Apple Power Macintosh G3 450 (Blue & White) Specs (M7553LL/A)
Power Macintosh G3 Main | Ports | Support Links | Q&A | Forums
The Apple Power Macintosh G3/450 (Blue & White), based on the Yosemite architecture, features a 450 MHz PowerPC 750 (G3) processor with 1 MB of backside cache, 128 MB of RAM, a 9 GB Ultra2 SCSI, a 32X CD-ROM drive, and an ATI Rage 128 GL graphics card with 16 MB of SDRAM. Custom configurations also were available.
The Power Macintosh G3 (Blue & White) series unveils a dramatically different translucent "blue and white" enclosure with a "fold down door" on the side that makes the system extremely easy to upgrade. It also introduced Firewire -- a then new high speed peripheral connection standard -- and was the first "pro" system to include USB (along with an ADB port for "legacy" use). It dropped traditional Mac serial ports and onboard SCSI.
Compared to earlier Power Macintosh G3 models, the Power Macintosh G3 (Blue & White) line -- in addition to the even easier-to-upgrade case -- uses generally faster processors, a faster motherboard design with a faster system bus (100 MHz compared to 66 MHz), faster RAM (PC100 compared to PC66), and a faster hard drive standard (Ultra ATA/33 compared to IDE/ATA-2).
