I was able to jumpstart it and get the arpeggio death chime, but then it suddenly switched off. No pop, no burning smell, no magic smoke, simply off. After that, no amount of jumpstarting the first pin of the power supply (white wire) will power the machine on. I checked and there are no scorch...

I just got my Mac II to fire up, but now I need to diagnose it due to getting a death chime. The only Mac monitor I have supports a fixed rate of 832 x 624. The original Macintosh II Video Card installed has all VRAM sockets filled, so my understanding is that it supports 8-bit color at 640 x...
