It's a Burroughs branded Honeywell Hall Effect keyboard, and has some variants of the Hall Effect switches that I hadn't seen before. Namely, a lockable switch.
Also cool, is the entire keycap cover re-legendables.
The case quality is sorta meh, not bad, but not at the usual standards of Burroughs and Honeywell.
I have 2 of these keyboards, one with the key included. I'm open to trades, and offers. If it takes too long, I'll just donate it to some Deskthority contest.

Maybe by then I'll have a converter ready.

Probably was used for some government facility/contractor or something.


Bet'cha you've never seen triple zeros before


Dunno about the purpose of the dual one way tab keys...

Key for something, it's wired to the PCB inside.



Lolwut, FCC Non-Certified







5A3E is the lockable switch.

Keycap goodness
