We can certainly investigate using currently available PDA's. It would seem to me that the easiest (and cheapest) route to start with is to setup the Palm emulator and UCLinux. Actually, this might not be a bad route anyway. If the platform will work, one can order a a simm module that carries all that is needed. The distribution is available at www.uclinux.org. They also offer a simm module with a working computer on it that could be the basis for a customized PDA. I will track down the Palm emulator. It is available free. I will post the URL for the emulator after finding it. If someone needs these on CD let me know. I can burn them and mail them for a few bucks to cover my costs.
