Does anyone have a comprehensive list of graphics
products (UNIBUS or
Q-BUS) for the PDP-11 family of minicomputers?
Please don't list terminals with graphics capability, that's not what
I'm after.
I'm not aware of such a list, I believe there are only about 3-6
"video cards". I've a 3rd party card that was used in a Cameca
Microprobe (Electron Microscope). The DEC cards were/are popular in
spectrum analyzers, and a lot of those are still in service in labs.

12 bit color, but we used the green-channel-only as a 16-grey-scale
monitor for displaying ultrasonic scan data (4-bit samples). We used
it with RT-11 and custom-written software. I know nothing about what
driver support there ever was for it, but I do recall that it wasn't
that hard to talk to.

Pictures? Architecture info (some sort of block diagram maybe)?
