Hey! I think I have the same problem, but I don't have a diagnostic rom, or anything to actually find out. What troubleshooting steps should I take, I'm kind of lost here. Should I change out the multiplexers? I was not able to find the ones you were using though.
Those keyboards are awful. The little pads loose connectivity over time. Also, alignment must be perfect, otherwise some keys will not work. Crappy 100%
Which EProm did you use? I think it's a 128k but it has 28 pins. I have some 264k which have 32 pins so technically I guess I could make an adapter but would prefer to have the right 28 pin chip.
Nice Keyboard Cable and good WORK !!
Wow! Looks great. You make it look easy.
I certainly do appreciate it!
Nice video!
