Doug is correct. That other TTY is a model 35. They connected those to the SOS down in

Springfield, IL and they processed it further to NCIC in Washington DC.

I'm not sure what the 28 was used for at the time. He is in their radio dispatch room. The squad car back then would radio in a license plate number, the dispatch would type it into the 35 and a querry would come back usually within a minute.

I worked on those between 1971 and 1978 for Western Union. My first year was in Aurora, IL, then I moved on to Bloomington, IL. I did get a call outside my area one time in Elgin, IL where the dispatch said "The keyboard is shot" "bring another" - uh? Those 35 keyboards don't go out ever. Well to my surprise the deputy on dispatch duty at 1am was dry firing, being bored, and sure enough, he shot the damn keyboard. It had a huge hole in it! LOL

> ... He's posing in the dispatch area where a M28 KSR can be seen,

The other machine is a model 35.  Inside the case, the mechanism has a type box like a model 28, but it's 110 baud 8-bit ASCII.  The space that looks like it might house a Model-33 call control unit indeed holds the CCU.  I used to use one of those back in 1969-70.  It's gigantic compared to a Model 33, but somewhat more flexible and designed for heavy service.  (Mostly, my TTY experience is with 33s.)
