Although parts are starting to wear. The card edge connectors are starting to make poor contact, and other stuff is just getting old.

But when it works, it works like a charm. I'd put my life on the data it produces. This device was brought to you by the White Engineers and Technicians at the Hewlett-Packard Company.

The device itself is a HP3440A. The display tubes are Burroughs B5991 type NIXIE tubes.

It would be great if you could capture a few seconds of the nixie tubes flickering in action in a short video so the "young ones" here can see how cool they were. I haven't seen them in action in about 40 years.

Sounds right. NIXIE tubes. Thanks, bird!

Yep. Nixies are probably one of the most fascinating and cool display methods that we've ever come up with. Bottles full of gasses and fire and high voltages, all to display a number.
