Ship, Wolf and anyone else with a long history in theater lighting: who other than Century were building boards in the 50's and 60's. I just saw an old patch bay style system in a dis-used high school in NJ. Sorry I was in total awe and didn't write down any info. It probably predated the (non digital) one I worked on in a school built in 1966/67 which also had rheostat dimmers and a manual patch bay. As best as I can describe it, the patch cords (40) were in a horizontal field, the dimmer circuit jacks, 5 per dimmer, were vertically arranged above, beneath the patch cord field were the breakers for each patchable circuit as well as those for the house lights. The actual control system was all level style rheostats, no possible provision for a remote lighting board. It seemed like the power was off to the entire control system, but four circuits still control scoops hung in the proscenium. In the past someone had removed control of the house lights. Any guesses?
