Don't know if this is a "great find", but it was cheap enough that I thought I'd let you know about it in case any of you were actually interested in such things (and
not in case some of you had so little to do that you'd go out of your way to criticize someone for taking 10 minutes of their own life to share what they thought
might be of value to someone <--
Note the elaborate, but possibly still futile, appeal to higher brain functions).
Fanuc Control Box Keyboard, A20B-0007-0445/03, USED, WARRANTY$39 shipped

According to other threads here about Fanuc boards, these could be semi-mechanical "hybrid" switches. Or maybe they're just rubber domes; you've got me. It's just something you don't see every day, unless maybe you work in a metal fabrication shop.
Funny how it has only a partial alphabet. And it looks like it still has oil on it from the shop floor—bonus!
