The Apple Power Macintosh G3/300 Desktop, based on the compact Gossamer architecture, features a 300 MHz PowerPC 750 (G3) processor with 1 MB of backside cache, 32 MB or 64 MB of RAM, a 6.0 GB hard drive, a 24X CD-ROM drive, an internal Zip 100 drive, ATI 3D Rage II+, Rage Pro (starting May 1, 1998), or Rage Pro Turbo (starting August 12, 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.
The Power Macintosh G3/300 Desktop was available by build-to-order from March 17, 1998 to July 7, 1998 and re-introduced as a standard configuration on August 12, 1998 (M7105LL/A).
Custom configuration options included an Ultra/Wide SCSI hard drive, internal DVD-ROM drive, 10/100Base-T Ethernet, superior graphics, and a Firewire card among others.
