Probably "Hercules Graphics Card" - Hercules made the original
mono graphics card that was cloned a lot and most cards for driving
mono monitors are that variety. It gives you 720 x 4?? dots
with each pixel being on or off. As well as being compatible
with the original IBM PC mono video card (which had only text mode).
It does use a 9-pin connector.

Is it backlit? Fluorescent backlights use relatively high voltage.
