My guess is the tty culture on UNIX revolved around
the Model 37. This had
upper and lower case as well as having the concept of NEWLINE as both the shoot
the paper up and move the type element back to the left side. It ceratainly
is ingrained into nroff, all those ESC-8/ESC-9 stuff that nroff puts out are
direct commands to the Model 37.
I suspect that it was just the case that most PDP consoles were Model 33’s.
They were cheaper and pretty ubiquitous. Even when I started with UNIX in
1977, most of our machines had Model 33 consoles even if they had CRTs or
fancier printing terminals (LA36 or Model 37’s).
I don't think that I agree with this. I recall that there was a "public
terminal
room" on maybe the 4th floor of building 2 that was filled with random terminals
of all types hooked to modems. It's where I first came across glass ttys. I know
that many of the UNIX machines had modems; I would borrow a Silent 700 or Execuport
so that I could work from home which annoyed my parents since I would tie up the
phone. So while I don't recall doing so one could dial one up from one of the glass
ttys in the public terminal room.
