Documenting the Apple Pippin expansion connector #Apple #Gaming #VintageComputing @abzman2000

Evan’s Techie-Blog is diving into documenting the expansion interface for the Apple Pippin game console (more on Pippin on Wikipedia).

This (Pippin) was supposed to have other accessories, and some actually exist. Floppy we know already, but ethernet, SCSI, zip disc, and even this strange magneto-optical drive. The thing is, after looking at all the boards it seems that they all just use PCI-to-blah adapter chips, like PCI to SCSI for the drives. There was even an adapter to a regular old PCI slot. This is a little harder to trace than a simple floppy adapter board though.

After doing some digging I found this great website mostly preserved on the wayback machine. It has a partial pinout for the XPCI slot as they call it (not to be confused with PCI-X) and it includes all the PCI lanes that I think are needed. After combining that with the floppy adapter I now have a much more complete picture of the Pippin connector pinout.

Read more and find a link to the pinout spreadsheet in the post here.
