Glenn Glen Console in System Test

ADM delivered the first film production console to Glenn Glen Hollywood in 1981. This was the industries first digitally controlled analog console. Like all ADM designs, all audio switching was completed by sealed/wiping relays. The only silicon in the path was in the gain stages. Each of the 65 input strips contained a 6502 microprocessor. Groups of these input strips communicated with a submaster 6809 microprocessor which then communicated with another 6809 microprocessor. This early automation system would save its states on a serially connected CP/M computer system.
