Interdata, Inc., was a computer company, founded in 1966 by a former Electronic Associates engineer, Daniel Sinnott, and was based in Oceanport, New Jersey. 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.{{cite web|title=Interdata Reference Manual 29-004R02 – Computing History|url=http://www.computinghistory.org.uk/det/28934/Interdata-Reference-Manual-29-004R02/|website=www.computinghistory.org.uk|accessdate=27 July 2016}} In 1974, it produced one of the first 32-bit minicomputers,{{cite web|title=About Concurrent – Concurrent|url=https://www.concurrent.com/about/about-concurrent/|website=Concurrent.com|accessdate=27 July 2016}} 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.{{cite web |title=Parallel Processing |url=https://www.encyclopedia.com/science-and-technology/computers-and-electrical-engineering/computers-and-computing/parallel-processing |website=Enclicopedia.com |access-date=17 January 2024}}

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 in East Hartford, Connecticut wind tunnel, General Electric R&D in Schenectady, 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 with Gould, SEL, Modcomp and other real time competitors, they offered a 32-bit time sharing system called MTM (Multi Terminal Monitor).

Acquisitions

In 1973, Interdata was purchased by Perkin-Elmer Corporation,{{cite book|last1=Enterprise|first1=I. D.

Interdata then became the basis for Perkin-Elmer's Data Systems Group.{{cite book|last1=Trew|first1=Arthur|last2=Wilson|first2=Greg|title=Past, Present, Parallel: A Survey of Available Parallel Computer Systems|publisher=Springer Science & Business Media|isbn=9781447118428|url=https://books.google.com/books?id=HZzeBwAAQBAJ&q=concurrent+computer+corporation+history+and+interdata&pg=PA76|accessdate=27 July 2016|language=en|date=2012-12-06}} In 1985, the computing division of Perkin-Elmer was spun off as Concurrent Computer Corporation.{{cite web|title=Concurrent Computer Corporation|url=http://www.new-npac.org/projects/cdroms/cewes-1999-06-vol1/nhse/hpccsurvey/orgs/concurrent/concurrent.html|website=www.new-npac.org|accessdate=27 July 2016|archive-date=31 March 2022|archive-url=https://web.archive.org/web/20220331121428/http://www.new-npac.org/projects/cdroms/cewes-1999-06-vol1/nhse/hpccsurvey/orgs/concurrent/concurrent.html|url-status=dead}}
