HP 95LX/100LX/200LX and alternate I/O


Do any of these units have provision for using an external keyboard or monitor?


There's no provision for a standard external keyboard nor monitor on any of these models. However I believe that someone made an external keyboard that interfaced to the HP100/200LX via the serial port and some driver software. I've never heard of any external monitor device for these machines -- it's hard to imagine how that could be done without a major motherboard modification.



I did a quick Google search and came up with the following links:

HP Journal Keyboard adapted to HP-200LX:


Newton Keyboard adapted to HP-200LX:


Proposed Keyboard for HP-95LX:


Not sure if any of these are actually still available. You may want to spend some time at www.palmtoppaper.com which has a wealth of info on the HP-95/100/200.

Hope this helps.



For DOS sessions, CON: (console device) redirection to COM1: may be something to explore...
