    Began work on the Difference Engine
    1821 began work on the Difference Engine, intended to compile and print mathematical tables
  • discussed the principles of a calculating engine

    discussed the principles of a calculating engine
    1822 he first discussed the principles of a calculating engine in a letter to Sir Humphrey Davy
  • HP 200A

    HP 200A
    David Packard and Bill Hewlett found Hewlett-Packard in a Palo Alto, California garage. Their first product was the HP 200A Audio Oscillator, which rapidly becomes a popular piece of test equipment for engineers.

    Maurice Wilkes assembled the EDSAC, the first practical stored-program computer, at Cambridge University. His ideas grew out of the Moore School lectures he had attended three years earlier.
  • 7030

    IBM´s 7000 series mainframes were the company´s first transistorized computers. At the top of the line of computers — all of which emerged significantly faster and more dependable than vacuum tube machines — sat the 7030, also known as the "Stretch." Nine of the computers, which featured a 64-bit word and other innovations, were sold to national laboratories and other scientific users. L. R. Johnson first used the term "architecture" in describing the Stretch.
  • Victor Scheinman´s Stanford Arm

    Victor Scheinman´s Stanford Arm
    Victor Scheinman´s Stanford Arm made a breakthrough as the first successful electrically powered, computer-controlled robot arm. By 1974, the Stanford Arm could assemble a Ford Model T water pump, guiding itself with optical and contact sensors. The Stanford Arm led directly to commercial production. Scheinman went on to design the PUMA series of industrial robots for Unimation, robots used for automobile assembly and other industrial tasks.
  • VLSI systems

    VLSI systems
    California Institute of Technology professor Carver Mead and Xerox Corp. computer scientist Lynn Conway wrote a manual of chip design, "Introduction to VLSI Systems." Demystifying the planning of very large scale integrated (VLSI) systems, the text expanded the ranks of engineers capable of creating such chips. The authors had observed that computer architects seldom participated in the specification of the standard integrated circuits with which they worked. The authors intended "Introduction t
  • 25-MHz

    Motorola announced the 68040 microprocessor, with about 1.2 million transistors. Due to technical difficulties, it didn´t ship until 1991, although promised in January 1990. A 32-bit, 25-MHz microprocessor, the 68040 integrated a floating-point unit and included instruction and data caches. Apple used the third generation of 68000 chips in Macintosh Quadra computers.
  • Iomega Zip Disk

    Iomega Zip Disk
    The Iomega Zip Disk is released. The initial Zip system allowed 100MB to be stored on a cartridge roughly the size of a 3 ½ inch floppy disk. Later versions increased the capacity of a single disk from 100Mbytes to 2GB.
