It's possible -- I don't have the "tablet" portion of it, just the mouse.
The cable has that odd locking connector that the PERQ-1 uses, so I assumed
it was for a -1.  But I may be mistaken.

At any rate, the POS D.6 code (for the PERQ-1 with associated Z80 code)
supports the device, so I assume it existed in some physical form even if
it never saw use outside of 3RCC :).
