A few  years back I was given a M15 machine that had apparently been
abandoned by  AP at a radio station and taken home by the station
engineer when he  retired.  Two documents came with it, which I have
attached.  One  is pretty clearly aimed at maintenance people with some
training, but the  other calling for a change to 50 baud gears seems
to be aimed at the  station personnel.  Too bad the letter of transmittal
is not  dated.  In any event when I got the machine it was still geared for
45  baud.  Maybe the speed change never took place in this neck of  the
woods.

The machine in the pictures appears to have the Teletype  Corp. solid state
selector magnet driver replacing the polar  relay.

It's curious that they give increased speed as the reason for  the
change, yet the change from 45 to 50 baud produces only a modest  increase
in speed.  They could have gone to 75 wpm gears for the 15s  and got
more speed out of them.

Something else I've been meaning to  ask about - this machine like a number
of others I have seen had the  "Associated Press" placard on the front of
the cover.  In my youth  when I hung around newspapers and radio stations
watching the Teletype  machinery I don't recall those placards being on
the machines.  My  guess is that they came into use in connection with
television stations  broadcasting pictures of their news rooms and all
the different wire  service Teletypes they had.  Each wire service then
needed to show its  presence among its competitors.

Another curiosity about this machine is  that it was not on a Teletype
Corp. table, but on a homemade table, made  from the kind of steel angle
stock sold at hardware stores, and  plywood.  And there was a sticker on
the table with instructions for  setting a timer clock; so apparently
they had a clock to turn the machine  on and off at certain times of  day.
