tried the card in both a 9000/200 and 9000/220 with the
same result. Any ideas?
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).

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.

Frank, you were right! I recently picked up a 35731A with a batch of HP
stuff, plugged it into the 98204A, and the video's perfect. Now that I
can see the output, I was also able to confirm that, as expected, an HP
Integral keyboard works with the series 200 HIL card.
Now, if only I could find an OS. HPL or HP BASIC would be nice.

Never mind. Just hooked up a 9134 drive that was with the HP stuff I
got and found that it has HP Basic 2.0 and Pascal on it. Yay!
