Back in 1999 I was still doing the crawling-under-desks thing. I was at a tobacco companies sales office... and they had a wallplate with ports labeled token ring, ethernet, and appletalk (looked rj11, so phonenet?). A year or two later I worked at their central location in Virginia in a warehouse decommisioning old equipement, got to see some FDDI and HIPPI hardware. Never saw it being used though.
And at my previous job, in a quite normal office, there was a wallplate labeled DEC with the weirdest jack I've ever seen. I couldn't visually identify it, and I thought I knew everything. 1.5" inches wide, with a plastic spring-loaded cover that came down from the top. Maybe only two conductors in it, not normal rj-style pins at all. I'd guess something Vax, but I thought those were always ethernet since the early 80s, and anything older still wouldn't likely have survived until 2025.
