Can anyone remember what mechanical switch was used to "select stations"?

Before the 83B system there was the 81D1 is I recall correctly.

Most trucking companies used the 83B systems until solid state hardware emerged.

If you think of the 83B system as the mechanical version of the early IP nets it helps to track the end of mechanical systems .Both had their own set of challenges.

ps/

When I was sent to NY Tel in 1970 I was shocked when I noted the use of 19ASR's in their offices when we had long abandoned them in Illinois.

 

Just as Ben points our, the late 60's, early 70's were a
real transition period for Teletype systems. On my first week on
the job with New York Telephone on Long Island, (February,
1970) I was recruited, as the "new kid" to help install
a complete Model 28-based cross-office tape system. It had
several RT sets in cabinets, Model 28 sequence selectors and
lots of other neat stuff. Later on I learned that it was
an 83B3 system, talking to 28ASR's at field locations. The
system was so maintenance-intensive that we had a guy
assigned there full time.

Believe it or not, this system was being
installed at the Avis Rent-A-Car world headquarters.

Sad to say, this system didn't even last for one year and it got
surplanted by the beginnings of the Avis "Wizard" computerized
system. [the equipment was pulled out so fast, I never glot a chance
to scavage anything!]

Ma Bell continued to use torn-tape, Model 15/19-based
systems, internally until the late 70's.
