Just like me, my first-rev PC-6001 RAM/ROM expander cartridge looks good but doesn't work. I think I've missed shorting the MSW1/MSW2 jumper that keeps the computer from working if it's open and the cartridge is detected. Hopefully an easy bodge and then I can enjoy Extended BASIC. #retrocomputing#pc6001#kicad
