tablet definitely existed, I have half of one (it's the "mouse"
portion, it basically looks like a Hawley mouse without the ball). The
device is supported in the Z80 code, PERQ microcode and POS software.
Are you thinking of the PERQ 2 version that had a synchronous serial
interface? That
certainly exists (in both landscape and portrait versions)?
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 :).

The PERQ1 one looks odd... I seem to remember
something about analogue
signals on the interface connector.
