Interdata's offices and manufacturing facility in Oceanport, New Jersey (here seen in 2022), consisted of four interconnected buildings that were constructed from the 1960s through 1983.

Interdata, Inc.,was a computer company, founded in 1966 by a formerElectronic Associatesengineer,Daniel Sinnott,and was based inOceanport,New Jersey. The company produced a line of 16- and32-bitminicomputersthat were loosely based on theIBM 360instruction set architecture but at a cheaper price.In 1974, it produced one of the first 32-bit minicomputers,theInterdata 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.

Some real-time applications Interdata computers were used for included: Core Protection Calculator, used in some later Combustion Engineering designed nuclear power plants; lottery systems manufactured by GTech; the NexRad weather radar system. Many companies used them for internal high speed laboratory data capture, such as United Technologies Research Center inEast Hartford,Connecticut wind tunnel, General Electric R&D inSchenectady,New York, and Perkin-Elmer in Connecticut (which later acquired Interdata).

The operating system for the 16-bit computers was called OS/16, and for the 32-bit computers OS/32. The assembly language could generate series independent object code. Later, as withGould,SEL,Modcompand other real time competitors, they offered a 32-bit time sharing system called MTM (Multi Terminal Monitor).

Acquisitions

In 1973, Interdata was purchased byPerkin-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 asConcurrent Computer Corporation.
