Desoldered [[ASICACID]] chip from [[User:Fano| Fano]]'s cartridge (thanks, Fano), attached to PC's parallel printer port:
ACID PC
CLK ---- Strobe
A0..A7 ---- Data 0..7
GND,5V ---- GND,5V

For curiosity, here's the original source code used for reverse-engineering. It's barely commented or user-friendly.

This is original circuit, assembled while I was visiting my parents. I couldn't find a 36pin centronics socket, only a (very) old 25pin RS232 cable, so I needed to use that.

When I came back home, I wrecked the original circuit, and made a miniaturized adapter with robust centronics socket. Not that I'd still really needed it, - I've been already done with the rev engineering at that time - I just didndon't like messy cables. [[Category:CPC Plus]][[Category:Cartridges| ]][[Category:DIY]][[Category:CPC History]]
