ok, that's useful, thanks. I have a serial cable that came with the machine so
I hooked it up to a DOS box and just used a terminal emulator to check I was
getting data from it. It looks healthy as far as I can tell, although given the
amount of raw data coming back the protocol looks quite complex.

Interesting. I'll have to take it apart now and see what (if anything) it says
in the ROMs that are in there :-)
I found some vague reference to Numonics tablets working under Linux with a
Summagraphics driver if the ID string check is removed, but unfortunately it
doesn't actually say *which* Numonics tablets that applies to. I'll have to
give it a go sometime.

I found a driver disk for Apple systems, but my Mac skills aren't sufficient to
pull apart an Apple driver and engineer an equivalent one on a PC! (which is
what I'd like to use this on)

cheers

Jules
