I need faster text entry, unwilling to spend $200 for a foldable keyboard, unwilling to buy expensive happy hacking craddle. AfAIK the palm seril port is straight rs32, question, is it feasible to make an adapter to use a normal AT or ps/2 keybord on a palm? > > Thanks in advance > Brandon The Palm serial port is a quasi-RS232 port, meaning thay cheat by using lower voltages, but most serial ports will accept it. PC keyboards use a synchronous serial scheme instead so a small microcontroller is needed to at least do the translation to asynchronous rs-232. You can also use to uC to do the translation for the keyboard scan codes into plain ASCII serial data, but be warned, I have yet to find a logic behind the screamingly ugly scan code scheme. :) You could also do it onboard the PC. www.newmicros.com sell little embedded Forth 68HC11 chips that could do the job quite nicely. www.landware.com also seels a cheaper and much more rugged, albeit smaller, non-folding keyboard (GoType). I just bought one and so far it's ok.
