Power Macintosh G3 (Blue and White)

Introduced: January 1999
Terminated: September 1999


The Blue and White Power Macintosh G3 was available in a variety of configurations.  They were all housed in a new tower-style case that used the same translucent plastic as the iMac and iBook line.  It ran the PowerPC 750 chip at speeds of between 300-400Mhz.  There was a maximum RAM of 1Gb.  The hard drive was available with between 6-12Gb of space.  A Zip drive was available and it came with either a 32x CD-ROM, a 5x DVD-ROM or DVD-RAM.  It was the first Apple to feature FireWire ports in addition to the USB ports.  It had four PCI expansion slots and three or four internal drive bays.


The Blue and White G3 was very different from its beige predecessor.  It was the first high-end Mac to have USB ports and it was the first Apple to have FireWire ports.  It eliminated several older industry standards like serial ports, a floppy drive and on-board SCSI.  The various configurations ranged in price from $1599 at the low end to $5000 at the high end.
