PowerMacs are not always G3/G4/G5 processors. The first PowerMacs were 601, then I think 603/603e, then 604. Then they went to G3/G4/G5.
As far as I know, there were no G3 Performas from Apple. There might be upgrades though.
Hope that helps :)
I got a Voodoo3 2000 PCI card for my Mac a while back, and now since MacOS X can't use it, I need to put it in my POS Windows box.
By any chance does anyone still have the PC ROM file so I can re-flash the card?
Or a link to a site that has it would be wonderful too!
