Ya it's strange! The elevator across the pedestrian bridge doesn't have CB. You might be on to something with proximity to a medical facility, perhaps it's for people riding the train to the sports medicine facility?

"Just use a cloud service! Running things in-house is so outmoded."

I should've been more clear: there's a UW medical center across the street:

I suppose it's near a medial facility - it's the Link station elevator at Husky Stadium!

It is!

I don't. Looks like it says "Tray", a proto clipboard?

It's an AST 486 pc, with a Genius MDS portrait display. It's running GlobalView - a port of Xerox ViewPoint to run on top of windows 3.1.

lol with no cat it might break their equipment

If the plasticizers can leach out from a cable and "melt" the plastic it should would be nice to find a way to "soak" them back in!

I should have added - this system will be on display at @vcfederation.bsky.social VCF West this weekend!

Xerox definitely "rolled their own" when making their own hardware!

I bet the number is very small!
PS: this system is using the PC Emulation board you found for me. It works great!

It was fun figuring out how to recreate the palm tree 🌴

It's another case of "why didn't they sell this!?!" They track a lot more naturally than a Mouse Systems / Sun mouse IMO.

They are for the Xerox optical mous, which tracks a white / black grid. They're printed on a 600dpi laser printer on normal paper, then glued to cardboard so they don't scoot around the desk.
The Xerox mouse is super interesting- the sensor is in a clear DIP package w/ a 4x4 sensor!

I need to bug maceffects about that bezel...
