Quite likely. I know in years past, I worked with a unibus VAX that
had a drum transparency scanner attached. (It was a really nice
scanner, too; if I'd had hardware interface docs and space, I'd've
snagged it on its way out.) This is relevant because the interface to
it consisted of a section of what looked like unibus backplane that had
been completely rewired (or perhaps it started as bare card-edge
connectors and calling it _re_wired is inappropriate :-). There were a
half-dozen or so boards that had to be plugged into this special
section of backplane, each in the right slot.

It wouldn't surprise me a bit if your framebuffer/digitizer was done

Ah, working with the 780 and 750. Those were the days.
