From September 1972 until July 1977, I was one of the three engineers producing and maintaining the equipment at KCBS-FM in San Francisco. During that time, the station used the IGM 770 automation system to produce the on-the air programming. A DEC PDP8-E 12-bit computer was used to control the programming as well as to prepare the music and programming lists. It used a 2.5 megabyte, 14″ disk for data storage.
