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.
