That is a Laserphysics Reliant PSU and Tube..
Probably a Reliant 150M or 250M.
M= OEM/Multimode
One of the few tubes that ages gracefully, but with a PSU that objects to being shocked with a BD10 Tester. Remove the tube from the unit before testing. (Sorry Brad, you didn't know)

A bit of googling around here might get you a PSU pinout, but probably for a DB9 or DB15 on a daughter board you may or may not have.
I have no way of knowing if the PSU DB connector extension in the pic matches the standard or not. Some need an outside voltage to start, others just want shorted pins, some want both, ie isolated daughterboard. I cant remember what is what, its been, what a Decade, since I last had one.. They came in a variety of PSU input voltages, too.. Its not auto-switching for line voltage. In other words I remember a few variations. I'm thinking posts by "DZ" might have the best information.

If no one chimes in, you'll have to reverse engineer the circuit.
The show content for that laser system was probably on the CD, I'm not sure you'll find much on the hard drive.
Other ports would be the color option.
In the 90s there were a few different systems of that design floating around, made by a long gone OEM in the pacific northwest.

Check for corrosion around the BIOS battery before you fire it up.

Lasernet is still in business. Maybe their engineer remembers, and they either remarketed it, or built their own.
