The PSU is known good, I have not done a PRAM reset but I believe the bus clocks are different from the card to the motherboard, and that's probably what's tripping it up
A few months ago, I was trying to overclock my MDD (rev A from 2002) from 1.25GHz to 1.5GHz, so I could get DiscordPPC to run properly, but I accidentally overvolted the CPU card and killed the logic board. Can this logic board be saved or should I just buy a working one?
the 040 LCs don't need more oomph. Byte Knight (the sysop of CQII) put an LC 475 logic board inside an LC III, and it has worked with the LC III's power supply
AFAIK, the power supplies from all pizza box LC machines are interchangeable. I have an LC III that has a power supply that has the same model number as the power supply of an LC II
As i was looking at my LC III today, I found out there’s some unused pads for a ROM of an unknown capacity, then I remembered the rominator ii and Macintosh classic which both had bootable systems in rom that were accessed by pressing or holding keys on startup. Would that be possible to make on...
I have a 1.25GHz MDD dual CPU card from a rev a MDD from 2002 that I blew up due to over voltage. Does anyone have any spare 7455s or 7457s I can use to put on the card? Thanks in advance
