Anyways, the 52x0 only has a 40Mhz FSB, 1MB video RAM, 16-bit color at only 640x480 (256 at 832x634), and 2 DIMM slots. Ugh.
For speed, try out OS 7.5.5 on it - it's on Apple's FTP. However, JJ says newer versions help it out (whatever he means by that) - it can take up to 9.1, which can be upgraded to from the god-awful 9.0 (check Apple's site for those files too).
EDIT: How much RAM is in there? 7.5.5 can boot up inside 3MB, but 8.6 needs like 24. Be careful.
