Now this sounds promising... I've been toying with the idea of doing something similar with a PCMCIA modem card. Electrically, the Springboard slot and PCMCIA seem almost identical. I'd love to see how you've done this.
Interfacing a CF storage card is actually a bit easier. When you look at the Springboard interface, the most notable omission is the I/O bus portion of the interface. There are workarounds, but CF storage cards (which are fully functional in memory-mapped mode) don't require jumping through those hoops. The other problem is that the Springboard slot doesn't support the odd-byte/even-byte chip select architecture that PCMCIA uses. You can get around that with a little glue logic, but again the CF storage adapter dodges that bullet (16-bit access is fully supported) I realize I'm going way off topic here, so if you want to pick my brain about the interfacing issues, feel free to email me directly ([email protected]).
