Apple Power Macintosh G3 266 Minitower Specs (M6142LL/A*)
Power Macintosh G3 Main | Ports | Support Links | Q&A | Forums
The Apple Power Macintosh G3/266 Minitower, based on the compact Gossamer architecture, features a 266 MHz PowerPC 750 (G3) processor with 512k of backside cache, 32 MB or 128 MB of RAM, a 4.0 GB or 6.0 GB hard drive, a 24X CD-ROM drive, ATI 3D Rage II+ or Rage Pro (starting May 1, 1998) graphics acceleration with 2 MB or 6 MB of VRAM, 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 two different "standard" configurations of the Power Macintosh G3/266 Minitower -- the original version (M6142LL/A) with 32 MB of RAM, a 6 GB IDE hard drive, 2 MB of VRAM, a Zip drive, S-video and composite video input/output ports (Wings) for US$3000, and the second version (M6459LL/A) -- added January 6, 1998 -- with 128 MB of RAM, a 4 GB Ultra/Wide SCSI hard drive, 6 MB of VRAM installed on board (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$4199.
Custom configuration options -- some of which were standard on the M6459LL/A configuration -- included an Ultra/Wide SCSI hard drive, an internal DVD-ROM drive, 10/100Base-T Ethernet, superior graphics, and a Firewire card, among others.
