Xerox purchased Scientific Data Systems (SDS) in 1969, and continued the Sigma computer line until 1975, when it sold its Xerox Data Systems division to Honeywell Information Systems. This presentation includes some brief history and an ORIGINAL XEROX FILM about the San Antonio Gas and Electric Power System and its large scale Xerox computer system in the 1970's. The Xerox footage is undated, but we calculate it is from about 1973 or 1974.Show more
