Arduino PS/2 mouse and joystick adapter for Commodore CDTV
This project aims to read data from a PS/2 mouse and a normal Amiga/Atari/C64 joystick and translate it to the weird serial protocol that the Commodore CDTV uses.
- Single Arduino .ino file, without any dependencies. Easy peasy.
- Utilises hardware features as much as possible. Robust design.
- At the time of writing, probably not working very well. Untested with a proper CDTV (mine is still in storage). Looks good on my scope though :)
