I am looking for a motherboard and possibly processor for a MDD g4 powermac. I need the 167mhz version, rev with dual firewire 400 ports. Also, possibly a dual 1.25ghz processor module. I have either a dead processor or motherboard in this machine and I am having trouble finding some used replacement parts. Any help on where to find or anyone have one? THe problem is that you turn on the computer, no startup up chime, then a few seconds later, the fans kick up to full speed and it just sits there, no video, red light on motherboard, pmu reset doesnt do anything, tried new battery, video card is good. Any help would be appreciated.
