obviously, there are other colors than blue possible, but none others

Or else they have a 24 bit pixel depth, which would be very impressive.
Our grinell had more than one buffer, and you could do operations
between them too.
I dare say we can safely assume it's not a
serially connected terminal
(even ignoring that I don't think I've ever seen or heard of a serial
terminal with bitmap graphics with a resolution close to this).
I agree here ;-)
Ours was also attached via a DRW whatever on the bus.
(Sorry, thirty years ago ;-))
Never heard of grinell.
But I have a VSV21 here. 640x480 pixel resolution. Unfortunately only 4
bitplanes. But it's a very fun graphic system for the PDP11 anyway...
And later than 1981, but made by DEC. Oh, and that's for the Q-bus...
Unibus graphic systems are rarer...
I should have them here too. One day ...
