Jornada 68x/7xx HP 10Pin Cable Assignment - Ext KB Driver for other Use??

Hi Gang,

I have a Jornada external kb which uses the proprietary 10 pin HP cable end for plugging in to the Jornada and associated HP cradle port. It would be great to have an Atari-style joystick for certain game use, so I am wondering what the pinout is for the 10pin plug and perhaps use that knowledge with the external kb driver? But then if the kb controls are done through ICs, then it wouldn't be as simple as wiring certin contacts for joystick type movement that represent arrow keys.

Your thoughts and suggestions?

Thanks

Here is the pinout for serial port: http://www.lowlevel.cz/log/pivot/entry.php?id=41
Hope this can help. With the pinout I made a serial adapter for a standard mouse.
