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)

Doug is correct. That other TTY is a model 35.

Thanks Doug and Danny. I have a vague recollection of the Model 35 but of course the model 33 was ubiquitous when I started messing with microcomputers in the 70s. Although few hobbyists could afford them!

I know that ASCII was just starting to come into widespread use in the late 60s or early 70s when this photo was taken, so it makes sense that it was connected to a more modern system. The village of River Forest was quite wealthy, being the home of Paul Harvey, the founder of the Mars candy company, and numerous mobsters - so they could afford all the newest toys ;-)
