ATT Private Payphone Schematic
« on: September 30, 2017, 04:40:47 PM »
Would anyone happen to have a diagram of how the handset and keypad conncetions?  I also have 2 red wires coming from the coin chassis I have no idea where they go to.

I'm going to try to power this up and see what happens. I have a 24v CT power transformer. the original wall transformer is long gone.
