Basics Peripheral Component Interconnect (PCI) - 29
Peripheral Component Interconnect
(PCI)
The 5400 and 5500 series offer a Peripheral Component
Interconnect (PCI) expansion bus. 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).
