I have seen the same dial box, as well as the "Button Box" and
possibly the CAD puck with the crosshairs, for HP and, IIRC, Sun
systems.  It's a fair bet they're all based on the same models.

"Somewhere" in my overwhelming stacks of IBM docs, I have some sort of
guide to I/O devices with pics of each.  I don't believe I've ever
seen a protocol description in them, unfortunately.
