    I've recently acquired a B&W Rev.B Power Mac G3. I used to have one back in the day, and wanted to relive some memories. I know these machines can sometimes behave in wired ways, but after going through many troubleshooting procedures I'm honestly out of ideas. I bought it, but due to covid...

    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...
