The History of Computers

  • The Atanasoff-Berry computer.

    The Atanasoff-Berry computer.
    After successfully demonstrating a proof-of-concept prototype in 1939, Atanasoff received funds to build the full-scale machine. Built at Iowa State College (now University), the ABC was designed and built by Professor John Vincent Atanasoff and graduate student Cliff Berry between 1939 and 1942.
  • The complex number calculator.

    The complex number calculator.
    In 1939, Bell Telephone Labratories completed a calculator designed by researcher George Stibitz. Stibitz stunned the group by preforming calculations remotely on the CNC using a Teletype connected via special telephone lines.
  • Bombe computer.

    The British Bombe computer was designed by a computer pioneer named Alan Turing and others. They dramatically improved the intellegence gathering and processing capabilities of Allied forces.
  • The Relay Interpolator.

    The Relay Interpolator.
    The U.S. Army asked Bell Labs to design a machine. Bell Labs mathematician George Stibitz recommended using a relay-based calculator for the project. The Relay Interpolator used 440 relays and since it was programmable by paper tape, it was used for other applications following the war.
  • The Z3 computer.

    The Z3 computer.
    Konrad Zusen was a German engineer. He built the Z3 computer which was later destroyed in a bombing raid of Berlin in late 1943.
  • Harvard Mark-1

    Harvard Mark-1
    The computer was conceived by Harvard professor Howard Aiken, and designed and built by IBM. The machine had a fifty-foot long camshaft. The Mark-1 was used to produce mathematical tables
  • The ENIAC

    The ENIAC
    The ENIAC was a machine built by John Mauchly and J. Presper Eckert. The speed was 5,000 operations per second.
  • Era 1101

    The first commercial produced computer, held 1 million bits on its magnetic drum, the earliest magnetic storage devices. It eventually stored 4,000 words and retrieved them in as little as five-thousand of a second.
  • Project Whirlwind.

    During World War II, the U.S. Navy approached the Massachusetts Institute of Technology about building a flight simulator to train bomber crews. The team first built a large analog computer, but found it inaccurate and inflexible.
  • IBM 650 magnetic drum calculator.

    This established itself as the first mass-produced computer. The company sold 450 of these computers in one year, spinning at 12,500 rpm. It had much faster access to stored materials then drum memory machines.
  • The "stretch"

    This computer was faster and more dependable then vacuum tube machines. Nine computers were sold to the national laboratories and other scientific users. L. R. Johnson designed the 7030 or also known as the "stretch."
  • Apollo Guidance com.

    This computer made its debut by orbiting the earth on Apollo 7. Astronauts communicated with the computer by punching two-digit codes and the appropriate syntactic category into the display and keyboard unit.
  • Virtual projector keyboard

    This projector will allow a computer keyboard to pop out, so you could just type on the table. It will also, help prevent broken keyboards.
  • I-phone wrist watch

    A new device will come out that you would beable to wear! You can wear it on your wrist and it is very flexible. And it has an attached I-phone.
  • Futuristic Worktable and computer

    This new device has a built in coffee table and a work station. It includes a computer and tables that are foldable
