Any ideas?
Just a wild guess, but if you have an HP 35731A 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).

Thanks, Frank. There were two switches on the card
(actually called "composite video interface") and I
tried all four combinations. With one setting I got
garbage. With the other three, the small multi-screen
look, but still very hard to read. I have a few
security monitors in the garage that I'll look at to
see if they're the right frequency.
