The number of bits associated with a PCI card is how wide the bus is that the PCI card uses to communicate with the system. It also indicates the length of the PCI slot, ie: 32 and 64 bit PCI slots are physically different. You can plug a 32 bit card into a 64 bit slot, but not the other way around. All Macs up until a later G4 models have 32 bit slots with 64 bit slots being added since then. FWIW, a 29160 card might be a little overkill for the 9600 as I think it will be limited by the speed of the PCI bus. Someone with more in-depth information should be able to answer that question better. -- Mr. PopMan - [EMAIL PROTECTED] - "Does anybody want to play a game of pinball?"
