Well, I feel pretty deep into that rabbit hole, where I’ve even designed a couple of primitive circuit boards and hand-wired a bunch of keyboards. I also mess stains worth vintage stuff a bit.

This particular converter is programmable and meant to be used with a not mechanical 122-key terminal keyboard made by the company that took over IBM’s US keyboard factory, but it’s been hanging out with several DuPont wires shoved into it to connect it to a molex connector to test a different old board.
