The company produced a line of 16- and 32-bit minicomputers that were loosely based on the IBM 360 instruction set architecture but at a cheaper price. In 1974, it produced one of the first 32-bit minicomputers, the Interdata 7/32. The company then used the parallel processing approach, which uses more than one computer processor simultaneously to perform work on a problem. This helped in making real-time computing a reality.2

Acquisitions
In 1973, Interdata was purchased by Perkin-Elmer Corporation, a Connecticut-based producer of scientific instruments for $63.6 million. Interdata was already making $19 million in annual sales but this merger made Perkin-Elmer's annual sales rise to over $200 million. Interdata then became the basis for Perkin-Elmer's Data Systems Group. In 1985, the computing division of Perkin-Elmer was spun off as Concurrent Computer Corporation.
