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?
The online specs say all "Yikes!" G4s had 1Mb, same as your G3 module. Just now for the heck of it I dragged out my B&W and fired it up to look at System Profiler. (Dang, being turned off for three years can make a system cranky. So much for the PRAM battery...) System Profiler agrees, showing "L2 Cache (per CPU)" as 1MB.
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.
I'm pretty sure that's bunk. When I was given my G4 module I got a pair of them, a 400Mhz and a 350Mhz, and I passed the 350Mhz on to a Beige G3 owner who I'm pretty sure got it running fine at 366Mhz. (Haven't seen them in years either...) As I recall the thing you had to watch out for with Beige G3s is that some of them shipped with a voltage regulator module that's likely to self-destruct with a G4 module. Google for "Royal VRM G3" for more info.
