Many of these 35 KSR sets were used as terminals to communicate with the #1 ESS WECo electronic switch.
I had one in my museum. By the time the #5 ESS came out the terminal used was the Model 40 KDP.

The Number 101 ESS… the first WECo electronic switch, had a Model 28 KSR
with a modified keyboard and a modified type box.  It was very weird.

All except the #5 were coupled to the switches with a -130Vdc 62.5 milliamp loop.

The Bell System provided the USA with the finest telecommunications network in the world.
I am pleased that I was part of it.  DRH
