Just a wild guess, but if you have an HP 35731A monochrome monitor,
try it with that. That wants composite video but with a horizontal
frequency of 30KHz instead of the more usual 15KHz. HP used that on
several different systems.

There may also be a jumper on the video card to select the
horizontal frequency, but the only thing I ever saw this on was
the HP Multimode Display Adapter for the Vectra (sort of a
combination of the IBM MDA and CGA that was good for confusing
"smart" software).
