It's a 98204B card. I've been looking at the original HP displays but I haven't heard anything good about them. I've seen people mention newer multisync LCD monitors that will work with it.

It powers up and it passes all of its diagnostics according to the LEDs on the motherboard. I can see that it is outputting a picture on the composite video connector, but I don't have any displays that will accept the weird sync frequency that it uses. I also do not have an HIL keyboard to use with the machine.
