[GreenKeys] Early teletype round keyboard.

[Richard Knoppow]

     I never saw one-way call boxes for police in L.A. but we had a 
system of fire call boxes until the mid-1960s.  The police boxes had 
regular common battery telephones in them, a system referred to as the 
"Gamewell" after its manufacturer.  Gamewell probably also made the fire 
alarm boxes. The fire alarm boxes were discontinued and removed after it 
became very common for street people to walk down a street and pull 
every one they came to. It was a simple telegraph system with a code 
wheel in the box which sent the number of the box as spaced pulses. 
These rang bells in the fire houses and also operated a tape register. 
I don't know how long the police call boxes remained in use but they 
were actively used when I worked for the city in the early to mid 1960s. 
The cops were encouraged to use them instead of the radio for running 
suspects, etc, to keep the radio channels clear.
