I went ahead and downloaded the XLR8 firmware block remover. I assume it also works for non-XLR8 G4's.

The G3/500 is a Buffalo (Melco) HG3-G3500 with 1mb cache running at 250mhz. Anybody know how much cache was on the early Apple G4s?

I'm assuming (hoping) that the G4 will overclock to 400mhz, so that I can use the existing jumper block unchanged.

P.S. Do I recall reading that Apple's own G4's will not run with a 66mhz bus? I also have a beige G3 which I could upgrade the leftover processor with.
