The urgency in this is I suspect that like 80's

gear will all be tossed out as it is replaced by equipment supporting IP
and now is the time to be trying to find it.
I'm interested in preserving the history of stuff related to
terminals, so I guess that includes all the serial line stuff that
isn't IP based: RS-232, RS-432, SDLC, HDLC, etc.
In particular, I've been trying to figure out the synchronous
communications schemes that were used in the airline industry in order
to get some airline reservation terminals in my collection talking.
A lot of that stuff was "proprietary" but I suspect that it was just
some variant (possibly minor enough so as not to be distinguishable on
operating equipment) of an IBM synchronous serial communication
scheme.
