[GreenKeys] Teletypes seen in the old wild...

[D Smith]

One thing to remember when looking at those TTY's. The baudot models had 3
rows of keys on the keyboard,
and the ASCII models have 4. Quite a few of the police stations had the
model 35 ASR. The electronics were
in the stand below and is what usually we were working on when we were
called to trouble shoot a problem.

When I went down state Illinois, I had about 3 IL State Police Radio
stations that had them, they were always
out in the boonies away from town. I think the Sheriffs had them as well.
They were later replaced by a small
computer looking terminal device called INCOTERM. It was actually a small
computer with magnetic core
memory. It required the operator to type in about 65 characters without
mistakes to boot across a network
from Springfield, IL State Police HQ. I never did see the local police pick
those computers up to replace the
model 35 ASR.  Hams were only allowed BAUDOT at the time, I did have an
'excess'  Model 33 teletype
hooked up for RTTY back then, but I used a home brew 8080 computer with a
translator program I wrote
to use BAUDOT on the air. (That's a nother whole story)
