I am thinking of upgrading my G3's video card. It has the original Rage 128 in it right now. It is in the PCI 66 slot. My question is about the Rage 128 card- does it work in both 66 and 33 MHz PCI slots?? If I replace it with a new Radeon, I was wondering if I could put the old Rage 128 into an older Power Mac.
