CDC 3000 - Partial List of Users

Partial List of Users

Oregon State University offered a CDC 3300 for use from the mid-to-late 1960s up until about 1980. It used a home grown operating system known as OS3 (for Oregon State Open Shop Operating System).

The U.S. Internal Revenue Service used CDC 3000 series computers for many years.

A number of CDC 3000s were installed in France, either in academic computing centers, in software companies or in the aeronautics, nuclear and oil industries.

Communist-ruled Hungary obtained a CDC 3300 machine between 1969 and 1971. It was administered by the National Academy of Sciences throughout the 1970s, mainly for running scientific computations.

International Timesharing Corporation sold timesharing services using a CDC 3600.

California State University at Northridge had a dual 3170 that provided timesharing service to the California State University and College system. Many of the other campuses also had CDC 3150 machines for local batch operation.

The US Force used numerous CDC 3800 series systems in the AFSCF Air Force Satellite Control Facility located at what is now Onizuka Air Force Station in Sunnyvale CA. As part of the Air Force Satellite Control Network they were used to do orbital planning and maintenance calculations for DOD satellites until they were phased out and replaced by IBM mainframes in the mid 1980s. These systems used the JOVIAL programming language to provide the accuracy necessary for these calculations.

Other CDC 3300 systems installed in former Eastern Bloc Countries (list not complete):

  • Computing Research Centre, Bratislava
  • Central Statistical Office, Prague.
  • Romanian Aircraft, Bucharest (3500 System)

There were many CDC 3000 series machines in Australia. CSIRO had a 3600 installed in Canberra in 1964, with satellite 3200 machines in Melbourne, Sydney, and probably Brisbane and Adelaide. The Bureau of Census and Statistics had a 3600,3300, and a 3500 in Canberra. Monash University had a 3200: there is a film of its delivery on YouTube. Defence Signals Directorate had at least one. BHP had two 3300 machines at each of its Newcastle and Port Kembla Data centres. They were replaced by 3500s in 1977, and remained in operation until the mid 1980s.

There was a story that Trevor (E.T.) Robinson told the CDC Headquarters that he could sell at least 15 in Australia if CDC built the lower (cheaper) 3000 series.

Famous quotes containing the words partial and/or list:

    There is no luck in literary reputation. They who make up the final verdict upon every book are not the partial and noisy readers of the hour when it appears; but a court as of angels, a public not to be bribed, not to be entreated, and not to be overawed, decides upon every man’s title to fame. Only those books come down which deserve to last.
    Ralph Waldo Emerson (1803–1882)

    Thirty—the promise of a decade of loneliness, a thinning list of single men to know, a thinning brief-case of enthusiasm, thinning hair.
    F. Scott Fitzgerald (1896–1940)
