As Rik mentioned, I/O is practically non-existent on Palm devices. Why
not design your own hardware on a Springboard module and use a Visor,
or on a CF module and use a TRGpro? I've not surveyed the market;
perhaps there are general purpose I/O modules already available in
these form factors.
Also, I'm pretty sure there are much better hardware choices for this
type of application. Find a copy of Embedded Systems Programming
magazine and look at the ads in the back. You'll find some inexpensive
and I/O-rich single board controllers for sale. Heck, with a 68332 chip
and some I/O driver/buffer ICs you would probably have all the hardware
you need.
