My friend Evan and I went to the Connections Museum up in Seattle this past weekend to visit for the first time. We were both flabbergasted at what we saw once we had completed the tour, that being both a console unit and a reciever for the AT&T Bell and Lights system that came from the seattle area. Better yet, they were both wired into the No. 1 crossbar switch that the museum has, and were fully operational! I couldn't resist taking a few videos of course, and Evan will have an even better one coming out soon. We soon will hopefully be getting even more info about this system. I cannot understate my excitement.
Enjoy. https://www.youtube.com/watch?v=-lPh5N2WmqM
