I've been looking at upgrading my Beige G3, and I noticed that people here have been able to swap in G4 processors in their G3's... I'm wondering how they did this? Other than upgrade cards made specifically for the older G3's, I can't seem to find any G4 processors that would fit in the processor socket. So, what swaps work? And are there software hacks needed as well? Thanks for any help you can give.
