Apple Power Mac G4 The Apple Power Macintosh G4/1.25 (Mirrored Drive Doors 2003) features a single 1.25 GHz PowerPC 7455 (G4) processor with the AltiVec "Velocity Engine" vector processing unit, 256k "on chip" level 2 cache, and 1 MB of DDR SRAM level 3 backside cache. It shipped configured with 256 MB of RAM, an 80 GB Ultra ATA/100 hard drive, a 12X DVD-ROM/CD-RW "Combo" drive, and a 4X AGP ATI Radeon 9000 Pro graphics card with 64 MB of DDR SDRAM. AirPort (802.11b) was available by custom configuration.

The Power Macintosh G4/1.25 (MDD 2003) is a re-released version of the Power Macintosh G4/1.25 DP (MDD) (M8573LL/A) -- due to demand from users who still needed to boot MacOS 9 -- but configured, by default, with a single processor, less RAM, a smaller hard drive, and a DVD-ROM/CD-RW "Combo" drive instead of a DVD-R/CD-RW "SuperDrive". It also sold for a much lower price, US$1299 instead of US$3299.

It was released on June 23, 2003 along with the original Power Macintosh G5 models and discontinued on June 9, 2004 when the Power Macintosh G5 (June 2004) series was introduced.

Please note that this model also could be custom configured with dual 1.25 GHz PowerPC 7455 (G4) processors.

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.
