Apple Power Macintosh G3 300 Minitower Specs (M6572LL/A*)
Power Macintosh G3 Main | Ports | Support Links | Q&A | Forums
The Apple Power Macintosh G3/300 Minitower, based on the compact Gossamer architecture, features a 300 MHz PowerPC 750 (G3) processor with 1 MB of backside cache, 64 MB or 128 MB of RAM, a 4.0 GB or 8.0 GB hard drive, a 24X CD-ROM drive, ATI 3D Rage II+ or Rage Pro (starting May 1, 1998), or Rage Pro Turbo (after August 12, 1998) graphics acceleration with 6 MB of VRAM (some configurations offer additional VRAM on a PCI card), and either the "Whisper personality card" with audio input/output or the "Wings personality card" with audio/video input/output -- all packed into an easily expandable minitower 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.
There were at least three different "standard" configurations of the Power Macintosh G3/300 Minitower -- the original version (M6572LL/A) equipped with 64 MB of RAM, a single 4 GB Ultra/Wide SCSI hard drive, and 6 MB of VRAM for US$3399. A second original configuration (M6494LL/A) was configured with 128 MB of RAM, dual 4 GB Ultra/Wide SCSI hard drives, 6 MB of VRAM installed onboard and an additional 8 MB of VRAM on a 2D/3D graphics PCI card, dual display support, and both 10Base-T and 10/100Base-T Ethernet for US$4599.
The second model (M7247LL/A) -- introduced August 12, 1998 -- shipped with a single 8 GB IDE/ATA-2 hard drive, a Zip drive, Rage Pro Turbo graphics with 6 MB of VRAM and the "Wings personality card" with audio and video input/output for US$2399. Custom configurations also were available.
