I have a G3 AIO for sale. It has a 233MHz (oc to 292M) G3, 128M RAM, 9G IDE HD, second NIC card, ADB KB and mouse. Thoroughly cleaned and everything works. Can demo dual boot OS9 and OSX.
Asking $110.

Pardon my ignorance but what's an AIO?

Power Mac G3/233 AIO

The Apple Power Macintosh G3/233 AIO, based on the ultra-compact Gossamer logic board, features a 233 MHz PowerPC 750 (G3) processor, 32 MB of RAM, a 4.0 GB hard drive, ATI 3D Rage II+ (Rage Pro after May 1, 1998) graphics acceleration, and the standard "Whisper" personality card with audio input/output, in an easily expandable all-in-one case. Custom configurations were also available to North American education customers. Unfortunately, this computer was not offered to the consumer market, or outside North America.
