Well, I seem to remember that the old Bell Dataphones
(e.g. 401E)
didn't have much in the way of active components in them. ?One using
tubes should be very easy to work out.
Not hard. The military AN/FGC-5 is pretty straightforward, except for
Teletype's retarded decision to use a magnetically controlled triode.
The rest is textbook dual-triode and mini-thyratron stuff.
