All Power Macintosh G3 Models | All 1998 Models | Dynamically Compare This Mac to Others

Apple Power Mac G3 The Apple Power Macintosh G3/266 All-in-One -- based on the compact Gossamer architecture and codenamed Artemis -- features a 266 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 (after May 1, 1998) graphics acceleration with 2 MB of VRAM (expandable to 6 MB), and the "Wings personality card" with audio and video input/output -- all packed into an easily expandable all-in-one case. Custom configurations also were available.

Like all other Power Macintosh G3 models, the Power Macintosh G3/266 All-in-One uses the "third-generation" (G3) PowerPC 750 processor with a "backside" level 2 cache for a substantial performance boost compared to earlier systems using a "lookaside" level 2 cache.

The Power Macintosh G3/266 All-in-One is identical to the entry-level Power Macintosh G3/233 All-in-One except the "G3/266" model has a faster processor and the "Wings personality card" which provides S-video and composite input/output ports.

Both Power Macintosh G3 "All-in-One" models were sold exclusively to the education market and were not offered at all outside of North America.

Despite the age of this system, site sponsor Other World Computing has RAM, hard drives, SSDs, and other upgrades available for this specific Mac while supplies last.
