Vintage ADDS Viewpoint terminal keyboards

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?

Definitely something non-standard: viewtopic.php?f=7&t=25149&p=477509

That's exactly what I am looking for. Thanks!

I have a couple different models all of which are different from MMcM's. It will be interesting to see if they all speak the same language. I suspect yes.
