Basically, I need to fit all my Macs on one desk, so I'm wondering if I could just use the iMac G3 as a monitor to my PowerMac? They're the 1998 models, maybe a year or so off. While I'm at it, my PowerPC desktop?
yes, but you would need to build some sort of vga to old style mac monitor cable, believe it or not the imac g3's are monitors with a logic board built in the screen plugs into the logic board with the monitor connector used on old macs
