The original Apple iMac - Bondi (Rev. A & B), based on the Columbus architecture, features a 233 MHz PowerPC 750 (G3) processor, 512k backside level 2 cache, 32 MB of RAM, a 4.0 GB EIDE hard drive, and either ATI Rage IIc graphics with 2 MB of VRAM or ATI Rage Pro Turbo graphics with 6 MB of VRAM packed in a "bondi blue and ice" colored, "retro futuristic" all-in-one case design with a 15-inch "crystal clear" CRT display.
Apple promoted the iMac as a revolutionary new Mac for the Internet age, hence the "i" prefix, and it was unique not only for its look, but also for being the first Mac to include USB ports -- a then new standard from the Wintel world with support for up-to 127 devices -- replacing SCSI, ADB, and Mac serial ports. It also was unique as it was the first Mac to lack a floppy drive.
The "revision A" iMac (M6709LL/A) and "revision B" iMac (M6709LL/B) are identical with the exception of graphics systems. The "revision A" model -- introduced May 6, 1998 and shipped August 15, 1998 -- has ATI Rage IIc graphics with 2 MB of VRAM and the "revision B" model -- introduced October 26, 1998 -- has ATI Rage Pro Turbo graphics with 6 MB of VRAM.
