[GreenKeys] Crawford Generating Station Teletypes, Chicago...

[Jim Haynes]

And we have to remember that it was long Bell System policy to destroy
old Teletype equipment prior to the mid-1950s.  They didn't want anybody
getting the equipment and using it in competition to the services they
were selling.  It took a lot of work on the part of some hams to convince
the Bell System to sell the old Teletype equipment to hams, and required
setting up a bunch of "Teletype societies" across the country to handle
the equipment.  Hams had to sign a form promising never to use the
machines commercially and to require a form like that from the buyer
if they sold a machine.
