I think the overlay was custom Apple (it had the funcion menu across the
top), but the tablet was actually a Sumagraphics unit with an Apple
interface card (the pen and the tablet driver PCB are Sumagraphics).
Maybe a standard Sumagraphics overlay could be used (write in the menu
functions by hand or something).

It's a fun toy. I got one surplus before I had an Apple ][, so I made an
interface to connect it to my CoCo. The digital side wasn't too bad (a
CoCo protortyping card covered in TTL counters, etc). But I also had to
make a box with a PSU, drivers fro the tablet trigger lines, and the
sense amplifier for the pen in it. Getting that working, without the
amplifier picking up noise, was an entertainment.
