I'm generally interested in hearing from folks who have hacked a Pippin in any way. Various web sites describe the expansion slot as "PCI compatible" and the photos show something that looks like a PCI slot. Is the "incompatibility" an issue of size tahther than signals? -- the original PCI spec defines a card form factor that would be too tall to fit in a Pippin but the slot "looks right". Any pointers to locating a Pippin SDK or developer documentation are welcome. I always try to do my own homework so I've searched the web pretty methodically for info but I'm open for suggestions to add to my bookmarks.

hmm...

It might be a low-profile pci slot. I was working on a PC once that required low-profile pci cards. I'm sure that they are the same as regular PCI cards but just smaller in bracket width.

Check the dates . . .

. . . PCI connectors are actually MicroChannel form factor parts, that bus technology and connector pre-dated PCI by quite a stretch . . . as did the Pippin by a bit, or so I'd be inclined to guess anyway.

PCI in the Intel world preceeded the "Pippin" by about two years (at the high end), but, yeah, the first PCI Macintosh was introduced at almost the same time, so it's probably unlikely that they'd base it on that.

The truth is that the "PCI-like" slot they describe is almost certainly just some sort of unique PDS slot. Apple *loved* unique PDS slots.

When you think about it, just about any expansion slot that uses a parallel bus can reasonably described as "PCI like".;^> Think marketing, here.
