    The world's first general purpose electronic computer was introduced

    1949:CSIRAC runs first program

    While many early digital computers were based on similar designs, such as the IAS and its copies, others are unique designs, like the CSIRAC. Built in Sydney, Australia by the Council of Scientific and Industrial Research for use in its Radio physics Laboratory in Sydney, CSIRAC was designed by British-born Trevor Pearcey, and used unusual 12-hole paper tape. It was transferred to the Department of Physics at the University of Melbourne in 1955 and remained in service until 1964.
  • 1950's:ERA 1101 introduced

    1950's:ERA 1101 introduced

    One of the first commercially produced computers, the company´s first customer was the US Navy. The 1101, designed by ERA but built by Remington-Rand, was intended for high-speed computing and stored 1 million bits on its magnetic drum, one of the earliest magnetic storage devices and a technology which ERA had done much to perfect in its own laboratories. Many of the 1101’s basic architectural details were used again in later Remington-Rand computers until the 1960s.

    The computers during this time span was the
    Ferranti Mark 1,
    Univac 1,
    Nimrod at the Festival of Britain Nimrod,transistorized computer,IBM 650 magnetic drum calculator, and Model 501 transistorized computer
  • DEC PDP-1 introduced

    DEC PDP-1 introduced

    The typical PDP-1 computer system, which sells for about $120,000, includes a cathode ray tube graphic display, paper tape input/output, needs no air conditioning and requires only one operator; all of which become standards for minicomputers. Its large scope intrigued early hackers at MIT, who wrote the first computerized video game, SpaceWar!, as well as programs to play music. More than 50 PDP-1s were sold.
  • IBM 7030 (“Stretch”) completed

    IBM 7030 (“Stretch”) completed

    IBM´s 7000 series of mainframe computers are the company´s first to use transistors. At the top of the line was the Model 7030, also known as "Stretch." Nine of the computers, which featured dozens of advanced design innovations, were sold, mainly to national laboratories and major scientific users
  • Period: to

    1962 -1963

    The Minuteman I missile guidance computer, Atlas Computer, and Naval Tactical Data System were introduced between 1962 and 1963
  • MIT LINC introduced

    MIT LINC introduced

    The LINC is an early and important example of a ‘personal computer,’ that is, a computer designed for only one user. It was designed by MIT Lincoln Laboratory engineer Wesley Clark. Under the auspices of a National Institutes of Health (NIH) grant, biomedical research faculty from around the United States came to a workshop at MIT to build their own LINCs, and then bring them back to their home institutions where they would be used.
  • CDC 6600 supercomputer introduced

    CDC 6600 supercomputer introduced

    The Control Data Corporation (CDC) 6600 performs up to 3 million instructions per second —three times faster than that of its closest competitor, the IBM 7030 supercomputer. The 6600 retained the distinction of being the fastest computer in the world until surpassed by its successor, the CDC 7600, in 1968. Part of the speed came from the computer´s design, which used 10 small computers, known as peripheral processing units, to offload the workload from the central processor.

    1965-1968

  • Amdahl Corporation introduces the Amdahl 470

    Amdahl Corporation introduces the Amdahl 470

    Gene Amdahl, father of the IBM System/360, starts his own company, Amdahl Corporation, to compete with IBM in mainframe computer systems. The 470V/6 was the company’s first product and ran the same software as IBM System/370 computers but cost less and was smaller and faster.
  • Cray-1 supercomputer introduced

    Cray-1 supercomputer introduced

    The fastest machine of its day, The Cray-1's speed comes partly from its shape, a "C," which reduces the length of wires and thus the time signals need to travel across them. High packaging density of integrated circuits and a novel Freon cooling system also contributed to its speed. Each Cray-1 took a full year to assemble and test and cost about $10 million. Typical applications included US national defense work, including the design and simulation of nuclear weapons, and weather forecasting.
  • Atari introduces its Model 400 and 800 computers

    Atari introduces its Model 400 and 800 computers

    Shortly after delivery of the Atari VCS game console, Atari designs two microcomputers with game capabilities: the Model 400 and Model 800. The 400 served primarily as a game console, while the 800 was more of a home computer. Both faced strong competition from the Apple II, Commodore PET, and TRS-80 computers. Atari's 8-bit computers were influential in the arts, especially in the emerging DemoScene culture of the 1980s and '90s.
  • Commodore introduces the VIC-20

    Commodore introduces the VIC-20

    Commodore releases the VIC-20 home computer as the successor to the Commodore PET personal computer. Intended to be a less expensive alternative to the PET, the VIC-20 was highly successful, becoming the first computer to sell more than a million units. Commodore even used Star Trek television star William Shatner in advertisements.
