I do have the manual sets for these, including the QVAF-512 which does
not appear to be on bitsavers. I also have a pile of floppies that I
need to archive, though I think they are mostly the custom software that
U of Rochester used for their laser system.

it'd be a good candidate for anything that requires rapid full-screen
updates, though -- in particular there's no facility for blitting a
graphics region from the -11 to the graphics memory (everything is
drawn on a pixel-by-pixel basis through a set of registers). Were
there any PDP-11 graphics systems that actually had a memory-mapped
framebuffer?
Do you have a manual for the QRGB-GRAPH board. I think
I sent a copy to Al a while back when I could not find it on
bitsavers, but perhaps not.
By the way, Matrox is probably over 40 years old and is located
near Montreal, Quebec. They originally made graphics cards
for systems like the PDP-11, but dropped them long ago when
the demand dried up.
