[GreenKeys] Teletype Switchboard photo...

[Phil Schelinski]

Hard to believe that AT&T TTY  operators were still active in the late '60's.
I can't remember the name of the modified Strowger switch that transferred TTY circuits between AT&T 10th flr Dearborn Test and O'Hare field using +/- 130VDC Polar transmission..
The switch was similar to those used for 81D1 circuits.
