Basics Peripheral Component Interconnect (PCI) - 67
Peripheral Component Interconnect
(PCI)
The Peripheral Component Interconnect (PCI) expansion
slots accept 6.88-inch and 12.283-inch PCI cards. Because
the PCI bus is an industry standard, most existing PCI 2.0-
compliant cards (with the addition of a Mac OS-specific
software driver) will work in these computers.
PCI offers significantly higher performance than the NuBus
architecture used in previous Macintosh models. Running at
33 MHz, the PCI bus is up to three times faster than NuBus,
offering overall enhanced system performance, particularly
in the areas of video and networking.
