Honeywell Information Systems, Inc.

Honeywell entered the computer business when, in 1955, it formed a joint venture with the Raytheon Manufacturing Company to create the Datamatic Corporation. In the early 1960s, Honeywell bought out Raytheon’s interest and also purchased the Computer Control Corporation to further add to its product line. At this point they had machines that competed directly with those of IBM and other major manufacturers.

In 1970, they acquired General Electric’s computer division which gave them access to the timesharing system known as Multics. Multics later set the standard for timesharing systems, particularly in regard to security. In 1986 they merged with the French Compagnie des Machines Bull and Nippon Electric Company (NEC) to form Honeywell-Bull, but by 1991 they had left the computer business entirely.
