Re: Teletypes in Police Stations
Our Township PD had a Model 28ASR in service to be able to communicate =20
with the State Police
Headquarters in Lansing Michigan, and to the Secretary of State of =20
Michigan to be able to=20
'run auto plates' to check for stolen vehicles, outstanding tickets, =20
warrants, etc. I was in
the station one day, delivering some fruit for our Band Boosters, and =20
struck up a conversation
with the guy on duty. At that time, they had mostly officers as =20
dispatchers. He was a friendly
sort and we chatted for a while.
He was surprised when I told him that I had a Teletype machine at home!=20
And, that I used it!
I noted that the machine there would come to life from time to time, but=
=20
not print anything.=20
Then I remembered 'Print Suppression', and Selective calling, etc. This=20
machine was on one large
'data loop' including Police stations all over our county, but not =20
necessarily all of them. Mostly
the larger communities.
I asked him if they would have any interest in knowing what the machine=20
was suppressing? In many
instances, a call would go to one community asking for something, and =20
if/when the requester got a
'negative', the query would go to another community, etc. I tried to =20
describe the HAL RVD loop to
Video system, and the later, Leland Associates device which did the same=
=20
thing with different=20
results showing on the screen.=20
The two-way radio shop I moonlighted in had, for some reason, one of the=
=20
Hal RVD units. I told our
boss about the conversation I had with this officer and he had the idea of=
=20
attaching the HAL RVD to
a Teletype in THAT community. He went over and, working with an officer=20
who was in charge of all
of the communications for that department, they got the HAL RVD hooked up=
=20
and connected to a video
monitor. Once the HAL unit was turned on, the screen was showing =20
everything going on when the 'info
loop' had any activity. They saw all sorts of activity directed to and =20
from other communities and
in a few cases, were able to offer assistance in advance of being asked=20
for it! This made a few of
the other community dispatchers a little curious. HOW DID THEY KNOW? Most=
=20
of the dispatchers had
seen their own machines operating without printing, and probably asked a=
=20
Michigan Bell tech what was
going on, etc. The Techs probably knew how to temporarily disable the =20
Print Suppression Solenoid
to make the machine respond to everything. Hopefully, they did not share=
=20
this info or there would
have been a run on Teletype paper!=20
I think that Print Suppression requires the "ZERO BAR" and that not all 28=
=20
printers have this bar. It
is also required for some other operations. Maybe Auto CR/LF and =20
Non-Overline as well.
Anyway, the local Chief was not impressed by the 'eavesdropping' and said=
=20
that their budget would not
allow them to purchase the equipment, anyway. At that time, the HAL RVD=20
was selling for around $495,
and a decent bandwidth video monitor was several hundred dollars more. So,=
=20
that was a short-lived
operation.
Not long after that, Michigan communities made the move to Model 35 =20
machines, and were ultimately
connected to the LEIN System, or "Law Enforcement Information Network". No=
=20
telling what became of those
old Model 28s. I would guess that they belonged to Michigan Bell, and were=
=20
being leased by the various
Police departments. But, I can dream, can't I?
- - - -
Today almost all Police Departments have high speed, high quality =20
computers and high speed lines to a number
of other 'data sources and destinations', and short of having some kind of=
=20
'hacker' on staff, they would
probably not be able to see what is happening in other communities as =20
described above.
