  • Sperry Rand's Third-Generation Computers 1964–1980
    Sperry Rand’s Third-Generation Computers 1964–1980 George T. Gray and Ronald Q. Smith The change from transistors to integrated circuits in the mid-1960s marked the beginning of third-generation computers. A late entrant (1962) in the general-purpose, transistor computer market, Sperry Rand Corporation moved quickly to produce computers using ICs. The Univac 1108’s success (1965) reversed the company’s declining fortunes in the large-scale arena, while the 9000 series upheld its market share in smaller computers. Sperry Rand failed to develop a successful minicomputer and, faced with IBM’s dominant market position by the end of the 1970s, struggled to maintain its position in the computer industry. A latecomer to the general-purpose, transistor would be suitable for all types of processing. computer market, Sperry Rand first shipped its With its top management having accepted the large-scale Univac 1107 and Univac III comput- recommendation, IBM began work on the ers to customers in the second half of 1962, System/360, so named because of the intention more than two years later than such key com- to cover the full range of computing tasks. petitors as IBM and Control Data.

    The Univac 90 / 60 Mainframe Computer Figure 1: Univac 90/60 aka RCA Spectra 70/7 This particular machine seems to have had the Univac signage applied to the CPU but retains the cosmetic features of the Spectra 70. This photo was found on the web at http://www.rwc.uc.edu/koehler/cshist.html Introduction: The first full-scale computer that I had the opportunity to work with was the UNIVAC 90/60 located at Edinboro State College in the late 1970’s and early 1980’s. This was a third-generation mainframe computer whose processor architecture and instruction set was based on the IBM 360. Unlike the “clone” and “plug compatible” systems that were made later by Amdahl and others, the I/O architecture was different enough that IBM operating systems wouldn’t run on the UNIVAC and user programs needed to be re- compiled. Page 1 of 16 The Univac 90 / 60 Mainframe Computer Unfortunately, there is currently very little information on the web about these machines. I have been thus far unable to locate a reasonably clear photograph of ANY 90/60, let alone a photograph of the actual system I was able to use. Even Wikipedia has little to say about the UNIVAC 90/60. The article accessed on 7/21/2007 is reproduced here in its entirety: UNIVAC 90/60 From Wikipedia, the free encyclopedia The Univac 90/60 series computer was a mainframe class computer manufactured by Sperry Corporation as a competitor to the IBM System 360 series of mainframe computers. The 90/60 used the same instruction set as the 360, although the machines themselves were not compatible with each other; programs written for one would have to be recompiled for the other, as at the time they were developed, the concept of an operating system being portable separately from the computer system it ran on was unheard of.
