Overview =
The Lightning ST is a pcb with various items for all ATARI ST models.
The pcb give you the opportunity to add
- two USB 1.1 compatible ports
- an IDE interface
- an adressdecoder for TOS2.06 (hexE00000) (further instructions see below).
The main IC on the pcb is a XC95144XL from Xilinx. The USB-Ports based on a ISP1160 chip from NXP.
The IDE interface offer three operate modi:
- Falcon compatible modus
- byteswap modus with twisted cable (solution like ppera it use)
- last but not least a smart swap modus (recommed mode for best speed and compatibility).
The IDE interface also could be disabled by not setting any jumper (J1 and J2 open). With this three operate modi fully compatibility to other pcbs warranted.

Rear view, oblique and top view of the jumper.
Side view. The missing pin is for your orientation.
The assignment of the two USB ports is standardized and labeled. Note the coding pin when connecting the cable to the USB bracket.
The Lightning ST provides a decoder for using a modern OS (TOS 2.06, EmuTOS) via pins 11 and 12. Ideal is the connection to the Cloudy.
Software installtion
Pictures
DOM and USB Braket connected (here with CPU on the Lightning ST)
64 pin DIL socket on top of an 68000 CPU to "open the bus for the tower of babel".
Instead of the socket you can also solder a Cloudy to the pins of the CPU, this saves space upwards.
You can also unsolder the CPU, solder a socket for it and then put the CPU on top - as you like!
But: Always pay attention to the correct alignment!
You can change the order if you want. Its a modular system.
You can run the Lighnting ST alone or together with a Cloudy or together with a Storm ST or together with Cloudy and Storm ST - just as you like and need it!
Do you see the difference when using the TOS decoder?
Using the decoder from the Storm ST has the advantage that you don't have to carry a ROM2 signal from the mainboard to the Lightning ST.
So this is the preferred variant, because you only have to connect the INT signal to the Lighnting ST to use the IDE port!
What a sight: Complete expansion from bottom to top: CPU, socket, Lightning ST, Cloudy, Storm ST and RTC
With this modular tower you get: one IDE port, two USB ports, TOS Decoder, two flashable Operating systems, 8 MB FastRAM, Realtime clock
