Perfect. Thanks, Alan!
I don't happen to have a VR201 here right now
to measure directly (or
I would just do that), but IIRC, there's a threaded mounting insert on
the bottom...
There are four brass inserts in a trapezoidal pattern, each threaded
1/4-20 (National Coarse). The trapezoid is 7.0" center-to-center
for the two nearest the screen, and the rear ones are 5.0" center-to-center.
It is 5.0" between the front (screen) pair and the rear pair. Now, could someone please tell me the pinouts for the
15-pin connector?
I would like to use it to view RS-170 video, if possible.
From the Rainbow pinout...

... I think the VR201 certainly matches the subset of that. I don't
know if the color pins are N.C. on thje VR201 (but I would hope so),
but I have wired up a DA15 cable to tap +12V from an Amiga 2000 and
display mono video from its mono composite output...
