ADM11 terminal keyboard - Low profile Stackpole grid

snuci · 07 Apr 2016, 20:05

This is an keyboard the was used on a Lear Siegler ADM-11 terminal. It has a couple of things that are interesting in that it has the classic looking Stackpole grid switch with the waffle grid but it is low profile and not as tall as I am used to seeing. The other interesting part is the word "Oak" on the PCB. Is this related to Oak switches in some way? Were Stackpole and Oak related?

Here are some pics:

Another interesting one.

Not that I am aware of, but how would I know.
