Vintage ADDS Viewpoint terminal keyboards
Posted: 27 Apr 2022, 23:37
I have a few old ADDS Viewpoint terminal keyboards, which are "Keytronics" [sic] foam and foil linear capacitive keyboards. A search shows one or two posts about these things, but I can't find anything about how the keyboard sends data to the terminal, nor do I see anywhere that someone has successfully built a converter for one.
It occurs to me, though, that they might use a standard protocol or at least the same protocol as some other keyboard that has already been reverse engineered. Does anybody know?
