IBM mainframes run operating systems supplied by IBM and by third parties. The operating systems on early IBM mainframes have seldom been very innovative, except for TSS/360 and the virtual machine systems beginning with CP-67. But the company's well-known reputation for preferring proven technology has generally given potential users the ...
IBM operating systems have paralleled hardware development. On early systems, operating systems represented a relatively modest level of investment, and were essentially viewed as an adjunct to the hardware. By the time of the System/360, however, operating systems had assumed a much larger role, in terms of cost, complexity, importance, and risk.
An IBM System/360 in use at the University of Michigan c. 1969 IBM guidance computer hardware for the Saturn V Instrument Unit. On April 7, 1964, IBM launched the first computer system family, the IBM System/360. It spanned the complete range of commercial and scientific applications from large to small, allowing companies for the first time to ...
Across its storied 100-year history, IBM (IBM) has been a textbook example of American innovation and technological superiority. While the young whippersnappers may grab all the accolades ...
In a White House ceremony in 1985, Bob Evans and his colleagues, Fred Brooks (responsible for System/360 architecture and design) and Erich Bloch (responsible for System/360 technology) received the National Medal of Technology “for their contributions to […] the IBM System/360, a computer system and technologies which revolutionized the data processing industry.” [6]
OS/360, officially known as IBM System/360 Operating System, [1] [2] is a discontinued batch processing operating system developed by IBM for their then-new System/360 mainframe computer, announced in 1964; it was influenced by the earlier IBSYS/IBJOB and Input/Output Control System (IOCS) packages for the IBM 7090/7094 [citation needed] and even more so by the PR155 Operating System for the ...
Gary Arlen Kildall (/ ˈ k ɪ l d ˌ ɔː l /; May 19, 1942 – July 11, 1994) was an American computer scientist and microcomputer entrepreneur. During the 1970s, Kildall created the CP/M operating system among other operating systems and programming tools, [5] and subsequently founded Digital Research, Inc. to market and sell his software products.
IBM enhanced one of GM-NAA I/O's successors, the SHARE Operating System, and provided it to customers under the name IBSYS. [1] [2] As software became more complex and important, the cost of supporting it on so many different designs became burdensome, and this was one of the factors which led IBM to develop System/360 and its operating systems ...
