Honeywell Micro Switch keyboard
Here’s an interesting keyboard with a ghostly white colour scheme. I’m not exactly sure what terminal this goes with but it is a Honeywell keyboard. The original owner modified it to work with a more recent computer.
Internally, it is a Micro Switch keyboard mechanism with hall-effect key switches.
Here are some pics:

I have a Synertek KTM-3 “Tubeless Terminal” which uses this same case, although the keyboard is smaller and made by Stackpole I believe. Honeywell bought Synertek in 1979 and the date on the case is 1981. It has 2 6502s running in tandem to drive the 6551 and generate the video display 🙂
