Do you guys know if an old Sawtooth Powermac G4 has a plug for an older 15" plastic flat ADC Studio Display? Not the older display with the round plastic stand, the type with the flat plastic sides, from about year 2000-2003. Thanks. Unsure of how they plug into those older machines. Also, is that machine worth anything functionally? I need a machine that will boot both OS9 and 10 for a beginniner.
