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 PDP8E 12-bit computer was used to control the programming as well as to prepare the music and programming lists.  It used a 2 and 1/2 megabyte disk on a 14 inch platter to store the data.

I recently found these slides that were taken in 1975 of some old friends.
