Fred Nelson in Chicago has a beautifully restored switchboard in his family room connected to the house phone network. It's very fun to play "Lilly" with!
I worked my way through high school and college working one of these at the phone company. This is a PBX (private branch exchange board (WE 556A)) much smaller than the phone company toll office board. It works and a lot of fun. Lilly Tomlin's character Ernestine was one of my favorites! That's a genuine Western Electric switchboard chair.
