Another #AppleLisaClone update! You’ll remember I was debugging my new #AppleLisa breakout board. I was getting strange behavior: system would boot only once when cold, reboots after would hang and not progress to POST.
I focused most of my time on my board. Cutting traces, bodging, testing. Nothing was improving.
It wasn’t until I put in a new CPU card when things suddenly began working 100%!
Soft power, floppy, Mac keyboard input all working! 😎
