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

[Dave Shaffer (Arizona)]

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

[Katie]

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.

Dave,

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

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.

Bill
