Katz Media PCI riser front

A custom "X-PCI" (bottom) to conventional PCI (top) riser card from a Pippin Expansion Unit by Katz Media.

A computer bus based on Peripheral Component Interconnect (also known as PCI) was used by Pippin consoles to attach proprietary expansion docks. This customized 120-pin connector was referred to as "X-PCI".[1][2]

A Pippin expansion dock can be attached to the bottom of a console to add peripherals contained within the dock, such as a floppy drive or ethernet port. The dock contains a small riser card to connect to the X-PCI bus.[3][4] The X-PCI connector uses the same 120-pin configuration as the Pippin ROMs.[5]
