The '''HP Visualize j5600 UNIX Workstation''' uses a processor I had not heard of before receiving it (PA-8600).

idk if you've ever used any HP-UX gear before but there are a few quirks while using it:

1. There's a safety interlock that prevents the machine from powering up if the side panel is removed (probably to keep it from overheating or to keep you from shocking yourself on the large bus bars). One of the thumbscrews on the rear basically just screws into the PSU. If you need to bypass the interlock for some reason just thread the screw back in.

2. HP-UX is weird about HID peripherals. The machine uses USB connectors but due to being rather old it can behave somewhat strangely. I would recommend trying to use the most basic USB keyboard and mouse you can find.
If it gets confused for some reason (or no peripherals plugged in) the video will still come up and it will eventually start the desktop but the boot log will be redirected to the serial console. For example if I plug in my G502 this will happen because I think it also detects it as a second keyboard or something.

3. The video connector on the GPUs is an "EVC" connector which was this weird HP thing where I think it was supposed to bundle like video+power+peripherals into a single cable. I'm including an EVC to VGA adapter with it.

4. IIRC the SCSI terminators definitely need to be plugged into the external SCSI ports. I don't think it has any type of old auto-termination thing. I'm including those also.
