Yeah, Snooper has a nubus card that checks all
voltages etc. with leds.
I guess a DMM and a nubus pinout would be as useful if not more so. At
least on the PC side, the 'diagnostic cards' tend to just have an LED and
resistor from each power line to ground. So if the line is low, but not
missing (say the +5V line is sitting at 4.2V or something), the LED still
lights.
Does the ADB have a fuse?
Heh, about time to try swapping in a known good IIfx motherboard. ;)
Or actually fixing the problem properly by making some measurements and
finding what's failed rather than replacing random parts until the fault
goes away. As I've said before, this is no way to fix anything, certainly
not a computer!
