What is the native OS, storage, and boot method for this board? It
sounds like you might be purposing it for your own desires with a close
but not perfect match.

Are you developing your own technology? Or are you re-using standard
technology that's been around for a while?
I think Sun (and others) had X terminals that had smart card slots in
them. This sounds functionally quite similar, just a few substitutions.

That in and of itself does not make what you're doing bad or a waste of
IMHO if you're having fun (other than injuries), learning, reducing
ewaste by reusing things you have, well that all sounds good to me.

Wow. Based on the conversion that I just did, those weren't anywhere

Sounds like salvage parts to play with to me.

/Which/ Linux mailing list. There are *many*.

I was sort of asking because part of me would like to build something
that looks like a DEC vt420 with a look alike (but physically smaller)
case with an LCD (?) display. I've thought about running a Pi and
running XTerm. But that's a pipe dream project for some other time.
