iMac G3/500 (Early 2001 – Flower/Blue)

The iMac G3/500 released early in 2001 stands apart from the previous G3 iterations. Not only the processor speed was increased, but also the cache memory and the VRAM. The hard drive and RAM capacity weren’t increased significantly, but the CD drive was now a writing one. So, the iMac G3/500 features a 500 MHz PowerPC 750cx (G3) processor with a 256k on-chip level 2 cache, 64 MB of RAM, a 20.0 GB Ultra ATA hard drive, a slot loading 8X/4X/24X CD-RW drive, ATI Rage 128 Ultra (AGP 2X) graphics with 16 MB of VRAM and Firewire “400” ports not to mention the in-built speakers, a 15-inch CRT display and AirPort support. The iMac G3/500 is available in three colors: Indigo, Flower Power, Blue Dalmatian.
