    Replacing Power Mac G3 motherboard with one from G4?

    Hello, some time ago I posted about my Power Mac G3 (B&W), which appeared to have a broken motherboard. I unfortunately wasn't able to repair it. That leaves me with a non-functional G3 and not a lot of options. I could buy a replacement board or another G3, but those are getting more rare and...

    Using ATX PSU with beige G3?

    Hi, I just recently got a beige G3 desktop, but the power supply seems to be dying. I heard that these support ATX PSUs but I'm still not entirely sure.

    "Bus error" bomb screen when trying to boot Mac OS 9.1 or later on a Power Macintosh G3 Minitower

    I've been trying to get the latest version of Mac OS 9 (9.2.2) working on my beige Power Macintosh G3 (Minitower 266 MHz). However, there's an issue I've been encountering with all versions from 9.1 onward. The OS won't boot. The "Starting Up..." progress bar gets about a tenth of the way full...

    Power Mac G3 B&W Chimes but no video

    Hi, I recently got a B&W tower PowerMac G3 (don't know exactly which model) without DVD reader and HDD. I powered it and saw a grey screen with a folder and a question mark followed by the finder logo. Probably couldn't find OS X (duh). At least it booted. I powered it off, got a OS X Tiger...
