I have got a visitor: a dead CBM 4040 disk drive. The symptoms: all LEDs stuck on. No disk activity. This means the 6502 does not boot correctly.
First checks: voltages are correct, reset is working,...
So, the CBM 4040 is running again. Can you guess what it was? If ALL the chips except for the RIOT and CPU and the OneROM have been pulled, what could prevent the machine from booting??
