In 1984 estimated sales of desktop computers ($11.6 billion) exceeded mainframe computers ($11.4 billion) for the first time. IBM received the vast majority of mainframe revenue. [21] During the 1980s, minicomputer-based systems grew more sophisticated and were able to displace the lower end of the mainframes. These computers, sometimes called ...
IBM 704 mainframe at NACA in 1957. From 1952 into the late 1960s, IBM manufactured and marketed several large computer models, known as the IBM 700/7000 series.The first-generation 700s were based on vacuum tubes, while the later, second-generation 7000s used transistors.
The IBM System/360 (S/360) is a family of mainframe computer systems announced by IBM on April 7, 1964, [1] and delivered between 1965 and 1978. [2] System/360 was the first family of computers designed to cover both commercial and scientific applications and a complete range of applications from small to large.
IBM 7010 system: console (in front), disc drives and processing modules (left), tape storage, punch card reader and printer (right) The 700/7000 commercial architecture inspired the very successful IBM 1400 series of mid-sized business computers. In turn, IBM later introduced a mainframe version of the IBM 1410 called the IBM 7010. Data format
The IBM 701 was the first computer in the IBM 700/7000 series, which were IBM’s high-end computers until the arrival of the IBM System/360 in 1964. [5] The business-oriented sibling of the 701 was the IBM 702 and a lower-cost general-purpose sibling was the IBM 650, which gained fame as the first mass-produced computer. [4] [6]
The IBM 704 is the model name of a large digital mainframe computer introduced by IBM in 1954. Designed by John Backus and Gene Amdahl, it was the first mass-produced computer with hardware for floating-point arithmetic. [1] [2] The IBM 704 Manual of operation states: [3]
International Business Machines (IBM) used to dominate the computer industry -- especially in the 1960s when mainframe computers were the only game in town. During the 1970s, that dominance gave ...
The IBM System/370 Model 145 was announced September 23, 1970, [1] three months after the 155 and 165 [2] models. It was the fourth member of the IBM System/370 line of computers, [ a ] and was the first IBM computer to use semiconductor memory for its main memory instead of magnetic core memory . [ 4 ]
