For a VS3100 M76 SPX the video cable is a BC23J. That's the cable I use
with my M76 SPX to connect it to an NEC MultiSync CRT. 15-pin to 3 BNC
connectors.
The SPX graphics controller is switchable between 60 Hz 1024 x 864 and 66
Hz 1280 x 1024.

That webpage has the correct pinouts listed. However, under the heading
"How to connect a Sony Multiscan monitor to a VS3100", it suggests
connecting pin 9 on the VAX (monochrome signal) to pin 6 on the monitor
(red return). The monitor may well have all the returns connected
together so the display may work fine and the incorrect connection may
not be noticed but damage could be done to whatever is driving the
monochrome signal on the VAXstation system board.
