Power Macintosh G3 (Desktop)

Introduced: November 1997
Terminated: January 1999


Running the new G3 PowerPC 750 processor at 233, 266 or 300Mhz, the Power Macintosh G3 desktop had a 4 or 6Gb hard drive.  It had a 24x CD-ROM, a DVD-ROM, a 1.4 floppy drive and an optional Zip drive.  It shipped with the AppleDesign Keyboard and the ADB Mouse II.  It had a maximum RAM of 768Mb.  There was a graphics card, three PCI slots, one PERCH slots and two expansion bays for SCSI devices.  It had analog audio inputs/outputs and optional RCA stereo jacks.  It also had a built-in speaker.


The G3 desktop came in a case similar to the 7300.  This was not as expandable as the G3 MiniTower model.  The G3s became new Macintosh speed champs with the PowerPC 750 processor.  The G3 was originally designed so that it would be compatible with any OS that could support it.  This, like the Apple clones produced earlier, was an attempt to gain more market share.  The idea was scrapped when Steve Jobs returned to Apple and saw the way the Apple clones had negatively impacted profits.

  • Great! I like this packed of data you put up on this page. I’ve been studying Apple’s products most likely their current innovations but flashing back about their history computers sounds so interesting. GAR Labs
