  • In February, the public got its first glimpse of the ENIAC, a machine built by John Mauchly and J. Presper Eckert that improved by 1,000 times on the speed of its contemporaries.
    Start of project:1943Completed:1946Programmed:plug board and switchesSpeed:5,000 operations per secondInput/output:cards, lights, switches, plugsFloor space:1,000 square feetProject leaders:John Mauchly and J. Presper Eckert.
  • This is a color image of the ILLIAC IV with three men nearest to the camera, standing and working around the system. There are two other men in the far back of the room. The light is coming from the ceiling. Written on verso side on white label is "ILLIAC IV Boston". Also written on verso side is "#1449". Parallel Processing appeared in the huge ILLIAC IV, the first computer to abandon the classic one-step-at-a-time scheme of John von Neumann. ILLIAC IV had sixty-four processors, each with its own memory, all operating simultaneously on separate parts of one problem. Designed at the University of Illinois and built by Burroughs, the computer took six years to complete at a cost of $40 million. It was the fastest machine then in use, but ahead of its time. Plagued by technical ills and very difficult to program, ILLIAC IV was one of a kind. (From:
  • 1965 - Digital Equipment Corp. introduced the PDP-8, the first commercially successful minicomputer. The PDP-8 sold for $18,000, one-fifth the price of a small IBM 360 mainframe. The speed, small size, and reasonable cost enabled the PDP-8 to go into thousands of manufacturing plants, small businesses, and scientific laboratories. (From:
