Apple Power Mac G3The Apple Power Macintosh G3/233 Desktop, based on the compact Gossamer architecture, features a 233 MHz PowerPC 750 (G3) processor with 512k of backside cache, 32 MB of RAM, a 4.0 GB hard drive, a 24X CD-ROM drive, ATI 3D Rage II+ or Rage Pro (starting May 1, 1998) graphics acceleration with 2 MB of VRAM (expandable to 6 MB), and the standard "Whisper personality card" with audio input/output -- all packed into an easily expandable desktop case.

The Power Macintosh G3 models were the first Apple Macs to use the "third-generation" (G3) PowerPC 750 processor which also unveiled a new "backside" level 2 cache for a substantial performance boost compared to earlier systems using a "lookaside" level 2 cache. Custom configuration options included an Ultra/Wide SCSI hard drive, internal DVD-ROM drive, internal Zip drive, 10/100Base-T Ethernet, superior graphics, and a Firewire card, among others.
