Well, I may be wrong, but the most popular "terminal" was made by the
TeleType corporation (Logo: Letters "TT" with a square wave background)
and called an ASR33. "ASR" indeed stands for "Automatic Send/Receive".
The variants include "KSR" which is "Keyboard Send/Receive"; which had
no paper tape reader/ punch; and receive-only, tape senders,
33 is the model number and this machine could operate at the high
speed of 110 Baud as well as 45.45(!) or 50 Baud. The later ASR/KSR43
was a dot-matrix teletype which could do at least 300 Baud and you could
co-exist in the same room for extended periods without earmuffs!

The ASR33 was ASCII code, but had a limited type-drum now I come to
think of it. It printed all upper case, but you could type in mixed
case - you just couldn't see it as such!
Hey! *Who* remembers the IBM "golfball" machines? These had the full
character set and - you could change font in 20 seconds or so.

That's about the size of it.

Sad to say, when eventually offered one (right price), I had to say
"no" as I hadn't the storage space. Second thoughts - itt was a KSR and
I wanted an ASR. Later however I did pick up a DECwriter (plus a second
for spares without the case!)
