />
<br />
The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow / copper-coulored at the pictures 12c and 12d) we connect this new signal into the mainboard at the place, shows in the next 4 pictures.<br />

<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />

'''Some useful tips for the perfect installation:'''<br />
<br />
# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the PGA Speedy and an extension on the TT-RAM connector (e.g. Storm TT or Thunder).<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily. Take a look at Pic. 20 b.<br />
# <br />
# If you use a PGA Speedy together with a Lightning VME, it fits perfect.<br />

<br />
Note: The original CPU should not be used any further. A new CPU with clean pins is required. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />
<br />
<br />
Your TT mainboard looks like the next picture. <br />

<br />
<br />
'''1st step''': remove the old daughterboard, unplug the connector coming from the oscillator and put the old daughterboard to a good place to store them.<br />
<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />

<br />
By a fluke the signal clock line of the coprocessor is cut through via Atari. <br />
<br />
<br />
''' Here are the instructions for the 2nd step: how to patch und connect the clock line between FPU and Speedy in order to clock the FPU with either 16MHz, 32MHz or 48MHz:'''<br />
<br />
# We remove the original black cable between Atari TT Video Shifter and coprocessor and made a new longer cable, connected to the clock pin of the coprocessor. <br />
#<br />
# At the other side of that new cable please solder a female socket pin and connect this socket pin to the back side of DB Speedy.<br />
# <br />
# The next step is, to connect the oscillator plug at the backside of your new DB-Speedy. <br />
# <br />
# Please be sure, that the black cable from oscillator pin seven is connect to the “GND”. <br />

== '''Last steps''' ==<br />
<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />
<br />
After all reassemble the rest of your TT. All work is done. Gratulations!<br />

<br />
'''First of all: Please be note, that the installation of Speedy needs really advanced skills of soldering! <br />
If you have a novice skill, please ask a competence person for help!'''<br />
<br />
* Speedy allows you to speed up your CPU of your Atari TT up to 48 MHz.<br />
* You can speed up your coprocessor (MC68882) of your Atari up to 48 MHz.<br />
* If the increasing of speed doesn’t work inside of your TT, you don’t have to rework all steps! Speedy gives you the item to let them inside of your TT with normal speed.<br />
* You could increase the access to your Alternate-RAM, if you bought the new [https://wiki.newtosworld.de/index.php?title=Storm_-_English_Version STORM TT] Rev. G. If you have an older STORM TT Revision, please make a request to your Thunderstorm Team to change the STORM TT to the newest Revision.<br />
<br />
<br />
----<br />
<br />
== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />
<br />
----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

<br />
Note: The original CPU continues to be used. However, it gets very hot because of the acceleration and should therefore be cooled.<br />
<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />
<br />

<small>''Pic. 5a and b: Mainboard SMD TT with marked ICs U113 to U116 (=state machine) and after desoldering with new sockets''</small><br />
<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />
<br />

<br />
<small> ''Pic. 6a and b: third and fourth type of patch''</small><br />
<br />
<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />
[[Bild:Abb07a CPU place of SMD TT with divided BG signal.jpg|400px]] [[Bild:Abb07b CPU place of SMD TT with divided BG signal.JPG|400px]] [[Bild:Abb07c_CPU_place_of_SMD_TT_with_divided_BG_signal.JPG|400px]]<br />
<br />
<small>''Pic. 7a - c: new /BG line and optional backup''</small><br />
<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />

<br />
'''4th step''':<br />
After all, put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''5th step''': Put the small connector to all three pins of W101 (if there is a jumper - remove the jumper an plug in the prepared 3 colored cables 1:1 from the Speedy.<br />

'''2nd step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
Ensure parallel distances to other components.<br />
<br />
If you look from the right between the new sockets and the PGA Speedy, the first contacts are open!<br />

<br />
<br />
'''3rd step''': split the /BG signal coming from the CPU to MMU. <br />
<br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. <br />
<br />
The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow / copper-coulored at the pictures 12c and 12d) we connect this new signal into the mainboard at the place, shows in the next 4 pictures.<br />

<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />

'''Some useful tips for the perfect installation:'''<br />
<br />
# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the PGA Speedy and an extension on the TT-RAM connector (e.g. Storm TT or Thunder).<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily. Take a look at Pic. 20 b.<br />
# <br />
# If you use a PGA Speedy together with a Lightning VME, it fits perfect.<br />

<br />
Note: The original CPU should not be used any further. A new CPU with clean pins is required. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />
<br />
<br />
Your TT mainboard looks like the next picture. <br />

<br />
'''1st step''': remove the old daughterboard, unplug the connector coming from the oscillator and put the old daughterboard to a good place to store them.<br />
<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />

<br />
By a fluke the signal clock line of the coprocessor is cut through via Atari. <br />
<br />
<br />
''' Here are the instructions for the 2nd step: how to patch und connect the clock line between FPU and Speedy in order to clock the FPU with either 16MHz, 32MHz or 48MHz:'''<br />
<br />
# We remove the original black cable between Atari TT Video Shifter and coprocessor and made a new longer cable, connected to the clock pin of the coprocessor. <br />
#<br />
# At the other side of that new cable please solder a female socket pin and connect this socket pin to the back side of DB Speedy.<br />
# <br />
# The next step is, to connect the oscillator plug at the backside of your new DB-Speedy. <br />
# <br />
# Please be sure, that the black cable from oscillator pin seven is connect to the “GND”. <br />

== '''Last steps''' ==<br />
<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />
<br />
After all reassemble the rest of your TT. All work is done. Gratulations!<br />

'''First of all: Please be note, that the installation of Speedy needs really advanced skills of soldering! <br />
If you have a novice skill, please ask a competence person for help!'''<br />
<br />
* Speedy allows you to speed up your CPU of your Atari TT up to 48 MHz.<br />
* You can speed up your coprocessor (MC68882) of your Atari up to 48 MHz.<br />
* If the increasing of speed doesn’t work inside of your TT, you don’t have to rework all steps! Speedy gives you the item to let them inside of your TT with normal speed.<br />
* You could increase the access to your Alternate-RAM, if you bought the new [https://wiki.newtosworld.de/index.php?title=Storm_-_English_Version STORM TT] Rev. G. If you have an older STORM TT Revision, please make a request to your Thunderstorm Team to change the STORM TT to the newest Revision.<br />
<br />
<br />
----<br />
<br />
== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />
<br />
----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

<br />
Note: The original CPU continues to be used. However, it gets very hot because of the acceleration and should therefore be cooled.<br />
<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />
<br />

<small>''Pic. 5a and b: Mainboard SMD TT with marked ICs U113 to U116 (=state machine) and after desoldering with new sockets''</small><br />
<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />
<br />

<br />
<small> ''Pic. 6a and b: third and fourth type of patch''</small><br />
<br />
<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />
[[Bild:Abb07a CPU place of SMD TT with divided BG signal.jpg|400px]] [[Bild:Abb07b CPU place of SMD TT with divided BG signal.JPG|400px]] [[Bild:Abb07c_CPU_place_of_SMD_TT_with_divided_BG_signal.JPG|400px]]<br />
<br />
<small>''Pic. 7a - c: new /BG line and optional backup''</small><br />
<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />

<br />
'''4th step''':<br />
After all, put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''5th step''': Put the small connector to all three pins of W101 (if there is a jumper - remove the jumper an plug in the prepared 3 colored cables 1:1 from the Speedy.<br />

Note: The original CPU is still used. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />
<br />
<br />
Your TT mainboard looks like the next picture. On the next left picture you can see the six ICs. This ist the state machine.<br />
<br />
<br />
'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />

<br />
Ensure parallel distances to other components.<br />
<br />
If you look from the right between the new sockets and the PGA Speedy, the first contacts are open!<br />

'''3rd step''': split the /BG signal coming from the CPU to MMU. <br />
<br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. <br />
<br />
The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow / copper-coulored at the pictures 12c and 12d) we connect this new signal into the mainboard at the place, shows in the next 4 pictures.<br />

'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />

'''Some useful tips for the perfect installation:'''<br />
<br />
# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the PGA Speedy and an extension on the TT-RAM connector (e.g. Storm TT or Thunder).<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily. Take a look at Pic. 20 b.<br />
# <br />
# If you use a PGA Speedy together with a Lightning VME, it fits perfect.<br />

Note: The original CPU should not be used any further. A new CPU with clean pins is required. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />
<br />
<br />
Your TT mainboard looks like the next picture. <br />

<br />
'''1st step''': remove the old daughterboard, unplug the connector coming from the oscillator and put the old daughterboard to a good place to store them.<br />
<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />

''' Here are the instructions for the 2nd step: how to patch und connect the clock line between FPU and Speedy in order to clock the FPU with either 16MHz, 32MHz or 48MHz:'''<br />
<br />
# We remove the original black cable between Atari TT Video Shifter and coprocessor and made a new longer cable, connected to the clock pin of the coprocessor. <br />
#<br />
# At the other side of that new cable please solder a female socket pin and connect this socket pin to the back side of DB Speedy.<br />
# <br />
# The next step is, to connect the oscillator plug at the backside of your new DB-Speedy. <br />

== '''Last steps''' ==<br />
<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />
<br />
After all reassemble the rest of your TT. All work is done. Gratulations!<br />

<br />
'''First of all: Please be note, that the installation of Speedy needs really advanced skills of soldering! <br />
If you have a novice skill, please ask a competence person for help!'''<br />
<br />
* Speedy allows you to speed up your CPU of your Atari TT up to 48 MHz.<br />
* You can speed up your coprocessor (MC68882) of your Atari up to 48 MHz.<br />
* If the increasing of speed doesn’t work inside of your TT, you don’t have to rework all steps! Speedy gives you the item to let them inside of your TT with normal speed.<br />
* You could increase the access to your Alternate-RAM, if you bought the new [https://wiki.newtosworld.de/index.php?title=Storm_-_English_Version STORM TT] Rev. G. If you have an older STORM TT Revision, please make a request to your Thunderstorm Team to change the STORM TT to the newest Revision.<br />
<br />
<br />
----<br />
<br />
== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />
<br />
----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

<br />
Note: The original CPU continues to be used. However, it gets very hot because of the acceleration and should therefore be cooled.<br />
<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />
<br />

<small>''Pic. 5a and b: Mainboard SMD TT with marked ICs U113 to U116 (=state machine) and after desoldering with new sockets''</small><br />
<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />
<br />

<br />
<small> ''Pic. 6a and b: third and fourth type of patch''</small><br />
<br />
<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />
[[Bild:Abb07a CPU place of SMD TT with divided BG signal.jpg|400px]] [[Bild:Abb07b CPU place of SMD TT with divided BG signal.JPG|400px]] [[Bild:Abb07c_CPU_place_of_SMD_TT_with_divided_BG_signal.JPG|400px]]<br />
<br />
<small>''Pic. 7a - c: new /BG line and optional backup''</small><br />
<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />

<br />
<br />
'''4th step''':<br />
After all, put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''5th step''': Put the small connector to all three pins of W101 (if there is a jumper - remove the jumper an plug in the prepared 3 colored cables 1:1 from the Speedy.<br />

<br />
Note: The original CPU is still used. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />
<br />
<br />
Your TT mainboard looks like the next picture. On the next left picture you can see the six ICs. This ist the state machine.<br />
<br />
<br />
'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />
<br />

<br />
<small>''Pic. 11 a and b: Mainboard PGA TT with marked ICs at left picture and changed to 6 sockets right''</small><br />
<br />
<br />
'''2nd step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
Ensure parallel distances to other components.<br />
<br />
If you look from the right between the new sockets and the PGA Speedy, the first contacts are open!<br />

<br />
<br />
'''3rd step''': split the /BG signal coming from the CPU to MMU. <br />
<br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. <br />
<br />
The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow / copper-coulored at the pictures 12c and 12d) we connect this new signal into the mainboard at the place, shows in the next 4 pictures.<br />

<small>''Pic. 12 a - d: CPU of PGA TT with divided BG signal''</small><br />
<br />
<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />

'''Some useful tips for the perfect installation:'''<br />
<br />
# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the PGA Speedy and an extension on the TT-RAM connector (e.g. Storm TT or Thunder).<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily. Take a look at Pic. 20 b.<br />
# <br />
# If you use a PGA Speedy together with a Lightning VME, it fits perfect.<br />

Note: The original CPU should not be used any further. A new CPU with clean pins is required. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />

<br />
'''1st step''': remove the old daughterboard, unplug the connector coming from the oscillator and put the old daughterboard to a good place to store them.<br />
<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />

<br />
<br />
By a fluke the signal clock line of the coprocessor is cut through via Atari. <br />
<br />
<br />
''' Here are the instructions for the 2nd step: how to patch und connect the clock line between FPU and Speedy in order to clock the FPU with either 16MHz, 32MHz or 48MHz:'''<br />
<br />
# We remove the original black cable between Atari TT Video Shifter and coprocessor and made a new longer cable, connected to the clock pin of the coprocessor. <br />
#<br />
# At the other side of that new cable please solder a female socket pin and connect this socket pin to the back side of DB Speedy.<br />
# <br />
# The next step is, to connect the oscillator plug at the backside of your new DB-Speedy. <br />
# <br />
# Please be sure, that the black cable from oscillator pin seven is connect to the “GND”. <br />

== '''Last steps''' ==<br />
<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />
<br />
After all reassemble the rest of your TT. All work is done. Gratulations!<br />

'''First of all: Please be note, that the installation of Speedy needs really advanced skills of soldering! <br />
If you have a novice skill, please ask a competence person for help!'''<br />
<br />
* Speedy allows you to speed up your CPU of your Atari TT up to 48 MHz.<br />
* You can speed up your coprocessor (MC68882) of your Atari up to 48 MHz.<br />
* If the increasing of speed doesn’t work inside of your TT, you don’t have to rework all steps! Speedy gives you the item to let them inside of your TT with normal speed.<br />
* You could increase the access to your Alternate-RAM, if you bought the new [https://wiki.newtosworld.de/index.php?title=Storm_-_English_Version STORM TT] Rev. G. If you have an older STORM TT Revision, please make a request to your Thunderstorm Team to change the STORM TT to the newest Revision.<br />
<br />
<br />
----<br />
<br />
== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />
<br />
----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

<br />
Note: The original CPU continues to be used. However, it gets very hot because of the acceleration and should therefore be cooled.<br />
<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />
<br />
[[Bild:Abb04 Mainboard SMD-TT with marked IC.JPG|400px]] [[Bild:Abb05a six new sockets for SMD Speedy.JPG|400px]]<br />
<br />
<small>''Pic. 5a and b: Mainboard SMD TT with marked ICs U113 to U116 (=state machine) and after desoldering with new sockets''</small><br />
<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />
<br />

<br />
<small> ''Pic. 6a and b: third and fourth type of patch''</small><br />
<br />
<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />
[[Bild:Abb07a CPU place of SMD TT with divided BG signal.jpg|400px]] [[Bild:Abb07b CPU place of SMD TT with divided BG signal.JPG|400px]] [[Bild:Abb07c_CPU_place_of_SMD_TT_with_divided_BG_signal.JPG|400px]]<br />
<br />
<small>''Pic. 7a - c: new /BG line and optional backup''</small><br />
<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />
<br />

<br />
<br />
'''4th step''':<br />
After all, put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''5th step''': Put the small connector to all three pins of W101 (if there is a jumper - remove the jumper an plug in the prepared 3 colored cables 1:1 from the Speedy.<br />

=== '''<big>PGA TT</big>''' ===<br />
----<br />
<br />
Note: The original CPU is still used. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />
<br />
<br />
Your TT mainboard looks like the next picture. On the next left picture you can see the six ICs. This ist the state machine.<br />
<br />
<br />
'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />
<br />
<br />

<br />
<small>''Pic. 11 a and b: Mainboard PGA TT with marked ICs at left picture and changed to 6 sockets right''</small><br />
<br />
<br />
'''2nd step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
Ensure parallel distances to other components.<br />
<br />
If you look from the right between the new sockets and the PGA Speedy, the first contacts are open!<br />
<br />
<br />
[[Bild:Abb11a_PGA_Speedy_Pin_closeup.JPG|400px]]<br />
<br />
<small>''Pic. 11 c: Pin clouseup''</small><br />
<br />
<br />
'''3rd step''': split the /BG signal coming from the CPU to MMU. <br />
<br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. <br />
<br />
The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow / copper-coulored at the pictures 12c and 12d) we connect this new signal into the mainboard at the place, shows in the next 4 pictures.<br />

<br />
<small>''Pic. 12 a - d: CPU of PGA TT with divided BG signal''</small><br />
<br />
<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />
<br />

'''1st step''': remove the old daughterboard, unplug the connector coming from the oscillator and put the old daughterboard to a good place to store them.<br />
<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />

# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the CPU and an extension on the TT-RAM connector (e.g. Storm TT or Thunder) and to avoid heat build-up and short circuits.<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily.<br />
# <br />
# If you use a DB Speedy together with a Lightning VME, the connection of the left ribbon cable on the Lightning VME is very tight. Ask Team Thunderstorm to get a specially customized version of the Lighting VME to solve this small problem.<br />

== '''Last steps''' ==<br />
<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />
<br />
After all reassemble the rest of your TT. All work is done. Gratulations!<br />

<br />
'''First of all: Please be note, that the installation of Speedy needs really advanced skills of soldering! <br />
If you have a novice skill, please ask a competence person for help!'''<br />
<br />
* Speedy allows you to speed up your CPU of your Atari TT up to 48 MHz.<br />
* You can speed up your coprocessor (MC68882) of your Atari up to 48 MHz.<br />
* If the increasing of speed doesn’t work inside of your TT, you don’t have to rework all steps! Speedy gives you the item to let them inside of your TT with normal speed.<br />
* You could increase the access to your Alternate-RAM, if you bought the new [https://wiki.newtosworld.de/index.php?title=Storm_-_English_Version STORM TT] Rev. G. If you have an older STORM TT Revision, please make a request to your Thunderstorm Team to change the STORM TT to the newest Revision.<br />
<br />
<br />
----<br />
<br />
== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />
<br />
----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

----<br />
<br />
Note: The original CPU continues to be used. However, it gets very hot because of the acceleration and should therefore be cooled.<br />
<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />
<br />
[[Bild:Abb04 Mainboard SMD-TT with marked IC.JPG|400px]] [[Bild:Abb05a six new sockets for SMD Speedy.JPG|400px]]<br />
<br />
<small>''Pic. 5a and b: Mainboard SMD TT with marked ICs U113 to U116 (=state machine) and after desoldering with new sockets''</small><br />
<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />
<br />
[[Bild:Abb06_Third_type_of_patch.JPG|400px]] [[Bild:Abb06b_Fourth_type_of_patch.JPG|400px]]<br />
<br />
<small> ''Pic. 6a and b: third and fourth type of patch''</small><br />
<br />
<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />
[[Bild:Abb07a CPU place of SMD TT with divided BG signal.jpg|400px]] [[Bild:Abb07b CPU place of SMD TT with divided BG signal.JPG|400px]] [[Bild:Abb07c_CPU_place_of_SMD_TT_with_divided_BG_signal.JPG|400px]]<br />
<br />
<small>''Pic. 7a - c: new /BG line and optional backup''</small><br />
<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />
<br />

<br />
<small>''Pic. 8: Speedy with female socket under the PCB for injecting the /BG signal from the CPU''</small><br />

<br />
<small>''Pic 9:SMD TT Mainboard with all changes, ready to install SMD-Speedy, /BG cable is in backup mode at this pic''</small><br />
<br />
<br />
'''4th step''':<br />
After all, put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''5th step''': Put the small connector to all three pins of W101 (if there is a jumper - remove the jumper an plug in the prepared 3 colored cables 1:1 from the Speedy.<br />

That´s it!<br />

<br />
=== '''<big>PGA TT</big>''' ===<br />
----<br />
<br />
Note: The original CPU is still used. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />
<br />
<br />
Your TT mainboard looks like the next picture. On the next left picture you can see the six ICs. This ist the state machine.<br />
<br />
<br />
'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />
<br />
<br />

<br />
<small>''Pic. 11 a and b: Mainboard PGA TT with marked ICs at left picture and changed to 6 sockets right''</small><br />
<br />
<br />
'''2nd step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
Ensure parallel distances to other components.<br />
<br />
If you look from the right between the new sockets and the PGA Speedy, the first contacts are open!<br />
<br />
<br />
[[Bild:Abb11a_PGA_Speedy_Pin_closeup.JPG|400px]]<br />
<br />
<small>''Pic. 11 c: Pin clouseup''</small><br />
<br />
<br />
'''3rd step''': split the /BG signal coming from the CPU to MMU. <br />
<br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. <br />
<br />
The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow / copper-coulored at the pictures 12c and 12d) we connect this new signal into the mainboard at the place, shows in the next 4 pictures.<br />
<br />

<br />
<small>''Pic. 12 a - d: CPU of PGA TT with divided BG signal''</small><br />
<br />
<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />
<br />
<br />

'''Some useful tips for the perfect installation:'''<br />
<br />
# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the PGA Speedy and an extension on the TT-RAM connector (e.g. Storm TT or Thunder).<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily. Take a look at Pic. <br />

<br />
=== '''<big>Daughterboard TT</big>''' ===<br />
----<br />
<br />
Note: The original CPU should not be used any further. A new CPU with clean pins is required. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />
<br />
<br />
Your TT mainboard looks like the next picture. <br />
<br />
[[Bild:Abb16_Mainboard_DB_TT_with_marked_Daughterboard.JPG|400px]]<br />
<br />
<small>''Pic. 16: Mainboard DB TT with marked daughterboard''</small><br />
<br />
<br />
'''1st step''': remove the old daughterboard, unplug the connector coming from the oscillator and put the old daughterboard to a good place to store them.<br />
<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />
<br />
<br />

<br />
<small>''Pic. 17a - b: Coprocessor clock patch made by Atari themselves''</small><br />
<br />
<br />
By a fluke the signal clock line of the coprocessor is cut through via Atari. <br />
<br />
<br />
''' Here are the instructions for the 2nd step: how to patch und connect the clock line between FPU and Speedy in order to clock the FPU with either 16MHz, 32MHz or 48MHz:'''<br />
<br />
# We remove the original black cable between Atari TT Video Shifter and coprocessor and made a new longer cable, connected to the clock pin of the coprocessor. <br />
#<br />
# At the other side of that new cable please solder a female socket pin and connect this socket pin to the back side of DB Speedy.<br />
# <br />
# The next step is, to connect the oscillator plug at the backside of your new DB-Speedy. <br />
# <br />
# Please be sure, that the black cable from oscillator pin seven is connect to the “GND”. <br />

== '''Last steps''' ==<br />
<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />

<br />
* Speedy allows you to speed up your CPU of your Atari TT up to 48 MHz.<br />
* You can speed up your coprocessor (MC68882) of your Atari up to 48 MHz.<br />
* If the increasing of speed doesn’t work inside of your TT, you don’t have to rework all steps! Speedy gives you the item to let them inside of your TT with normal speed.<br />
* You could increase the access to your Alternate-RAM, if you bought the new [https://wiki.newtosworld.de/index.php?title=Storm_-_English_Version STORM TT] Rev. G. If you have an older STORM TT Revision, please make a request to your Thunderstorm Team to change the STORM TT to the newest Revision.<br />
<br />
<br />
----<br />
<br />
== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />
<br />
----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

----<br />
<br />
Note: The original CPU continues to be used. However, it gets very hot because of the acceleration and should therefore be cooled.<br />
<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />
<br />
[[Bild:Abb04 Mainboard SMD-TT with marked IC.JPG|400px]] [[Bild:Abb05a six new sockets for SMD Speedy.JPG|400px]]<br />
<br />
<small>''Pic. 5a and b: Mainboard SMD TT with marked ICs U113 to U116 (=state machine) and after desoldering with new sockets''</small><br />
<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />
<br />
[[Bild:Abb06_Third_type_of_patch.JPG|400px]] [[Bild:Abb06b_Fourth_type_of_patch.JPG|400px]]<br />
<br />
<small> ''Pic. 6a and b: third and fourth type of patch''</small><br />
<br />
<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />
[[Bild:Abb07a CPU place of SMD TT with divided BG signal.jpg|400px]] [[Bild:Abb07b CPU place of SMD TT with divided BG signal.JPG|400px]] [[Bild:Abb07c_CPU_place_of_SMD_TT_with_divided_BG_signal.JPG|400px]]<br />
<br />
<small>''Pic. 7a - c: new /BG line and optional backup''</small><br />
<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />
<br />

<br />
<small>''Pic 9:SMD TT Mainboard with all changes, ready to install SMD-Speedy, /BG cable is in backup mode at this pic''</small><br />
<br />
<br />
'''4th step''':<br />
After all, put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''5th step''': Put the small connector to all three pins of W101 (if there is a jumper - remove the jumper an plug in the prepared 3 colored cables 1:1 from the Speedy.<br />

That´s it!<br />

<br />
=== '''<big>PGA TT</big>''' ===<br />
----<br />
<br />
Note: The original CPU is still used. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />
<br />
<br />
Your TT mainboard looks like the next picture. On the next left picture you can see the six ICs. This ist the state machine.<br />
<br />
<br />
'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />
<br />
<br />

<br />
<small>''Pic. 11 a and b: Mainboard PGA TT with marked ICs at left picture and changed to 6 sockets right''</small><br />
<br />
<br />
'''2nd step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
Ensure parallel distances to other components.<br />
<br />
If you look from the right between the new sockets and the PGA Speedy, the first contacts are open!<br />
<br />
<br />
[[Bild:Abb11a_PGA_Speedy_Pin_closeup.JPG|400px]]<br />
<br />
<small>''Pic. 11 c: Pin clouseup''</small><br />
<br />
<br />
'''3rd step''': split the /BG signal coming from the CPU to MMU. <br />
<br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. <br />
<br />
The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow / copper-coulored at the pictures 12c and 12d) we connect this new signal into the mainboard at the place, shows in the next 4 pictures.<br />
<br />
<br />

<br />
<small>''Pic. 12 a - d: CPU of PGA TT with divided BG signal''</small><br />
<br />
<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />
<br />
<br />

<br />
<small>''Pic. 14 a and b: Cable between PGA Sppedy and Pin 1 of U704''</small><br />
<br />
<br />
'''6th step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
<br />
Be sure that your changes matched with the next picture.<br />

<br />
<br />
----<br />
<br />
=== '''<big>Daughterboard TT</big>''' ===<br />
----<br />
<br />
Note: The original CPU should not be used any further. A new CPU with clean pins is required. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />
<br />
<br />
Your TT mainboard looks like the next picture. <br />
<br />
[[Bild:Abb16_Mainboard_DB_TT_with_marked_Daughterboard.JPG|400px]]<br />
<br />
<small>''Pic. 16: Mainboard DB TT with marked daughterboard''</small><br />
<br />
<br />
'''1st step''': remove the old daughterboard, unplug the connector coming from the oscillator and put the old daughterboard to a good place to store them.<br />
<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />
<br />
<br />
[[Bild:Abb17a_DB-TT_Co-Pro-Patch_01_mod.JPG|400px]] [[Bild:Abb17b_DB-TT_Co-Pro-Patch_02_mod.JPG|400px]] <br />
<br />
<small>''Pic. 17a - b: Coprocessor clock patch made by Atari themselves''</small><br />
<br />
<br />
By a fluke the signal clock line of the coprocessor is cut through via Atari. <br />
<br />
<br />
''' Here are the instructions for the 2nd step: how to patch und connect the clock line between FPU and Speedy in order to clock the FPU with either 16MHz, 32MHz or 48MHz:'''<br />
<br />
# We remove the original black cable between Atari TT Video Shifter and coprocessor and made a new longer cable, connected to the clock pin of the coprocessor. <br />
#<br />
# At the other side of that new cable please solder a female socket pin and connect this socket pin to the back side of DB Speedy.<br />
# <br />
# The next step is, to connect the oscillator plug at the backside of your new DB-Speedy. <br />
# <br />
# Please be sure, that the black cable from oscillator pin seven is connect to the “GND”. <br />
<br />
<br />
Be sure that your changes matched with the next picture.<br />

<br />
<br />
'''3rd step''': Plug the DB-Speedy into the existing CPU socket. Be careful!<br />
<br />
'''4th step''': Plug in the new 68030 CPU (PGA type, coldcap preferd, it should be a B or C variant with 40 or 50 Mhz, e.g. 68030RC40B)<br />

<br />
That´s it!<br />
<br />
<br />
'''Some useful tips for the perfect installation:'''<br />
<br />
# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the CPU and an extension on the TT-RAM connector (e.g. Storm TT or Thunder) and to avoid heat build-up and short circuits.<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily.<br />
# <br />
# If you use a DB Speedy together with a Lightning VME, the connection of the left ribbon cable on the Lightning VME is very tight. Ask Team Thunderstorm to get a specially customized version of the Lighting VME to solve this small problem.<br />

<br />
== '''Last steps''' ==<br />
<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />
<br />
After all reassemble the rest of your TT. All work is done. Gratulations!<br />

== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />
<br />
----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

<br />
Note: The original CPU continues to be used. However, it gets very hot because of the acceleration and should therefore be cooled.<br />
<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />
<br />

<br />
<small>''Pic. 5a and b: Mainboard SMD TT with marked ICs U113 to U116 (=state machine) and after desoldering with new sockets''</small><br />
<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />
<br />

<br />
<small> ''Pic. 6a and b: third and fourth type of patch''</small><br />
<br />
<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />

<br />
<small>''Pic. 7a - c: new /BG line and optional backup''</small><br />
<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />

<br />
<br />
'''4th step''':<br />
After all, put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''5th step''': Put the small connector to all three pins of W101 (if there is a jumper - remove the jumper an plug in the prepared 3 colored cables 1:1 from the Speedy.<br />

----<br />
<br />
Note: The original CPU is still used. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />
<br />
<br />
Your TT mainboard looks like the next picture. On the next left picture you can see the six ICs. This ist the state machine.<br />
<br />
<br />
'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />
<br />
<br />

<br />
<small>''Pic. 11 a and b: Mainboard PGA TT with marked ICs at left picture and changed to 6 sockets right''</small><br />
<br />
<br />
'''2nd step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
Ensure parallel distances to other components.<br />
<br />
If you look from the right between the new sockets and the PGA Speedy, the first contacts are open!<br />
<br />

<br />
<small>''Pic. 11 c: Pin clouseup''</small><br />
<br />
<br />
'''3rd step''': split the /BG signal coming from the CPU. <br />
<br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. <br />
<br />
The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow / copper-coulored at the pictures 12c and 12d) we connect this new signal into the mainboard at the place, shows in the next 4 pictures.<br />

<br />
<small>''Pic. 12 a - d: CPU of PGA TT with divided BG signal''</small><br />
<br />
<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />
<br />
<br />

'''1st step''': remove the old daughterboard, unplug the connector coming from the oscillator and put the old daughterboard to a good place to store them.<br />
<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />

'''Some useful tips for the perfect installation:'''<br />
<br />
# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the CPU and an extension on the TT-RAM connector (e.g. Storm TT or Thunder) and to avoid heat build-up and short circuits.<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily.<br />
# <br />
# If you use a DB Speedy together with a Lightning VME, the connection of the left ribbon cable on the Lightning VME is very tight. Ask Team Thunderstorm to get a specially customized version of the Lighting VME to solve this small problem.<br />

== '''Last steps''' ==<br />
<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />
<br />
After all reassemble the rest of your TT. All work is done. Gratulations!<br />

== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />

<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

<br />
Note: The original CPU continues to be used. However, it gets very hot because of the acceleration and should therefore be cooled.<br />
<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />
<br />

<small>''Pic. 5a and b: Mainboard SMD TT with marked ICs U113 to U116 (=state machine) and after desoldering with new sockets''</small><br />
<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />
<br />

<br />
<small> ''Pic. 6a and b: third and fourth type of patch''</small><br />
<br />
<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />
[[Bild:Abb07a CPU place of SMD TT with divided BG signal.jpg|400px]] [[Bild:Abb07b CPU place of SMD TT with divided BG signal.JPG|400px]] [[Bild:Abb07c_CPU_place_of_SMD_TT_with_divided_BG_signal.JPG|400px]]<br />
<br />
<small>''Pic. 7a - c: new /BG line and optional backup''</small><br />
<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />
<br />

'''4th step''':<br />
After all, put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''5th step''': Put the small connector to all three pins of W101 (if there is a jumper - remove the jumper an plug in the prepared 3 colored cables 1:1 from the Speedy.<br />

<br />
Note: The original CPU is still used. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />
<br />
<br />
Your TT mainboard looks like the next picture. On the next left picture you can see the six ICs. This ist the state machine.<br />
<br />
<br />
'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />
<br />

<br />
<small>''Pic. 11 a and b: Mainboard PGA TT with marked ICs at left picture and changed to 6 sockets right''</small><br />
<br />
<br />
'''2nd step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />

<br />
<small>''Pic. 11 c: Pin clouseup''</small><br />
<br />
<br />
'''3rd step''': split the /BG signal coming from the CPU. <br />
<br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. <br />
<br />
The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow / copper-coulored at the pictures 12c and 12d) we connect this new signal into the mainboard at the place, shows in the next 4 pictures.<br />

<br />
<small>''Pic. 12 a - d: CPU of PGA TT with divided BG signal''</small><br />
<br />
<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />
<br />
<br />

----<br />
<br />
Note: The original CPU should not be used any further. A new CPU with clean pins is required. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />
<br />
<br />
Your TT mainboard looks like the next picture. <br />

<small>''Pic. 16: Mainboard DB TT with marked daughterboard''</small><br />
<br />
<br />
'''1st step''': remove the old daughterboard, unplug the connector coming from the oscillator and put the old daughterboard to a good place to store them.<br />
<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />
<br />
<br />

<br />
<small>''Pic. 17a - b: Coprocessor clock patch made by Atari themselves''</small><br />
<br />
<br />
By a fluke the signal clock line of the coprocessor is cut through via Atari. <br />
<br />
<br />
''' Here are the instructions for the 2nd step: how to patch und connect the clock line between FPU and Speedy in order to clock the FPU with either 16MHz, 32MHz or 48MHz:'''<br />
<br />
# We remove the original black cable between Atari TT Video Shifter and coprocessor and made a new longer cable, connected to the clock pin of the coprocessor. <br />
#<br />
# At the other side of that new cable please solder a female socket pin and connect this socket pin to the back side of DB Speedy.<br />
# <br />
# The next step is, to connect the oscillator plug at the backside of your new DB-Speedy. <br />
# <br />
# Please be sure, that the black cable from oscillator pin seven is connect to the “GND”. <br />

<br />
'''4th step''': Plug in the new 68030 CPU (PGA type, coldcap preferd, it should be a B or C variant with 40 or 50 Mhz, e.g. 68030RC40B)<br />

That´s it!<br />
<br />
<br />
'''Some useful tips for the perfect installation:'''<br />
<br />
# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the CPU and an extension on the TT-RAM connector (e.g. Storm TT or Thunder) and to avoid heat build-up and short circuits.<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily.<br />
# <br />
# If you use a DB Speedy together with a Lightning VME, the connection of the left ribbon cable on the Lightning VME is very tight. Ask Team Thunderstorm to get a specially customized version of the Lighting VME to solve this small problem.<br />

== '''Last steps''' ==<br />
<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />
<br />
After all reassemble the rest of your TT. All work is done. Gratulations!<br />

<br />
* Speedy allows you to speed up your CPU of your Atari TT up to 48 MHz.<br />
* You can speed up your coprocessor (MC68882) of your Atari up to 48 MHz.<br />
* If the increasing of speed doesn’t work inside of your TT, you don’t have to rework all steps! Speedy gives you the item to let them inside of your TT with normal speed.<br />
* You could increase the access to your Alternate-RAM, if you bought the new [https://wiki.newtosworld.de/index.php?title=Storm_-_English_Version STORM TT] Rev. G. If you have an older STORM TT Revision, please make a request to your Thunderstorm Team to change the STORM TT to the newest Revision.<br />

<br />
== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />
<br />
----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

Note: The original CPU continues to be used. However, it gets very hot because of the acceleration and should therefore be cooled.<br />
<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />

<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />

<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />

<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />

Your TT mainboard looks like the next picture. On the next left picture you can see the six ICs. This ist the state machine.<br />
<br />
<br />
'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />

'''3rd step''': split the /BG signal coming from the CPU. <br />
<br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. <br />
<br />
The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow / copper-coulored at the pictures 12c and 12d) we connect this new signal into the mainboard at the place, shows in the next 4 pictures.<br />

<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />

<br />
'''1st step''': remove the old daughterboard, unplug the connector coming from the oscillator and put the old daughterboard to a good place to store them.<br />
<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />

''' Here are the instructions for the 2nd step: how to patch und connect the clock line between FPU and Speedy in order to clock the FPU with either 16MHz, 32MHz or 48MHz:'''<br />
<br />
# We remove the original black cable between Atari TT Video Shifter and coprocessor and made a new longer cable, connected to the clock pin of the coprocessor. <br />
#<br />
# At the other side of that new cable please solder a female socket pin and connect this socket pin to the back side of DB Speedy.<br />
# <br />
# The next step is, to connect the oscillator plug at the backside of your new DB-Speedy. <br />

<br />
'''Some useful tips for the perfect installation:'''<br />
<br />
# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the CPU and an extension on the TT-RAM connector (e.g. Storm TT or Thunder) and to avoid heat build-up and short circuits.<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily.<br />
# <br />
# If you use a DB Speedy together with a Lightning VME, the connection of the left ribbon cable on the Lightning VME is very tight. Ask Team Thunderstorm to get a specially customized version of the Lighting VME to solve this small problem.<br />

== '''Last steps''' ==<br />
<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />
<br />
After all reassemble the rest of your TT. All work is done. Gratulations!<br />

'''First of all: Please be note, that the installation of Speedy needs really advanced skills of soldering! <br />
If you have a novice skill, please ask a competence person for help!'''<br />
<br />
* Speedy allows you to speed up your CPU of your Atari TT up to 48 MHz.<br />
* You can speed up your coprocessor (MC68882) of your Atari up to 48 MHz.<br />
* If the increasing of speed doesn’t work inside of your TT, you don’t have to rework all steps! Speedy gives you the item to let them inside of your TT with normal speed.<br />
* You could increase the access to your Alternate-RAM, if you bought the new [https://wiki.newtosworld.de/index.php?title=Storm_-_English_Version STORM TT] Rev. G. If you have an older STORM TT Revision, please make a request to your Thunderstorm Team to change the STORM TT to the newest Revision.<br />
<br />

<br />
== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />
<br />
----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

<br />
Note: The original CPU continues to be used. However, it gets very hot because of the acceleration and should therefore be cooled.<br />
<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />
<br />

<small>''Pic. 5a and b: Mainboard SMD TT with marked ICs U113 to U116 (=state machine) and after desoldering with new sockets''</small><br />
<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />
<br />

<br />
<small> ''Pic. 6a and b: third and fourth type of patch''</small><br />
<br />
<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />
[[Bild:Abb07a CPU place of SMD TT with divided BG signal.jpg|400px]] [[Bild:Abb07b CPU place of SMD TT with divided BG signal.JPG|400px]] [[Bild:Abb07c_CPU_place_of_SMD_TT_with_divided_BG_signal.JPG|400px]]<br />
<br />
<small>''Pic. 7a - c: new /BG line and optional backup''</small><br />
<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />

'''4th step''':<br />
After all, put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''5th step''': Put the small connector to all three pins of W101 (if there is a jumper - remove the jumper an plug in the prepared 3 colored cables 1:1 from the Speedy.<br />

Your TT mainboard looks like the next picture. On the next left picture you can see the six ICs. This ist the state machine.<br />
<br />
<br />
'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />

<br />
<br />
'''3rd step''': split the /BG signal coming from the CPU. <br />
<br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow / copper-coulored at the pictures 12c and 12d) we connect this new signal into the mainboard at the place, shows in the next 4 pictures.<br />

<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />

<br />
Note: The original CPU should not be used any further. A new CPU with clean pins is required. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />

<br />
<br />
'''1st step''': remove the old daughterboard, unplug the connector coming from the oscillator and put the old daughterboard to a good place to store them.<br />
<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />

<br />
''' Here are the instructions for the 2nd step: how to patch und connect the clock line between FPU and Speedy in order to clock the FPU with either 16MHz, 32MHz or 48MHz:'''<br />
<br />
# We remove the original black cable between Atari TT Video Shifter and coprocessor and made a new longer cable, connected to the clock pin of the coprocessor. <br />
#<br />
# At the other side of that new cable please solder a female socket pin and connect this socket pin to the back side of DB Speedy.<br />
# <br />
# The next step is, to connect the oscillator plug at the backside of your new DB-Speedy. <br />
# <br />
# Please be sure, that the black cable from oscillator pin seven is connect to the “GND”. <br />

<br />
That´s it!<br />
<br />
<br />
'''Some useful tips for the perfect installation:'''<br />
<br />
# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the CPU and an extension on the TT-RAM connector (e.g. Storm TT or Thunder) and to avoid heat build-up and short circuits.<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily.<br />
# <br />
# If you use a DB Speedy together with a Lightning VME, the connection of the left ribbon cable on the Lightning VME is very tight. Ask Team Thunderstorm to get a specially customized version of the Lighting VME to solve this small problem.<br />

== '''Last steps''' ==<br />
<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />
<br />
After all reassemble the rest of your TT. All work is done. Gratulations!<br />

'''First of all: Please be note, that the installation of Speedy needs really advanced skills of soldering! <br />
If you have a novice skill, please ask a competence person for help!'''<br />
<br />
* Speedy allows you to speed up your CPU of your Atari TT up to 48 MHz.<br />
* You can speed up your coprocessor (MC68882) of your Atari up to 48 MHz.<br />
* If the increasing of speed doesn’t work inside of your TT, you don’t have to rework all steps! Speedy gives you the item to let them inside of your TT with normal speed.<br />
* You could increase the access to your Alternate-RAM, if you bought the new [https://wiki.newtosworld.de/index.php?title=Storm_-_English_Version STORM TT] Rev. G. If you have an older STORM TT Revision, please make a request to your Thunderstorm Team to change the STORM TT to the newest Revision.<br />
<br />

<br />
== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />
<br />
----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

<br />
Note: The original CPU continues to be used. However, it gets very hot because of the acceleration and should therefore be cooled.<br />
<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />
<br />

<small>''Pic. 5a and b: Mainboard SMD TT with marked ICs U113 to U116 (=state machine) and after desoldering with new sockets''</small><br />
<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />
<br />

<br />
<small> ''Pic. 6a and b: third and fourth type of patch''</small><br />
<br />
<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />
[[Bild:Abb07a CPU place of SMD TT with divided BG signal.jpg|400px]] [[Bild:Abb07b CPU place of SMD TT with divided BG signal.JPG|400px]] [[Bild:Abb07c_CPU_place_of_SMD_TT_with_divided_BG_signal.JPG|400px]]<br />
<br />
<small>''Pic. 7a - c: new /BG line and optional backup''</small><br />
<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />
<br />

<br />
<br />
'''4th step''':<br />
After all, put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''5th step''': Put the small connector to all three pins of W101 (if there is a jumper - remove the jumper an plug in the prepared 3 colored cables 1:1 from the Speedy.<br />

Note: The original CPU is still used. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />
<br />
<br />
Your TT mainboard looks like the next picture. On the next left picture you can see the six ICs. This ist the state machine.<br />
<br />
<br />
'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />

<br />
<br />
'''3rd step''': split the /BG signal coming from the CPU. <br />
<br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow / copper-coulored at the pictures 12c and 12d) we connect this new signal into the mainboard at the place, shows in the next 4 pictures.<br />

<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />

<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />

<br />
'''Some useful tips for the perfect installation:'''<br />
<br />
# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the CPU and an extension on the TT-RAM connector (e.g. Storm TT or Thunder) and to avoid heat build-up and short circuits.<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily.<br />
# <br />
# If you use a DB Speedy together with a Lightning VME, the connection of the left ribbon cable on the Lightning VME is very tight. Ask Team Thunderstorm to get a specially customized version of the Lighting VME to solve this small problem.<br />

== '''Last steps''' ==<br />
<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />
<br />
After all reassemble the rest of your TT. All work is done. Gratulations!<br />

'''First of all: Please be note, that the installation of Speedy needs really advanced skills of soldering! <br />
If you have a novice skill, please ask a competence person for help!'''<br />
<br />
* Speedy allows you to speed up your CPU of your Atari TT up to 48 MHz.<br />
* You can speed up your coprocessor (MC68882) of your Atari up to 48 MHz.<br />
* If the increasing of speed doesn’t work inside of your TT, you don’t have to rework all steps! Speedy gives you the item to let them inside of your TT with normal speed.<br />
* You could increase the access to your Alternate-RAM, if you bought the new [https://wiki.newtosworld.de/index.php?title=Storm_-_English_Version STORM TT] Rev. G. If you have an older STORM TT Revision, please make a request to your Thunderstorm Team to change the STORM TT to the newest Revision.<br />
<br />

<br />
== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />
<br />
----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

<br />
Note: The original CPU continues to be used. However, it gets very hot because of the acceleration and should therefore be cooled.<br />
<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />
<br />

<br />
<small>''Pic. 5a and b: Mainboard SMD TT with marked ICs U113 to U116 (=state machine) and after desoldering with new sockets''</small><br />
<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />
<br />

<br />
<small> ''Pic. 6a and b: third and fourth type of patch''</small><br />
<br />
<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />
[[Bild:Abb07a CPU place of SMD TT with divided BG signal.jpg|400px]] [[Bild:Abb07b CPU place of SMD TT with divided BG signal.JPG|400px]] [[Bild:Abb07c_CPU_place_of_SMD_TT_with_divided_BG_signal.JPG|400px]]<br />
<br />
<small>''Pic. 7a - c: new /BG line and optional backup''</small><br />
<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />

<br />
<br />
'''4th step''':<br />
After all, put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''5th step''': Put the small connector to all three pins of W101 (if there is a jumper - remove the jumper an plug in the prepared 3 colored cables 1:1 from the Speedy.<br />

<br />
Note: The original CPU is still used. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />
<br />
<br />
Your TT mainboard looks like the next picture. On the next left picture you can see the six ICs. This ist the state machine.<br />
<br />
<br />
'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />
<br />

<br />
<small>''Pic. 11 a and b: Mainboard PGA TT with marked ICs at left picture and changed to 6 sockets right''</small><br />
<br />
<br />

<br />
<small>''Pic. 11 a and b: Mainboard PGA TT with marked ICs at left picture and changed to 6 sockets right''</small><br />
<br />
<br />
'''3rd step''': split the /BG signal coming from the CPU. <br />
<br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow / copper-coulored at the pictures 12c and 12d) we connect this new signal into the mainboard at the place, shows in the next 4 pictures.<br />

<br />
<small>''Abb12a-d: CPU of PGA TT with divided BG signal''</small><br />

<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />

<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />

'''Some useful tips for the perfect installation:'''<br />
<br />
# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the CPU and an extension on the TT-RAM connector (e.g. Storm TT or Thunder) and to avoid heat build-up and short circuits.<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily.<br />
# <br />
# If you use a DB Speedy together with a Lightning VME, the connection of the left ribbon cable on the Lightning VME is very tight. Ask Team Thunderstorm to get a specially customized version of the Lighting VME to solve this small problem.<br />

== '''Last steps''' ==<br />
<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />
<br />
After all reassemble the rest of your TT. All work is done. Gratulations!<br />

<br />
'''First of all: Please be note, that the installation of Speedy needs really advanced skills of soldering! <br />
If you have a novice skill, please ask a competence person for help!'''<br />
<br />
* Speedy allows you to speed up your CPU of your Atari TT up to 48 MHz.<br />
* You can speed up your coprocessor (MC68882) of your Atari up to 48 MHz.<br />
* If the increasing of speed doesn’t work inside of your TT, you don’t have to rework all steps! Speedy gives you the item to let them inside of your TT with normal speed.<br />
* You could increase the access to your Alternate-RAM, if you bought the new [https://wiki.newtosworld.de/index.php?title=Storm_-_English_Version STORM TT] Rev. G. If you have an older STORM TT Revision, please make a request to your Thunderstorm Team to change the STORM TT to the newest Revision.<br />
<br />
<br />
----<br />
<br />
== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />
<br />
----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

----<br />
<br />
Note: The original CPU continues to be used. However, it gets very hot because of the acceleration and should therefore be cooled.<br />
<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />
<br />
[[Bild:Abb04 Mainboard SMD-TT with marked IC.JPG|400px]] [[Bild:Abb05a six new sockets for SMD Speedy.JPG|400px]]<br />
<br />
<small>''Pic. 5a and b: Mainboard SMD TT with marked ICs U113 to U116 (=state machine) and after desoldering with new sockets''</small><br />
<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />
<br />
[[Bild:Abb06_Third_type_of_patch.JPG|400px]] [[Bild:Abb06b_Fourth_type_of_patch.JPG|400px]]<br />
<br />
<small> ''Pic. 6a and b: third and fourth type of patch''</small><br />
<br />
<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />
[[Bild:Abb07a CPU place of SMD TT with divided BG signal.jpg|400px]] [[Bild:Abb07b CPU place of SMD TT with divided BG signal.JPG|400px]] [[Bild:Abb07c_CPU_place_of_SMD_TT_with_divided_BG_signal.JPG|400px]]<br />
<br />
<small>''Pic. 7a - c: new /BG line and optional backup''</small><br />
<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />
<br />

<br />
<small>''Pic 9:SMD TT Mainboard with all changes, ready to install SMD-Speedy, /BG cable is in backup mode at this pic''</small><br />
<br />
<br />
'''4th step''':<br />
After all, put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''5th step''': Put the small connector to all three pins of W101 (if there is a jumper - remove the jumper an plug in the prepared 3 colored cables 1:1 from the Speedy.<br />

<br />
=== '''<big>PGA TT</big>''' ===<br />
----<br />
<br />
Note: The original CPU is still used. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />
<br />
<br />
Your TT mainboard looks like the next picture. On the next left picture you can see the six ICs. This ist the state machine.<br />
<br />
<br />
'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />
<br />
<br />

<br />
<small>''Pic. 11 a and b: Mainboard PGA TT with marked ICs at left picture and changed to 6 sockets right''</small><br />
<br />
<br />
'''2nd step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
<br />

<br />
<small>''Pic. 11 a and b: Mainboard PGA TT with marked ICs at left picture and changed to 6 sockets right''</small><br />
<br />
<br />
'''3rd step''': split the /BG signal coming from the CPU. <br />
<br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow / copper-coulored at the pictures 12c and 12d) we connect this new signal into the mainboard at the place, shows in the next 4 pictures.<br />
<br />

<br />
<small>''Abb12a-d: CPU of PGA TT with divided BG signal''</small><br />
<br />
<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />

=== '''Daughterboard TT''' ===<br />
----<br />
<br />
Note: The original CPU should not be used any further. A new CPU with clean pins is required. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />
<br />
<br />
Your TT mainboard looks like the next picture. <br />

<br />
<small>''Pic. 16: Mainboard DB TT with marked daughterboard''</small><br />
<br />
<br />
'''1st step''': remove the old daughterboard, unplug the connector coming from the oscillator and put the old daughterboard to a good place to store them.<br />
<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />
<br />
<br />

<br />
By a fluke the signal clock line of the coprocessor is cut through via Atari. <br />
<br />
<br />
''' Here are the instructions for the 2nd step: how to patch und connect the clock line between FPU and Speedy in order to clock the FPU with either 16MHz, 32MHz or 48MHz:'''<br />
<br />
# We remove the original black cable between Atari TT Video Shifter and coprocessor and made a new longer cable, connected to the clock pin of the coprocessor. <br />
#<br />
# At the other side of that new cable please solder a female socket pin and connect this socket pin to the back side of DB Speedy.<br />
# <br />
# The next step is, to connect the oscillator plug at the backside of your new DB-Speedy. <br />

The Speedy TT is a small PCB board, which increase the clock speed of the processor (CPU) of an Atari TT. Speedy is available in three different PCBs, depending on your type of mainboard.<br />

<br />
== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />
<br />
----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

<br />
Note: The original CPU continues to be used. However, it gets very hot because of the acceleration and should therefore be cooled.<br />
<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />
<br />

<br />
<small>''Pic. 5a and b: Mainboard SMD TT with marked ICs U113 to U116 (=state machine) and after desoldering with new sockets''</small><br />
<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />
<br />

<br />
<small> ''Pic. 6a and b: third and fourth type of patch''</small><br />
<br />
<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />
[[Bild:Abb07a CPU place of SMD TT with divided BG signal.jpg|400px]] [[Bild:Abb07b CPU place of SMD TT with divided BG signal.JPG|400px]] [[Bild:Abb07c_CPU_place_of_SMD_TT_with_divided_BG_signal.JPG|400px]]<br />
<br />
<small>''Pic. 7a - c: new /BG line and optional backup''</small><br />
<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />
<br />

<small>''Pic 9:SMD TT Mainboard with all changes, ready to install SMD-Speedy, /BG cable is in backup mode at this pic''</small><br />
<br />
<br />
'''4th step''':<br />
After all, put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''5th step''': Put the small connector to all three pins of W101 (if there is a jumper - remove the jumper an plug in the prepared 3 colored cables 1:1 from the Speedy.<br />

<br />
=== '''PGA TT''' ===<br />
----<br />
<br />
Note: The original CPU is still used. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />
<br />
<br />
Your TT mainboard looks like the next picture. On the next left picture you can see the six ICs. This ist the state machine.<br />
<br />
<br />
'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />
<br />
<br />

<br />
<small>''Pic. 11 a and b: Mainboard PGA TT with marked ICs at left picture and changed to 6 sockets right''</small><br />
<br />
<br />
'''2nd step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
<br />

<br />
<small>''Pic. 11 a and b: Mainboard PGA TT with marked ICs at left picture and changed to 6 sockets right''</small><br />
<br />
<br />
'''3rd step''': split the /BG signal coming from the CPU. <br />
<br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow / copper-coulored at the pictures 12c and 12d) we connect this new signal into the mainboard at the place, shows in the next 4 pictures.<br />
<br />

<br />
<small>''Abb12a-d: CPU of PGA TT with divided BG signal''</small><br />
<br />
<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />

=== '''Daughterboard TT''' ===<br />
----<br />
<br />
Note: The original CPU should not be used any further. A new CPU with clean pins is required. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />

<br />
<br />
'''1st step''': remove the old daughterboard, unplug the connector coming from the oscillator and put the old daughterboard to a good place to store them.<br />
<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />
<br />
<br />

<br />
By a fluke the signal clock line of the coprocessor is cut through via Atari. <br />
<br />
<br />
''' Here are the instructions for the 2nd step: how to patch und connect the clock line between FPU and Speedy in order to clock the FPU with either 16MHz, 32MHz or 48MHz:'''<br />
<br />
# We remove the original black cable between Atari TT Video Shifter and coprocessor and made a new longer cable, connected to the clock pin of the coprocessor. <br />
#<br />
# At the other side of that new cable please solder a female socket pin and connect this socket pin to the back side of DB Speedy.<br />
# <br />
# The next step is, to connect the oscillator plug at the backside of your new DB-Speedy. <br />
# <br />
# Please be sure, that the black cable from oscillator pin seven is connect to the “GND”. <br />

<br />
'''Some useful tips for the perfect installation:'''<br />
<br />
# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the CPU and an extension on the TT-RAM connector (e.g. Storm TT or Thunder) and to avoid heat build-up and short circuits.<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily.<br />
# <br />
# If you use a DB Speedy together with a Lightning VME, the connection of the left ribbon cable on the Lightning VME is very tight. Ask Team Thunderstorm to get a specially customized version of the Lighting VME to solve this small problem.<br />

== '''Last steps''' ==<br />
<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />
<br />
After all reassemble the rest of your TT. All work is done. Gratulations!<br />

== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />
<br />
----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

----<br />
<br />
Note: The original CPU continues to be used. However, it gets very hot because of the acceleration and should therefore be cooled.<br />
<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />
<br />

<small>''Pic. 5a and b: Mainboard SMD TT with marked ICs U113 to U116 (=state machine) and after desoldering with new sockets''</small><br />
<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />
<br />

<br />
<small> ''Pic. 6a and b: third and fourth type of patch''</small><br />
<br />
<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />

<br />
<small>''Pic. 7a - c: new /BG line and optional backup''</small><br />
<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />

<br />
<br />
'''4th step''':<br />
After all, put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''5th step''': Put the small connector to all three pins of W101 (if there is a jumper - remove the jumper an plug in the prepared 3 colored cables 1:1 from the Speedy.<br />

=== '''PGA TT''' ===<br />
----<br />
<br />
Note: The original CPU is still used. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />
<br />
<br />
Your TT mainboard looks like the next picture. On the next left picture you can see the six ICs. This ist the state machine.<br />
<br />
<br />
'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />
<br />
<br />

<br />
<small>''Pic. 11 a and b: Mainboard PGA TT with marked ICs at left picture and changed to 6 sockets right''</small><br />
<br />
<br />
'''2nd step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />

<br />
<br />
'''3rd step''': split the /BG signal coming from the CPU. <br />
<br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow / copper-coulored at the pictures 12c and 12d) we connect this new signal into the mainboard at the place, shows in the next 4 pictures.<br />

<br />
<small>''Abb12a-d: CPU of PGA TT with divided BG signal''</small><br />
<br />
<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />

<br />
Note: The original CPU should not be used any further. A new CPU with clean pins is required. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />

<br />
<br />
'''1st step''': remove the old daughterboard, unplug the connector coming from the oscillator and put the old daughterboard to a good place to store them.<br />
<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />
<br />

<small>''Pic. 17a - b: Coprocessor clock patch made by Atari themselves''</small><br />
<br />
<br />
By a fluke the signal clock line of the coprocessor is cut through via Atari. <br />
<br />
<br />
''' Here are the instructions for the 2nd step: how to patch und connect the clock line between FPU and Speedy in order to clock the FPU with either 16MHz, 32MHz or 48MHz:'''<br />
<br />
# We remove the original black cable between Atari TT Video Shifter and coprocessor and made a new longer cable, connected to the clock pin of the coprocessor. <br />
#<br />
# At the other side of that new cable please solder a female socket pin and connect this socket pin to the back side of DB Speedy.<br />
# <br />
# The next step is, to connect the oscillator plug at the backside of your new DB-Speedy. <br />
# <br />
# Please be sure, that the black cable from oscillator pin seven is connect to the “GND”. <br />

<br />
'''Some useful tips for the perfect installation:'''<br />
<br />
# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the CPU and an extension on the TT-RAM connector (e.g. Storm TT or Thunder) and to avoid heat build-up and short circuits.<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily.<br />
# <br />
# If you use a DB Speedy together with a Lightning VME, the connection of the left ribbon cable on the Lightning VME is very tight. Ask Team Thunderstorm to get a specially customized version of the Lighting VME to solve this small problem.<br />

== '''Last steps''' ==<br />
<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />
<br />
After all reassemble the rest of your TT. All work is done. Gratulations!<br />

<br />
* Speedy allows you to speed up your CPU of your Atari TT up to 48 MHz.<br />
* You can speed up your coprocessor (MC68882) of your Atari up to 48 MHz.<br />
* If the increasing of speed doesn’t work inside of your TT, you don’t have to rework all steps! Speedy gives you the item to let them inside of your TT with normal speed.<br />
* You could increase the access to your Alternate-RAM, if you bought the new [https://wiki.newtosworld.de/index.php?title=Storm_-_English_Version STORM TT] Rev. G.

<br />
== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />

----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

=== '''SMD TT''' ===<br />
----<br />
<br />
Note: The original CPU continues to be used. However, it gets very hot because of the acceleration and should therefore be cooled.<br />
<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />
<br />

<small>''Pic. 5a and b: Mainboard SMD TT with marked ICs U113 to U116 (=state machine) and after desoldering with new sockets''</small><br />
<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />
<br />

<br />
<small> ''Pic. 6a and b: third and fourth type of patch''</small><br />
<br />
<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />
[[Bild:Abb07a CPU place of SMD TT with divided BG signal.jpg|400px]] [[Bild:Abb07b CPU place of SMD TT with divided BG signal.JPG|400px]] [[Bild:Abb07c_CPU_place_of_SMD_TT_with_divided_BG_signal.JPG|400px]]<br />
<br />
<small>''Pic. 7a - c: new /BG line and optional backup''</small><br />
<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />
<br />

<small>''Pic 9:SMD TT Mainboard with all changes, ready to install SMD-Speedy, /BG cable is in backup mode at this pic''</small><br />
<br />
<br />
'''4th step''':<br />
After all, put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''5th step''': Put the small connector to all three pins of W101 (if there is a jumper - remove the jumper an plug in the prepared 3 colored cables 1:1 from the Speedy.<br />

That´s it!<br />

<br />
=== '''PGA TT''' ===<br />
----<br />
<br />
Note: The original CPU is still used. It only gets slightly warmer because of the acceleration. Cooling is not absolutely necessary.<br />
<br />
<br />
Your TT mainboard looks like the next picture. On the next left picture you can see the six ICs. This ist the state machine.<br />
<br />
<br />
'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />
<br />
<br />

<br />
<small>''Pic. 11 a and b: Mainboard PGA TT with marked ICs at left picture and changed to 6 sockets right''</small><br />
<br />
<br />
'''2nd step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
<br />

<br />
<small>''Pic. 11 a and b: Mainboard PGA TT with marked ICs at left picture and changed to 6 sockets right''</small><br />
<br />
<br />
'''3rd step''': split the /BG signal coming from the CPU. <br />
<br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow / copper-coulored at the pictures 12c and 12d) we connect this new signal into the mainboard at the place, shows in the next 4 pictures.<br />
<br />

<br />
<small>''Abb12a-d: CPU of PGA TT with divided BG signal''</small><br />
<br />
<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />
<br />

<br />
<br />
'''6th step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />

=== '''Daughterboard TT''' ===<br />
----<br />
<br />
Your TT mainboard looks like the next picture. <br />
<br />

<br />
<small>''Pic. 16: Mainboard DB TT with marked daughterboard''</small><br />
<br />
<br />
'''1st step''': remove the old daughterboard, unplug the connector coming from the oscillator and put the old daughterboard to a good place to store them.<br />
<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />
<br />
<br />
[[Bild:Abb17a_DB-TT_Co-Pro-Patch_01_mod.JPG|400px]] [[Bild:Abb17b_DB-TT_Co-Pro-Patch_02_mod.JPG|400px]] <br />
<br />
<small>''Pic. 17a - b: Coprocessor clock patch made by Atari themselves''</small><br />
<br />
<br />
By a fluke the signal clock line of the coprocessor is cut through via Atari. <br />
<br />
<br />
''' Here are the instructions for the 2nd step: how to patch und connect the clock line between FPU and Speedy in order to clock the FPU with either 16MHz, 32MHz or 48MHz:'''<br />
<br />
# We remove the original black cable between Atari TT Video Shifter and coprocessor and made a new longer cable, connected to the clock pin of the coprocessor. <br />
#<br />
# At the other side of that new cable please solder a female socket pin and connect this socket pin to the back side of DB Speedy.<br />
# <br />
# The next step is, to connect the oscillator plug at the backside of your new DB-Speedy. <br />
# <br />
# Please be sure, that the black cable from oscillator pin seven is connect to the “GND”. <br />
<br />
<br />
Be sure that your changes matched with the next picture.<br />

<small>''Pic. 18: Backside of DB Speedy with clock line to coprocessor and W101 from the oscillator. Both plug at right place under DB Speedy.''</small><br />
<br />
<br />
'''3rd step''': Plug the DB-Speedy into the existing CPU socket. Be careful!<br />
<br />
'''4th step''': Plug in the new 68030 CPU (PGA type, coldcap preferd, it should be a B or C variant with 40 or 50 Mhz, e.g. 68030RC40B)<br />
<br />
<br />
Now the view if all works in the DB TT are finished.<br />

<br />
<br />
That´s it!<br />
<br />
<br />
'''Some useful tips for the perfect installation:'''<br />
<br />
# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the CPU and an extension on the TT-RAM connector (e.g. Storm TT or Thunder) and to avoid heat build-up and short circuits.<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily.<br />
# <br />
# If you use a DB Speedy together with a Lightning VME, the connection of the left ribbon cable on the Lightning VME is very tight. Ask Team Thunderstorm to get a specially customized version of the Lighting VME to solve this small problem.<br />

<br />
== '''Last steps''' ==<br />
<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />
<br />
After all reassemble the rest of your TT. All work is done. Gratulations!<br />

'''First of all: Please be note, that the installation of Speedy needs really advanced skills of soldering! <br />
If you have a novice skill, please ask a competence person for help!'''<br />
<br />
* Speedy allows you to speed up your CPU of your Atari TT up to 48 MHz.<br />
* You can speed up your coprocessor (MC68882) of your Atari up to 48 MHz.<br />
* If the increasing of speed doesn’t work inside of your TT, you don’t have to rework all steps! Speedy gives you the item to let them inside of your TT with normal speed.<br />
* You could increase the access to your Alternate-RAM, if you bought the new [https://wiki.newtosworld.de/index.php?title=Storm_-_English_Version STORM TT] Rev. G. If you have an older STORM TT Revision, please make a request to your Thunderstorm Team to change the STORM TT to the newest Revision.<br />
<br />
<br />

<br />
== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />
<br />
----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

----<br />
<br />
Note: The original CPU continues to be used. However, it gets very hot because of the acceleration and should therefore be cooled.<br />
<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />
<br />

<small>''Pic. 5a and b: Mainboard SMD TT with marked ICs U113 to U116 (=state machine) and after desoldering with new sockets''</small><br />
<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />
<br />

<br />
<small> ''Pic. 6a and b: third and fourth type of patch''</small><br />
<br />
<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />
[[Bild:Abb07a CPU place of SMD TT with divided BG signal.jpg|400px]] [[Bild:Abb07b CPU place of SMD TT with divided BG signal.JPG|400px]] [[Bild:Abb07c_CPU_place_of_SMD_TT_with_divided_BG_signal.JPG|400px]]<br />
<br />
<small>''Pic. 7a - c: new /BG line and optional backup''</small><br />
<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />

=== '''PGA TT''' ===<br />
----<br />
<br />
Your TT mainboard looks like the next picture. On the next left picture you can see the six ICs. This ist the state machine.<br />
<br />
<br />
'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />
<br />
<br />

<br />
<br />
'''2nd step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />

<br />
<small>''Pic. 11 a and b: Mainboard PGA TT with marked ICs at left picture and changed to 6 sockets right''</small><br />
<br />
<br />
'''3rd step''': split the /BG signal coming from the CPU. <br />
<br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow / copper-coulored at the pictures 12c and 12d) we connect this new signal into the mainboard at the place, shows in the next 4 pictures.<br />
<br />

<br />
<small>''Abb12a-d: CPU of PGA TT with divided BG signal''</small><br />
<br />
<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />

<br />
Your TT mainboard looks like the next picture. <br />

<br />
<small>''Pic. 16: Mainboard DB TT with marked daughterboard''</small><br />
<br />
<br />
'''1st step''': remove the old daughterboard, unplug the connector coming from the oscillator and put the old daughterboard to a good place to store them.<br />
<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />
<br />
<br />

<br />
<small>''Pic. 17a - b: Coprocessor clock patch made by Atari themselves''</small><br />
<br />
<br />
By a fluke the signal clock line of the coprocessor is cut through via Atari. <br />
<br />
<br />
''' Here are the instructions for the 2nd step: how to patch und connect the clock line between FPU and Speedy in order to clock the FPU with either 16MHz, 32MHz or 48MHz:'''<br />
<br />
# We remove the original black cable between Atari TT Video Shifter and coprocessor and made a new longer cable, connected to the clock pin of the coprocessor. <br />
#<br />
# At the other side of that new cable please solder a female socket pin and connect this socket pin to the back side of DB Speedy.<br />
# <br />
# The next step is, to connect the oscillator plug at the backside of your new DB-Speedy. <br />
# <br />
# Please be sure, that the black cable from oscillator pin seven is connect to the “GND”. <br />
<br />
<br />
Be sure that your changes matched with the next picture.<br />

<small>''Pic. 18: Backside of DB Speedy with clock line to coprocessor and W101 from the oscillator. Both plug at right place under DB Speedy.''</small><br />
<br />
<br />
'''3rd step''': Plug the DB-Speedy into the existing CPU socket. Be careful!<br />
<br />
'''4th step''': Plug in the new 68030 CPU (PGA type, coldcap preferd, it should be a B or C variant with 40 or 50 Mhz, e.g. 68030RC40B)<br />
<br />
<br />
Now the view if all works in the DB TT are finished.<br />

<br />
<br />
That´s it!<br />
<br />
<br />
'''Some useful tips for the perfect installation:'''<br />
<br />
# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the CPU and an extension on the TT-RAM connector (e.g. Storm TT or Thunder) and to avoid heat build-up and short circuits.<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily.<br />
# <br />
# If you use a DB Speedy together with a Lightning VME, the connection of the left ribbon cable on the Lightning VME is very tight. Ask Team Thunderstorm to get a specially customized version of the Lighting VME to solve this small problem.<br />

<br />
== '''Last steps''' ==<br />
<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />
<br />
After all reassemble the rest of your TT. All work is done. Gratulations!<br />

'''First of all: Please be note, that the installation of Speedy needs really advanced skills of soldering! <br />
If you have a novice skill, please ask a competence person for help!'''<br />
<br />
* Speedy allows you to speed up your CPU of your Atari TT up to 48 MHz.<br />
* You can speed up your coprocessor (MC68882) of your Atari up to 48 MHz.<br />
* If the increasing of speed doesn’t work inside of your TT, you don’t have to rework all steps! Speedy gives you the item to let them inside of your TT with normal speed.<br />
* You could increase the access to your Alternate-RAM, if you bought the new [https://wiki.newtosworld.de/index.php?title=Storm_-_English_Version STORM TT] Rev. G. If you have an older STORM TT Revision, please make a request to your Thunderstorm Team to change the STORM TT to the newest Revision.<br />
<br />
<br />

<br />
== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />
<br />
----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

=== '''SMD TT''' ===<br />
----<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />
<br />

<br />
<small>''Pic. 5a and b: Mainboard SMD TT with marked ICs U113 to U116 (=state machine) and after desoldering with new sockets''</small><br />
<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />
<br />

<br />
<small> ''Pic. 6a and b: third and fourth type of patch''</small><br />
<br />
<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />
[[Bild:Abb07a CPU place of SMD TT with divided BG signal.jpg|400px]] [[Bild:Abb07b CPU place of SMD TT with divided BG signal.JPG|400px]] [[Bild:Abb07c_CPU_place_of_SMD_TT_with_divided_BG_signal.JPG|400px]]<br />
<br />
<small>''Pic. 7a - c: new /BG line and optional backup''</small><br />
<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />
<br />

<br />
<br />
'''4th step''':<br />
After all, put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''5th step''': Put the small connector to all three pins of W101 (if there is a jumper - remove the jumper an plug in the prepared 3 colored cables 1:1 from the Speedy.<br />

=== '''PGA TT''' ===<br />
----<br />
<br />
Your TT mainboard looks like the next picture. On the next left picture you can see the six ICs. This ist the state machine.<br />
<br />
<br />
'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />
<br />
<br />

<br />
<small>''Pic. 11 a and b: Mainboard PGA TT with marked ICs at left picture and changed to 6 sockets right''</small><br />
<br />
<br />
'''2nd step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />

<br />
<small>''Pic. 11 a and b: Mainboard PGA TT with marked ICs at left picture and changed to 6 sockets right''</small><br />
<br />
<br />
'''3rd step''': split the /BG signal coming from the CPU. <br />
<br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow / copper-coulored at the pictures 12c and 12d) we connect this new signal into the mainboard at the place, shows in the next 4 pictures.<br />

<br />
<small>''Abb12a-d: CPU of PGA TT with divided BG signal''</small><br />
<br />
<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />

<br />
<br />
'''1st step''': remove the old daughterboard, unplug the connector coming from the oscillator and put the old daughterboard to a good place to store them.<br />
<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />

<br />
By a fluke the signal clock line of the coprocessor is cut through via Atari. <br />
<br />
<br />
''' Here are the instructions for the 2nd step: how to patch und connect the clock line between FPU and Speedy in order to clock the FPU with either 16MHz, 32MHz or 48MHz:'''<br />
<br />
# We remove the original black cable between Atari TT Video Shifter and coprocessor and made a new longer cable, connected to the clock pin of the coprocessor. <br />
#<br />
# At the other side of that new cable please solder a female socket pin and connect this socket pin to the back side of DB Speedy.<br />
# <br />
# The next step is, to connect the oscillator plug at the backside of your new DB-Speedy. <br />
# <br />
# Please be sure, that the black cable from oscillator pin seven is connect to the “GND”. <br />

<br />
'''3rd step''': Plug the DB-Speedy into the existing CPU socket. Be careful!<br />
<br />
'''4th step''': Plug in the new 68030 CPU (PGA type, coldcap preferd, it should be a B or C variant with 40 or 50 Mhz, e.g. 68030RC40B)<br />
<br />
<br />
Now the view if all works in the DB TT are finished.<br />

<br />
That´s it!<br />
<br />
<br />
'''Some useful tips for the perfect installation:'''<br />
<br />
# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the CPU and an extension on the TT-RAM connector (e.g. Storm TT or Thunder) and to avoid heat build-up and short circuits.<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily.<br />
# <br />
# If you use a DB Speedy together with a Lightning VME, the connection of the left ribbon cable on the Lightning VME is very tight. Ask Team Thunderstorm to get a specially customized version of the Lighting VME to solve this small problem.<br />

<br />
== '''Last steps''' ==<br />
<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />
<br />
After all reassemble the rest of your TT. All work is done. Gratulations!<br />

'''First of all: Please be note, that the installation of Speedy needs really advanced skills of soldering! <br />
If you have a novice skill, please ask a competence person for help!'''<br />
<br />
* Speedy allows you to speed up your CPU of your Atari TT up to 48 MHz.<br />
* You can speed up your coprocessor (MC68882) of your Atari up to 48 MHz.<br />
* If the increasing of speed doesn’t work inside of your TT, you don’t have to rework all steps! Speedy gives you the item to let them inside of your TT with normal speed.<br />
* You could increase the access to your Alternate-RAM, if you bought the new [https://wiki.newtosworld.de/index.php?title=Storm_-_English_Version STORM TT] Rev. G. If you have an older STORM TT Revision, please make a request to your Thunderstorm Team to change the STORM TT to the newest Revision.<br />
<br />
<br />
----<br />
<br />
== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />
<br />
----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

=== '''SMD TT''' ===<br />
----<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />
<br />

<br />
<small>''Pic. 5a and b: Mainboard SMD TT with marked ICs U113 to U116 (=state machine) and after desoldering with new sockets''</small><br />
<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />
<br />
[[Bild:Abb06_Third_type_of_patch.JPG|400px]] [[Bild:Abb06b_Fourth_type_of_patch.JPG|400px]]<br />
<br />
<small> ''Pic. 6a and b: third and fourth type of patch''</small><br />
<br />
<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />
[[Bild:Abb07a CPU place of SMD TT with divided BG signal.jpg|400px]] [[Bild:Abb07b CPU place of SMD TT with divided BG signal.JPG|400px]] [[Bild:Abb07c_CPU_place_of_SMD_TT_with_divided_BG_signal.JPG|400px]]<br />
<br />
<small>''Pic. 7a - c: new /BG line and optional backup''</small><br />
<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />
<br />

<small>''Pic 9:SMD TT Mainboard with all changes, ready to install SMD-Speedy, /BG cable is in backup mode at this pic''</small><br />
<br />
<br />
'''4th step''':<br />
After all, put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''5th step''': Put the small connector to all three pins of W101 (if there is a jumper - remove the jumper an plug in the prepared 3 colored cables 1:1 from the Speedy.<br />

That´s it!<br />
<br />

<br />
=== '''PGA TT''' ===<br />
----<br />
<br />
Your TT mainboard looks like the next picture. On the next left picture you can see the six ICs. This ist the state machine.<br />
<br />
<br />
'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />
<br />
<br />

<br />
<small>''Pic. 11 a and b: Mainboard PGA TT with marked ICs at left picture and changed to 6 sockets right''</small><br />
<br />
<br />
'''2nd step''': split the /BG signal coming from the CPU. <br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow at the picture) we connect this new signal into the mainboard at the place, shows in the next 3 pictures.<br />
<br />

<br />
<small>''Abb12a-d: CPU of PGA TT with divided BG signal''</small><br />
<br />
<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''3rd step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />

<br />
<br />
'''6th step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''7th step''': put the small adapter between W101 (mainboard) and W101 (Speedy).<br />
<br />
<br />
That´s it!<br />
<br />

<br />
=== '''Daughterboard TT''' ===<br />
----<br />
<br />
Your TT mainboard looks like the next picture. <br />
<br />

<br />
<small>''Pic. 16: Mainboard DB TT with marked daughterboard''</small><br />
<br />
<br />
'''1st step''': remove the old daughterboard, unplug the connector coming from the oscillator and put the old daughterboard to a good place to store them.<br />
<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />
<br />
<br />

<br />
<small>''Pic. 17a - b: Coprocessor clock patch made by Atari themselves''</small><br />
<br />
<br />
By a fluke the signal clock line of the coprocessor is cut through via Atari. <br />
<br />
<br />
''' Here are the instructions for the 2nd step: how to patch und connect the clock line between FPU and Speedy in order to clock the FPU with either 16MHz, 32MHz or 48MHz:'''<br />
<br />
# We remove the original black cable between Atari TT Video Shifter and coprocessor and made a new longer cable, connected to the clock pin of the coprocessor. <br />
#<br />
# At the other side of that new cable please solder a female socket pin and connect this socket pin to the back side of DB Speedy.<br />
# <br />
# The next step is, to connect the oscillator plug at the backside of your new DB-Speedy. <br />
# <br />
# Please be sure, that the black cable from oscillator pin seven is connect to the “GND”. <br />

'''4th step''': Plug in the new 68030 CPU (PGA type, coldcap preferd, it should be a B or C variant with 40 or 50 Mhz, e.g. 68030RC40B)<br />
<br />
<br />

<br />
That´s it!<br />
<br />
<br />
'''Some useful tips for the perfect installation:'''<br />
<br />
# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the CPU and an extension on the TT-RAM connector (e.g. Storm TT or Thunder) and to avoid heat build-up and short circuits.<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily.<br />
# <br />
# If you use a DB Speedy together with a Lightning VME, the connection of the left ribbon cable on the Lightning VME is very tight. Ask Team Thunderstorm to get a specially customized version of the Lighting VME to solve this small problem.<br />

== '''Last steps''' ==<br />
<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />
<br />
After all reassemble the rest of your TT. All work is done. Gratulations!<br />

<br />
'''First of all: Please be note, that the installation of Speedy needs really advanced skills of soldering! <br />
If you have a novice skill, please ask a competence person for help!'''<br />
<br />
* Speedy allows you to speed up your CPU of your Atari TT up to 48 MHz.<br />
* You can speed up your coprocessor (MC68882) of your Atari up to 48 MHz.<br />
* If the increasing of speed doesn’t work inside of your TT, you don’t have to rework all steps! Speedy gives you the item to let them inside of your TT with normal speed.<br />
* You could increase the access to your Alternate-RAM, if you bought the new [https://wiki.newtosworld.de/index.php?title=Storm_-_English_Version STORM TT] Rev. G. If you have an older STORM TT Revision, please make a request to your Thunderstorm Team to change the STORM TT to the newest Revision.<br />
<br />
<br />
----<br />
<br />
== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />
<br />
----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

<br />
<br />
<br />
<br />
<br />
----<br />
=== '''SMD TT''' ===<br />
----<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />
<br />
[[Bild:Abb04 Mainboard SMD-TT with marked IC.JPG|400px]] [[Bild:Abb05a six new sockets for SMD Speedy.JPG|400px]]<br />
<br />
<small>''Pic. 5a and b: Mainboard SMD TT with marked ICs U113 to U116 (=state machine) and after desoldering with new sockets''</small><br />
<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />
<br />
[[Bild:Abb06_Third_type_of_patch.JPG|400px]] [[Bild:Abb06b_Fourth_type_of_patch.JPG|400px]]<br />
<br />
<small> ''Pic. 6a and b: third and fourth type of patch''</small><br />
<br />
<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />
[[Bild:Abb07a CPU place of SMD TT with divided BG signal.jpg|400px]] [[Bild:Abb07b CPU place of SMD TT with divided BG signal.JPG|400px]] [[Bild:Abb07c_CPU_place_of_SMD_TT_with_divided_BG_signal.JPG|400px]]<br />
<br />
<small>''Pic. 7a - c: new /BG line and optional backup''</small><br />
<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />
<br />

<br />
<small>''Pic. 8: Speedy with female socket under the PCB for injecting the /BG signal from the CPU''</small><br />

<br />
Be sure that all your changes matched with the next picture.<br />

<br />
<small>''Pic 9:SMD TT Mainboard with all changes, ready to install SMD-Speedy, /BG cable is in backup mode at this pic''</small><br />
<br />
<br />
'''4th step''':<br />
After all, put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''5th step''': Put the small connector to all three pins of W101 (if there is a jumper - remove the jumper an plug in the prepared 3 colored cables 1:1 from the Speedy.<br />
<br />

<br />
That´s it!<br />
<br />
<br />
<br />
----<br />
<br />
=== '''PGA TT''' ===<br />
----<br />
<br />
Your TT mainboard looks like the next picture. On the next left picture you can see the six ICs. This ist the state machine.<br />
<br />
<br />
'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />
<br />
<br />
[[Bild:Abb11a PGA TT state machine.jpg|400px]] [[Bild:Abb11b PGA TT state machine entfernt und gesockelt.jpg|400px]] <br />
<br />
<small>''Pic. 11 a and b: Mainboard PGA TT with marked ICs at left picture and changed to 6 sockets right''</small><br />
<br />
<br />
'''2nd step''': split the /BG signal coming from the CPU. <br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow at the picture) we connect this new signal into the mainboard at the place, shows in the next 3 pictures.<br />
<br />

<br />
<small>''Abb12a-d: CPU of PGA TT with divided BG signal''</small><br />
<br />
<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''3rd step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />
<br />
[[Bild:Abb14_Cable_between_R61_and_U701_Pin1.JPG|400px]] <br />
<br />
<small>''Abb14: Cable between R61 and U704 Pin 1''</small><br />

<br />
<small>''Abb15: PGA TT Mainboard with all changes, ready to install PGA-Speedy''</small><br />
<br />
<br />
'''6th step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''7th step''': put the small adapter between W101 (mainboard) and W101 (Speedy).<br />
<br />
<br />
That´s it!<br />
<br />
<br />
<br />
----<br />
<br />
=== '''Daughterboard TT''' ===<br />
----<br />
<br />
Your TT mainboard looks like the next picture. <br />
<br />
[[Bild:Abb16_Mainboard_DB_TT_with_marked_Daughterboard.JPG|400px]]<br />
<br />
<small>''Pic. 16: Mainboard DB TT with marked daughterboard''</small><br />
<br />
<br />
'''1st step''': remove the old daughterboard, unplug the connector coming from the oscillator and put the old daughterboard to a good place to store them.<br />
<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />
<br />
<br />
[[Bild:Abb17a_DB-TT_Co-Pro-Patch_01_mod.JPG|400px]] [[Bild:Abb17b_DB-TT_Co-Pro-Patch_02_mod.JPG|400px]] <br />
<br />
<small>''Pic. 17a - b: Coprocessor clock patch made by Atari themselves''</small><br />
<br />
<br />
By a fluke the signal clock line of the coprocessor is cut through via Atari. <br />
<br />
<br />
''' Here are the instructions for the 2nd step: how to patch und connect the clock line between FPU and Speedy in order to clock the FPU with either 16MHz, 32MHz or 48MHz:'''<br />
<br />
# We remove the original black cable between Atari TT Video Shifter and coprocessor and made a new longer cable, connected to the clock pin of the coprocessor. <br />
#<br />
# At the other side of that new cable please solder a female socket pin and connect this socket pin to the back side of DB Speedy.<br />
# <br />
# The next step is, to connect the oscillator plug at the backside of your new DB-Speedy. <br />
# <br />
# Please be sure, that the black cable from oscillator pin seven is connect to the “GND”. <br />
<br />
<br />
Be sure that your changes matched with the next picture.<br />
<br />

<br />
<small>''Pic. 18: Backside of DB Speedy with clock line to coprocessor and W101 from the oscillator. Both plug at right place under DB Speedy.''</small><br />
<br />
<br />
'''3rd step''': Plug the DB-Speedy into the existing CPU socket. Be careful!<br />
<br />
'''4th step''': Plug in the new 68030 CPU (PGA type, coldcap preferd, it should be a B or C variant with 40 or 50 Mhz, e.g. 68030RC40B)<br />
<br />
<br />
Now the view if all works in the DB TT are finished.<br />

<br />
<br />
That´s it!<br />
<br />
<br />
'''Some useful tips for the perfect installation:'''<br />
<br />
# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the CPU and an extension on the TT-RAM connector (e.g. Storm TT or Thunder) and to avoid heat build-up and short circuits.<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily.<br />
# <br />
# If you use a DB Speedy together with a Lightning VME, the connection of the left ribbon cable on the Lightning VME is very tight. Ask Team Thunderstorm to get a specially customized version of the Lighting VME to solve this small problem.<br />

<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />

* If the increasing of speed doesn’t work inside of your TT, you don’t have to rework all steps! Speedy gives you the item to let them inside of your TT with normal speed.<br />
* You could increase the access to your Alternate-RAM, if you bought the new [https://wiki.newtosworld.de/index.php?title=Storm_-_English_Version STORM TT] Rev. G. If you have an older STORM TT Revision, please make a request to your Thunderstorm Team to change the STORM TT to the newest Revision.<br />
<br />
<br />
----<br />
<br />
== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />
<br />
----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

----<br />
=== '''SMD TT''' ===<br />
----<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />
<br />
[[Bild:Abb04 Mainboard SMD-TT with marked IC.JPG|400px]] [[Bild:Abb05a six new sockets for SMD Speedy.JPG|400px]]<br />
<br />
<small>''Pic. 5a and b: Mainboard SMD TT with marked ICs U113 to U116 (=state machine) and after desoldering with new sockets''</small><br />
<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />
<br />
[[Bild:Abb06_Third_type_of_patch.JPG|400px]] [[Bild:Abb06b_Fourth_type_of_patch.JPG|400px]]<br />
<br />
<small> ''Pic. 6a and b: third and fourth type of patch''</small><br />
<br />
<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />
[[Bild:Abb07a CPU place of SMD TT with divided BG signal.jpg|400px]] [[Bild:Abb07b CPU place of SMD TT with divided BG signal.JPG|400px]] [[Bild:Abb07c_CPU_place_of_SMD_TT_with_divided_BG_signal.JPG|400px]]<br />
<br />
<small>''Pic. 7a - c: new /BG line and optional backup''</small><br />
<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />
<br />

<br />
<small>''Pic 9:SMD TT Mainboard with all changes, ready to install SMD-Speedy, /BG cable is in backup mode at this pic''</small><br />
<br />
<br />
'''4th step''':<br />
After all, put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''5th step''': Put the small connector to all three pins of W101 (if there is a jumper - remove the jumper an plug in the prepared 3 colored cables 1:1 from the Speedy.<br />
<br />

<br />
That´s it!<br />
<br />
<br />
<br />
----<br />
<br />
=== '''PGA TT''' ===<br />
----<br />
<br />
Your TT mainboard looks like the next picture. On the next left picture you can see the six ICs. This ist the state machine.<br />
<br />
<br />
'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />
<br />
<br />
[[Bild:Abb11a PGA TT state machine.jpg|400px]] [[Bild:Abb11b PGA TT state machine entfernt und gesockelt.jpg|400px]] <br />
<br />
<small>''Pic. 11 a and b: Mainboard PGA TT with marked ICs at left picture and changed to 6 sockets right''</small><br />
<br />
<br />
'''2nd step''': split the /BG signal coming from the CPU. <br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow at the picture) we connect this new signal into the mainboard at the place, shows in the next 3 pictures.<br />
<br />

<br />
<small>''Abb12a-c: CPU of PGA TT with divided BG signal''</small><br />
<br />
<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''3rd step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />
<br />

<br />
<small>''Abb15: PGA TT Mainboard with all changes, ready to install PGA-Speedy''</small><br />
<br />
<br />
'''6th step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''7th step''': put the small adapter between W101 (mainboard) and W101 (Speedy).<br />
<br />
<br />
That´s it!<br />
<br />
<br />
<br />
----<br />
<br />
=== '''Daughterboard TT''' ===<br />
----<br />
<br />
Your TT mainboard looks like the next picture. <br />
<br />
[[Bild:Abb16_Mainboard_DB_TT_with_marked_Daughterboard.JPG|400px]]<br />
<br />
<small>''Pic. 16: Mainboard DB TT with marked daughterboard''</small><br />
<br />
<br />
'''1st step''': remove the old daughterboard, unplug the connector coming from the oscillator and put the old daughterboard to a good place to store them.<br />
<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />
<br />
<br />
[[Bild:Abb17a_DB-TT_Co-Pro-Patch_01_mod.JPG|400px]] [[Bild:Abb17b_DB-TT_Co-Pro-Patch_02_mod.JPG|400px]] <br />
<br />
<small>''Pic. 17a - b: Coprocessor clock patch made by Atari themselves''</small><br />
<br />
<br />
By a fluke the signal clock line of the coprocessor is cut through via Atari. <br />
<br />
<br />
''' Here are the instructions for the 2nd step: how to patch und connect the clock line between FPU and Speedy in order to clock the FPU with either 16MHz, 32MHz or 48MHz:'''<br />
<br />
# We remove the original black cable between Atari TT Video Shifter and coprocessor and made a new longer cable, connected to the clock pin of the coprocessor. <br />
#<br />
# At the other side of that new cable please solder a female socket pin and connect this socket pin to the back side of DB Speedy.<br />
# <br />
# The next step is, to connect the oscillator plug at the backside of your new DB-Speedy. <br />
# <br />
# Please be sure, that the black cable from oscillator pin seven is connect to the “GND”. <br />
<br />
<br />
Be sure that your changes matched with the next picture.<br />
<br />

<br />
<small>''Pic. 18: Backside of DB Speedy with clock line to coprocessor and W101 from the oscillator. Both plug at right place under DB Speedy.''</small><br />
<br />
<br />
'''3rd step''': Plug the DB-Speedy into the existing CPU socket. Be careful!<br />
<br />
'''4th step''': Plug in the new 68030 CPU (PGA type, coldcap preferd, it should be a B or C variant with 40 or 50 Mhz, e.g. 68030RC40B)<br />
<br />
<br />
Now the view if all works in the DB TT are finished.<br />

<br />
<br />
That´s it!<br />
<br />
<br />
'''Some useful tips for the perfect installation:'''<br />
<br />
# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the CPU and an extension on the TT-RAM connector (e.g. Storm TT or Thunder) and to avoid heat build-up and short circuits.<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily.<br />
# <br />
# If you use a DB Speedy together with a Lightning VME, the connection of the left ribbon cable on the Lightning VME is very tight. Ask Team Thunderstorm to get a specially customized version of the Lighting VME to solve this small problem.<br />
<br />

<br />
== '''Last steps''' ==<br />
<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />
<br />
After all reassemble the rest of your TT. All work is done. Gratulations!<br />

The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />
<br />
----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

=== '''SMD TT''' ===<br />
----<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />
<br />

<br />
<small>''Pic. 5a and b: Mainboard SMD TT with marked ICs U113 to U116 (=state machine) and after desoldering with new sockets''</small><br />
<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />
<br />

<br />
<small> ''Pic. 6a and b: third and fourth type of patch''</small><br />
<br />
<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />
[[Bild:Abb07a CPU place of SMD TT with divided BG signal.jpg|400px]] [[Bild:Abb07b CPU place of SMD TT with divided BG signal.JPG|400px]] [[Bild:Abb07c_CPU_place_of_SMD_TT_with_divided_BG_signal.JPG|400px]]<br />
<br />
<small>''Pic. 7a - c: new /BG line and optional backup''</small><br />
<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />
<br />

<small>''Pic 9:SMD TT Mainboard with all changes, ready to install SMD-Speedy, /BG cable is in backup mode at this pic''</small><br />
<br />
<br />
'''4th step''':<br />
After all, put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''5th step''': Put the small connector to all three pins of W101 (if there is a jumper - remove the jumper an plug in the prepared 3 colored cables 1:1 from the Speedy.<br />

That´s it!<br />
<br />

<br />
=== '''PGA TT''' ===<br />
----<br />
<br />
Your TT mainboard looks like the next picture. On the next left picture you can see the six ICs. This ist the state machine.<br />
<br />
<br />
'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />
<br />
<br />
[[Bild:Abb11a PGA TT state machine.jpg|400px]] [[Bild:Abb11b PGA TT state machine entfernt und gesockelt.jpg|400px]] <br />
<br />
<small>''Pic. 11 a and b: Mainboard PGA TT with marked ICs at left picture and changed to 6 sockets right''</small><br />
<br />
<br />
'''2nd step''': split the /BG signal coming from the CPU. <br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow at the picture) we connect this new signal into the mainboard at the place, shows in the next 3 pictures.<br />
<br />

<br />
<small>''Abb12a-c: CPU of PGA TT with divided BG signal''</small><br />
<br />
<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''3rd step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />
<br />

<br />
<br />
'''6th step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''7th step''': put the small adapter between W101 (mainboard) and W101 (Speedy).<br />
<br />
<br />
That´s it!<br />
<br />
<br />

<br />
=== '''Daughterboard TT''' ===<br />
----<br />
<br />
Your TT mainboard looks like the next picture. <br />
<br />

<br />
<small>''Pic. 16: Mainboard DB TT with marked daughterboard''</small><br />
<br />
<br />
'''1st step''': remove the old daughterboard, unplug the connector coming from the oscillator and put the old daughterboard to a good place to store them.<br />
<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />
<br />
<br />
[[Bild:Abb17a_DB-TT_Co-Pro-Patch_01_mod.JPG|400px]] [[Bild:Abb17b_DB-TT_Co-Pro-Patch_02_mod.JPG|400px]] <br />
<br />
<small>''Pic. 17a - b: Coprocessor clock patch made by Atari themselves''</small><br />
<br />
<br />
By a fluke the signal clock line of the coprocessor is cut through via Atari. <br />
<br />
<br />
''' Here are the instructions for the 2nd step: how to patch und connect the clock line between FPU and Speedy in order to clock the FPU with either 16MHz, 32MHz or 48MHz:'''<br />
<br />
# We remove the original black cable between Atari TT Video Shifter and coprocessor and made a new longer cable, connected to the clock pin of the coprocessor. <br />
#<br />
# At the other side of that new cable please solder a female socket pin and connect this socket pin to the back side of DB Speedy.<br />
# <br />
# The next step is, to connect the oscillator plug at the backside of your new DB-Speedy. <br />
# <br />
# Please be sure, that the black cable from oscillator pin seven is connect to the “GND”. <br />
<br />
<br />
Be sure that your changes matched with the next picture.<br />
<br />

<br />
<small>''Pic. 18: Backside of DB Speedy with clock line to coprocessor and W101 from the oscillator. Both plug at right place under DB Speedy.''</small><br />
<br />
<br />
'''3rd step''': Plug the DB-Speedy into the existing CPU socket. Be careful!<br />
<br />
'''4th step''': Plug in the new 68030 CPU (PGA type, coldcap preferd, it should be a B or C variant with 40 or 50 Mhz, e.g. 68030RC40B)<br />
<br />
<br />
Now the view if all works in the DB TT are finished.<br />

<br />
<br />
<br />
'''Some useful tips for the perfect installation:'''<br />
<br />
# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the CPU and an extension on the TT-RAM connector (e.g. Storm TT or Thunder) and to avoid heat build-up and short circuits.<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily.<br />
# <br />
# If you use a DB Speedy together with a Lightning VME, the connection of the left ribbon cable on the Lightning VME is very tight. Ask Team Thunderstorm to get a specially customized version of the Lighting VME to solve this small problem.<br />
<br />

<br />
That´s it!<br />
<br />

<br />
----<br />
<br />
== '''Last steps''' ==<br />
<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />
<br />
After all reassemble the rest of your TT. All work is done. Gratulations!<br />

<br />
* Speedy allows you to speed up your CPU of your Atari TT up to 48 MHz.<br />
* You can speed up your coprocessor (MC68882) of your Atari up to 48 MHz.<br />
* If the increasing of speed doesn’t work inside of your TT, you don’t have to rework all steps! Speedy gives you the item to let them inside of your TT with normal speed.<br />
* You could increase the access to your Alternate-RAM, if you bought the new [https://wiki.newtosworld.de/index.php?title=Storm_-_English_Version STORM TT] Rev. G.

== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />
<br />
----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket.

Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />

<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />
<br />

<br />
<small> ''Pic. 6a and b: third and fourth type of patch''</small><br />
<br />
<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />
[[Bild:Abb07a CPU place of SMD TT with divided BG signal.jpg|400px]] [[Bild:Abb07b CPU place of SMD TT with divided BG signal.JPG|400px]] [[Bild:Abb07c_CPU_place_of_SMD_TT_with_divided_BG_signal.JPG|400px]]<br />
<br />
<small>''Pic. 7a - c: new /BG line and optional backup''</small><br />
<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />

<br />
<br />
'''4th step''':<br />
After all, put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''5th step''': Put the small connector to all three pins of W101 (if there is a jumper - remove the jumper an plug in the prepared 3 colored cables 1:1 from the Speedy.<br />

=== '''PGA TT''' ===<br />
----<br />
<br />
Your TT mainboard looks like the next picture. On the next left picture you can see the six ICs. This ist the state machine.<br />
<br />
<br />
'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />
<br />
<br />

<br />
<small>''Pic. 11 a and b: Mainboard PGA TT with marked ICs at left picture and changed to 6 sockets right''</small><br />
<br />
<br />
'''2nd step''': split the /BG signal coming from the CPU. <br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow at the picture) we connect this new signal into the mainboard at the place, shows in the next 3 pictures.<br />

<br />
<small>''Abb12a-c: CPU of PGA TT with divided BG signal''</small><br />
<br />
<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''3rd step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />
<br />

<br />
'''6th step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''7th step''': put the small adapter between W101 (mainboard) and W101 (Speedy).<br />

<br />
That´s it!<br />

=== '''Daughterboard TT''' ===<br />
----<br />
<br />
Your TT mainboard looks like the next picture. <br />
<br />

<br />
<small>''Pic. 16: Mainboard DB TT with marked daughterboard''</small><br />
<br />
<br />
'''1st step''': remove the old daughterboard, unplug the connector coming from the oscillator and put the old daughterboard to a good place to store them.<br />
<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />
<br />
<br />
[[Bild:Abb17a_DB-TT_Co-Pro-Patch_01_mod.JPG|400px]] [[Bild:Abb17b_DB-TT_Co-Pro-Patch_02_mod.JPG|400px]] <br />
<br />
<small>''Pic. 17a - b: Coprocessor clock patch made by Atari themselves''</small><br />
<br />
<br />
By a fluke the signal clock line of the coprocessor is cut through via Atari. <br />
<br />
<br />
''' Here are the instructions for the 2nd step: how to patch und connect the clock line between FPU and Speedy in order to clock the FPU with either 16MHz, 32MHz or 48MHz:'''<br />
<br />
# We remove the original black cable between Atari TT Video Shifter and coprocessor and made a new longer cable, connected to the clock pin of the coprocessor. <br />
#<br />
# At the other side of that new cable please solder a female socket pin and connect this socket pin to the back side of DB Speedy.<br />
# <br />
# The next step is, to connect the oscillator plug at the backside of your new DB-Speedy. <br />
# <br />
# Please be sure, that the black cable from oscillator pin seven is connect to the “GND”. <br />
<br />
<br />
Be sure that your changes matched with the next picture.<br />

<small>''Pic. 18: Backside of DB Speedy with clock line to coprocessor and W101 from the oscillator. Both plug at right place under DB Speedy.''</small><br />
<br />
<br />
'''3rd step''': Plug the DB-Speedy into the existing CPU socket. Be careful!<br />
<br />
'''4th step''': Plug in the new 68030 CPU (PGA type, coldcap preferd, it should be a B or C variant with 40 or 50 Mhz, e.g. 68030RC40B)<br />
<br />
<br />
Now the view if all works in the DB TT are finished.<br />

<br />
<br />
<br />
'''Some useful tips for the perfect installation:'''<br />
<br />
# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the CPU and an extension on the TT-RAM connector (e.g. Storm TT or Thunder) and to avoid heat build-up and short circuits.<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily.<br />
# <br />
# If you use a DB Speedy together with a Lightning VME, the connection of the left ribbon cable on the Lightning VME is very tight. Ask Team Thunderstorm to get a specially customized version of the Lighting VME to solve this small problem.<br />
<br />

<br />
== '''Last steps''' ==<br />
<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />
<br />
After all reassemble the rest of your TT. All work is done. Gratulations!<br />

'''First of all: Please be note, that the installation of Speedy needs really advanced skills of soldering! <br />
If you have a novice skill, please ask a competence person for help!'''<br />
<br />
* Speedy allows you to speed up your CPU of your Atari TT up to 48 MHz.<br />
* You can speed up your coprocessor (MC68882) of your Atari up to 48 MHz.<br />
* If the increasing of speed doesn’t work inside of your TT, you don’t have to rework all steps! Speedy gives you the item to let them inside of your TT with normal speed.<br />
* You could increase the access to your Alternate-RAM, if you bought the new [https://wiki.newtosworld.de/index.php?title=Storm_-_English_Version STORM TT] Rev. G. If you have an older STORM TT Revision, please make a request to your Thunderstorm Team to change the STORM TT to the newest Revision.<br />
<br />
<br />

<br />
== '''Technical Details''' ==<br />
<br />
The data bus inside of all TT is depending of a 16 MHz bus speed. Atari decided short time for delivery of the first Atari-TTs to speed them up to 32 MHz. That means, that the CPU is clocked with a 32 MHz clock and the bus still driven by 16 MHz. The matching of these two clock cycles realized with two PAL/GALs (U111 and U112) and four 74F74 (U113 up to U116) inside of all TTs. In this explanation we say to this six ICs: “state machine”. The designation of these parts is in all sort of TTs the same one.<br />
<br />
''By the way: The daughterboard TT is the oldest version of mainboard. There you can see, that the TT was designed only for 16 MHz bus clock speed and 16 MHz processor clock speed. To increase the clock speed of the processor Atari made a PCB which handle this. This is the daughterboard. ☺ And the six ICs (U111 – U116) placed onto the daughterboard! The next generation of TTs is the “PGA version”. Same state machine, but now the state machine and processor are placed onto the mainboard. To reduce costs, inside the newest and latest version of TTs, Atari replace the PGA CPU at the mainboard with a SMD CPU.''<br />
<br />
Speedy replace the old state machine (remember: U111 – U116) and establish a new once, which allows us together with a PLL circuit to increase the processor speed at triple bus speed (3 x 16 MHz = 48 MHz).<br />
<br />
To implement Speedy inside of your TT it is necessary to unsolder the old state machine. This means that you have to desolder the six ICs U111 to U116 in the version with PGA CPU and SMD CPU!<br />
<br />
Another item in this case is, that the /BG (Bus Grant) signal inside of the Atari TT designed for a 16 MHz clock bus transfer. The timing match also, if the processor get an increased clock speed of 32 MHz. <br />
<br />
Above 32 MHz this timing doesn’t matched together. The /BG signal from the CPU is to quick to recognized at the mainboard. The activation of this signal could get lost between processor and mainboard. It’s incessant to split the /BG signal and loop it through the Speedy PCB. Speedy adapt the correct timing of the /BG signal, if the CPU is driven with 48 MHz clock speed. To split the /BG signal and to inject the new /BG signal into the mainboard is a second part, what we shall to do.<br />
<br />
Depending of your Type of mainboard this means more or less work. If you have a daughterboard TT, it’s quite simple, because these six ICs are on the daughterboard and there is no /BG patch required here! If you have a PGA or SMD version, it’s hard work!<br />
<br />
Additionally, Speedy needs the both clocks (16 MHz and 32 MHz) of the mainboard. Both are easily available at the Jumper W101. W101 normally get the opportunity to switch the clock speed of the coprocessor. We use this jumper W101 to get these both clocks for Speedy. We connect all three pins of W101 to Speedy. In the pictures of the PGA Speedy and the SMD Speedy you can see the cables from/to W101. The advantage now is, that we could offer the coprocessor 16 MHz, 32 MHz and also 48 MHz, depending which clock speed will accept from the coprocessor.<br />
<br />
The procedure to prepare your TT is in all cases technical the same! The steps could look a bit different.<br />
<br />
<br />
<br />
----<br />
== '''Installation''' ==<br />
<br />
Remove all connections to and from the Atari. All work is done without power.<br />
<br />
Open your TT and take the mainboard out of the case. Note the loss of warranty!<br />
<br />
'''Some useful tips that you should take to heart:'''<br />
<br />
* make some notes or picture of all additional part inside of your TT, which give you a good way to reassemble after all your TT in right order<br />
* always be very careful, pay attention to correct polarity, correct fit, check all connections several times, usually a small cause has a big effect<br />
* do not destroy the IC's, especially the PAL's from the state machine or have spares to test the TT before installing the Speedy or to revert to original spec<br />
* for PGA Sppedy and SMD Speedy: remove the VME PCB first (if possible) to add plenty of working room <br />
* for PGA Speedy and SMD Speedy: when desoldering the state machine please pay extra attention to the ground and vcc pins (7&14 10&20), they are tough to desolder <br />
* for PGA Speedy and SMD Speedy: First place the new sockets correctly on the Speedy and then place the assembly with the socket pins on the mainboard. This way it is easier to find the cleared vias in the mainboard and the Speedy also "automatically" aligns itself in the socket. Alternativ: socket 1-2 IC's at a time and test inbetween sessions to reduce the amount of searching/debugging if the TT doesn' t work after socketing or <br />

----<br />
<br />
'''1st step''':<br />
Your TT mainboard looks like the next picture. On the next picture you can see the six ICs which you have to unsolder and before that insert 6 new sockets: 4 pieces with contacts and 2 pieces with 20 contacts.<br />
<br />
<br />

<br />
<br />
'''2nd step''':<br />
Depending of your Revision of mainboard, you have to '''remove the clock patch of the processor clock'''. <br />
<br />
Atari did some clock patches inside some TT’s to optimize the clock trace of the processor: <br />
<br />
* First type is, “no clock patch”. Easy: Only removing the six ICs is necessary. <br />
<br />
* Second type of patch is a cable connected from U110 Pin 1 to resistor (R888).<br />
<br />
* Third type of patch is a cable between R997 and R888.<br />
<br />
* Fourth type of patch is a cable connected from R997 to U210 (74AC244) Pin 17 and a second cable connected from U210 Pin 3 to resistor (R888).<br />
<br />

<br />
<small> ''Pic. 6a and b: third and fourth type of patch''</small><br />
<br />
<br />
In case of the both last tree patches you remove all cables and replace the resistor R888 (10 Ohm) onto of the marked place at the mainboard without the cables.<br />
<br />
<br />
'''3rd step''':<br />
Split the /BG signal coming from the CPU. For this you have to cut through the signal line onto the mainboard close to the CPU. The next picture shows a good place to divide the signal line of /BG signal.<br />
<br />
[[Bild:Abb07a CPU place of SMD TT with divided BG signal.jpg|400px]] [[Bild:Abb07b CPU place of SMD TT with divided BG signal.JPG|400px]] [[Bild:Abb07c_CPU_place_of_SMD_TT_with_divided_BG_signal.JPG|400px]]<br />
<br />
<small>''Pic. 7a - c: new /BG line and optional backup''</small><br />
<br />
<br />
/BG signal coming from the CPU get a small cable, which shall connect to Speedy. To fall back in the old situation, it is useful to install also a female socket pin on the opposite side of /BG signal. There you have every time the opportunity to jumper the /BG signal in old situation.<br />
<br />
Connect the /BG signal from CPU into the free female socket pin under the Speedy PCB. Additional information: The new /BG signal from Speedy goes via U112 Pin 11 into the mainboard. There is nothing to do.<br />

'''4th step''':<br />
After all, put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''5th step''': Put the small connector to all three pins of W101 (if there is a jumper - remove the jumper an plug in the prepared 3 colored cables 1:1 from the Speedy.<br />

'''1st step''': unsolder these six ICs U111 - U116 carefully and solder 6 new sockets therefor as shown at the next right picture. Please remeber the tips no. 5 and 6 in section "Installation"!<br />
<br />

<br />
<br />
'''2nd step''': split the /BG signal coming from the CPU. <br />
<br />
The cut through of the /BG signal is into the PGA TT another one like in the SMD TT! This is be dept in case, that the place, where we can easily divide the /BG signal inside of the PGA TT is another place like into the SMD TT.<br />
<br />
In the PGA TT the /BG signal line connect in normal way to Pin 11 of U112. So, the /BG signal of the CPU inject the Speedy at this pin. The new /BG signal for the mainboard connected at the female socket pin onto the Speedy. Over a small cable (yellow at the picture) we connect this new signal into the mainboard at the place, shows in the next 3 pictures.<br />

<br />
<br />
Optional: To fall back in the old situation, you put the other end of the (yellow) cable instead of the Speedy to Pin 11 of U112. <br />
<br />
<br />
'''3rd step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''4th step''': put the small connector to all three pins of W101. The marked cable is connected to Pin 1 of W101.<br />
<br />
'''5th step''': change the signal line of the signal /AS (address-strobe). This step is only for PGA TTs relevant! Unfortunately, we found out, that the place where Atari inject this signal into the mainboard (U112 Pin 18) isn’t the best choice to reach the best signal trace. In order to this reason it is quite useful to inject the signal at U704 Pin 1. Please have a look to the next picture.<br />

<br />
<br />
'''6th step''': put Speedy on top of the sockets of U111 up to U116. Please be careful and check that all pins fit correctly into the right socket pins.<br />
<br />
'''7th step''': put the small adapter between W101 (mainboard) and W101 (Speedy).<br />

=== '''Daughterboard TT''' ===<br />
----<br />
<br />
Your TT mainboard looks like the next picture. <br />
<br />

<br />
<small>''Pic. 16: Mainboard DB TT with marked daughterboard''</small><br />
<br />
<br />
'''1st step''': remove the old daughterboard, unplug the connector coming from the oscillator and put the old daughterboard to a good place to store them.<br />
<br />
'''2nd step''': build new the signal line for the clock speed from the coprocessor. <br />
<br />
<br />
FYI: Atari delivered the first daughterboard TT with fix 16 MHz coprocessor clock speed. The last daughterboard TT fix by Atari themselves under the mainboard to 32 MHz clock speed. <br />
<br />
Both solution are fixed solution without any jumper! <br />
<br />
Remember please, that W101 inside of the daughterboard TT has only two instead of three pins like in the other TTs! The next picture show the 32 MHz clock speed patch for the coprocessor.<br />
<br />
<br />
[[Bild:Abb17a_DB-TT_Co-Pro-Patch_01_mod.JPG|400px]] [[Bild:Abb17b_DB-TT_Co-Pro-Patch_02_mod.JPG|400px]] <br />
<br />
<small>''Pic. 17a - b: Coprocessor clock patch made by Atari themselves''</small><br />
<br />
<br />
By a fluke the signal clock line of the coprocessor is cut through via Atari. <br />
<br />
<br />
''' Here are the instructions for the 2nd step: how to patch und connect the clock line between FPU and Speedy in order to clock the FPU with either 16MHz, 32MHz or 48MHz:'''<br />
<br />
# We remove the original black cable between Atari TT Video Shifter and coprocessor and made a new longer cable, connected to the clock pin of the coprocessor. <br />
#<br />
# At the other side of that new cable please solder a female socket pin and connect this socket pin to the back side of DB Speedy.<br />
# <br />
# The next step is, to connect the oscillator plug at the backside of your new DB-Speedy. <br />
# <br />
# Please be sure, that the black cable from oscillator pin seven is connect to the “GND”. <br />
<br />
<br />
Be sure that your changes matched with the next picture.<br />

<br />
<small>''Pic. 18: Backside of DB Speedy with clock line to coprocessor and W101 from the oscillator. Both plug at right place under DB Speedy.''</small><br />
<br />
<br />
'''3rd step''': Plug the DB-Speedy into the existing CPU socket. Be careful!<br />
<br />
'''4th step''': Plug in the new 68030 CPU (PGA type, coldcap preferd, it should be a B or C variant with 40 or 50 Mhz, e.g. 68030RC40B)<br />
<br />
<br />
Now the view if all works in the DB TT are finished.<br />

<br />
<br />
<br />
'''Some useful tips for the perfect installation:'''<br />
<br />
# Plug in an extra VG96 connector (prefered: ERNI 224412, 3x32 pins with long gold contacts) to get enough distance between the CPU and an extension on the TT-RAM connector (e.g. Storm TT or Thunder) and to avoid heat build-up and short circuits.<br />
# <br />
# If you use an extra VG96 socket as well as a (Turbo)Thunder and a StormTT, use PS/2 RAM modules with a maximum height of 3cm in the Storm TT. Otherwise the original case will no longer fit. 4cm high RAM modules do not fit. As a rule, RAM modules are 2 or 3 cm high - this fits easily.<br />
# <br />
# If you use a DB Speedy together with a Lightning VME, the connection of the left ribbon cable on the Lightning VME is very tight. Ask Team Thunderstorm to get a specially customized version of the Lighting VME to solve this small problem.<br />
<br />

== '''Last steps''' ==<br />
<br />
Connect the power supply and the VGA monitor to the mainboard of your TT and test your mainboard. Please check all details and make the first start of your TT. If the start screen apply, you have finished your conversion job!<br />
<br />
Next step is to find out, which clock speed your Co-processor tolerate. At delivery time the Speedy is configured to 32 MHz coprocessor clock speed. Change the Jumper 1 and 2 in right order onto your Speedy to increase or decrease the speed of your coprocessor.<br />
<br />
After all reassemble the rest of your TT. All work is done. Gratulations!<br />
