No, it was not like a Koala pad or touch pad but more
like a digitizing
pad. The end of the arm looks like it has a magnifying lens on it. The arm
assembly looks a lot like a miniature version of a drafting machine.
The arm has joints at its base and middle, right? And the base of the
arm is at the top center of the pad?
I'd expect this thing to look like two game paddles to an Apple ][,
where the obligatory 150K linear pots are mounted at the joints so to
report their angles. That and software could get you a tolerable
digitizing tablet depending on how tolerant you are and the quality of
the pots.
My vague recollection is one of seeing it advertised in Creative
Computing in the early 1980s, maybe by one of CC's related companies,
but I may very well have my wires crossed.
