I thought about to post the same topic yesterday.

These Macs accept 1GB of RAM and HDDs up to 128GB.

ZIF CPU upgrades up to 1100 MHZ are available.

The 300mhz model is a bit slower because of the halved cache.

The G3 runs a lot more operating systems than my 6100.

I have still one of these and use it for Mac OS 9.2 even I have a G4

Digital Audio.I got simple blue and white speakers and the original mouse and keyboard together with the computer.

Her is something bad to say:

A problem are the rev-1 boards (a buggy Harddisk controller) and the

facts that the machine accepts only single sided RAM sticks and can't boot

from Firewire,USB or ordinary DVD drives.

The power supply works but has 200 W only,while my G4s has 338 W.

My harddisk works but is slow rotating and only 6GB
