I was just thinking as a purely whimsical thing, wonder if it would be hard to use AMTOR as the communication link and use Real Teletype machines for the keyboard and printer, 5-unit code and all.
What got me to thinking of this was that RCA used to have a service based on their ARQ system, which used a code similar to AMTOR but a full-duplex HF circuit, and they connected to plain Teletype customers at both ends.
