  • Complex Number Calculator (CNC)

    This calculator was the first example of remote access computing. My company uses this to allow tech support to fix our computers from Texas.
  • The Z3 Computer

    The Z3 Computer
    Created by: Konrad Zuse
    This computer was a German computer that was destroyed in a bombing of Berlin in 1943. This computer was especially built for aerodynamic computing. The Z3 was an early computer model and helped pave the way to the creation of the computers we know today.
  • The Atanasoff-Berry Computer (ABC)

    The Atanasoff-Berry Computer (ABC)
    Created by: Professor John Vincent Atanasoff and graduate student Clifford Berry
    The ABC is the originator of several different original ideas having to do with the invention of the computer. A fully functioning replica of the ABC can still be found in a computer history museum today. The ABC could possibly have been the first computer ever built.
  • First Colossus Operations at Bletchley Park

    First Colossus Operations at Bletchley Park
    Created by: Tommy Flowers
    This machine was created to break the complicated Lorenz ciphers that the enemy had been using during the second World War. Ten of these machines filled with up to 2500 vacuum tubes, pulleys, and rolls of punched paper tape lined up in a field helped reduce the length of the war. This miracle of engineering did so by reducing the amount of time it took to decode these messages from weeks to hours.
  • Manchester Mark I Williams-Kilburn tube

    Created by: Freddie Williams and Tom Kilburn
    This was the first high-speed, entirely electronic memory. This invention used a cathode ray tube to store bits as dots on a surface or screen. The dots appear and then fade away thus constantly refreshing the information. Information was then read by a metal plate that detects any change. We use electronic memory everyday to save all of our important information.
