• Speedy allows you to speed up your CPU of your Atari TT up to 48 MHz.
• You can speed up your coprocessor (MC68882) of your Atari up to 48 MHz.
• 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.
• You could increase the access to your Alternate-RAM, if you bought the new 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.
