Computer History Timeline

  • Hewlett-Packard is Founded

    Hewlett-Packard is Founded
    Both Bill Hewlett and David Packard made their first product, the HP 200A Audio Oscillator, which rapidly becomes a popular piece of test equipment for engineers. This product was farily new, and big companies wanted to use it for sounds effects, etc.
    Reason I chose this: I decided to use this event because it was one of the first major inventions in the beginnning of Computer Technology. Also, Hewlett-Packard is still very popular in today's age, selling computers and offering tech support.
  • The Zuse Z3 Computer

    The Zuse Z3 Computer
    Konrad Zuse, a German engineer, finishes the his invention, the Z3 computer. The Z3 was a computer that uses 2,300 relays. In addition to this, the Z3 used floating point binary arithmetic and had a 22-bit word length. Zuse later supervised a reconstruction of the Z3 in the 1960s which is currently on display at the Deutsches Museum in Munich.
    Why I chose this: I chose to higlight the Zuse Z3 computer because it made a huge advance in how to make computers.
  • Colossus is operational at Bletchley Park

    Colossus is operational at Bletchley Park
    This was designed by British engineer Tommy Flowers to break the complex Lorenz ciphers used by the Nazis during WWII. A total of ten Colossi were delivered to Bletchley, each using 1,500 vacuum tubes and a series of pulleys transported continuous rolls of punched paper tape containing possible solutions to a particular code.
    Why I chose this: Not only did it help computer technology advance, but was a major help during WWII.
  • The ERA 1101

    The ERA 1101
    The Engineering Research Associates of Minneapolis built the first commercially produced computer. It used a drum related storing device, the eventually could stored as many as 4,000 words and retrieved any one of them in as little as five-thousandths of a second.
    Why I chose this- This was used a lot by the U.S Navy and became very useful and important. Also, this event introduced the magnetic drum, which was the earliest magnetic storage device.
  • First Labratory Data Processing

    First Labratory Data Processing
    The LINC (Laboratory Instrumentation Computer) offered the first real time laboratory data processing. It was designed by Wesley Clark at Lincoln Laboratories. Why I chose this- Most Researchers used this in biomedical studies. This was important for scientists as well as researchers, giving them a better look for important factors in a lab experiment.
  • The PDP-8

    The PDP-8
    The Digital Equipment Corp. introduced the PDP-8, which was the first commercially successful minicomputer. It sold for $18,000, one-fifth the price of a small another company's 360 mainframe. Why I chose this- The speed, small size, and reasonable cost made the PDP-8 to go into a lot of manufacturing plants, small businesses, and scientific laboratories. It was a huge step towards computer technology in industries and businesses.
  • The Micrel personal computer

    The Micrel personal computer
    This was the earliest commercial, non-kit, personal computer based on a micro-processor, the Intel 8008. Thi Truong developed the computer and Philippe Kahn developed the software.They created the Micral as a replacement for minicomputers in situations that didn´t require high performance.

    Why I chose this- Not only did the Mircal introduce the idea of personal computers, but it was sold for $1,750, making it never hurt the U.S. market.
  • The TRS-80

    The TRS-80
    The TRS-80, aslo known as the Tandy Radio Shack´s 80, was the first desktop computer that was priced at $599.95. It had a video display, 4 kilobytes of memory, BASIC, cassette storage, and easy-to-understand manuals.

    Why I chose this- The TRS-80 introduced the idea of desktop computers to the world and was a huge success in sells, selling 10,000 units rather than the company´s projected sales of 3,000 units for one year.
  • The Osborne 1

    The Osborne 1
    The Osborne 1 was the first portable computer, invented by Adam Osborne. this Osborne 1 computer weighed about 24 pounds and cost $1,795. The machine featured a 5-inch display, 64 kilobytes of memory, a modem, and two 5 1/4-inch floppy disk drives.
    Why I chose this- The price of made the machine especially attractive, mostly because included software worth about $1,500. This machine led many people in the world to start buying portable computers.
  • The Apple PowerBook G4 1.0 17"

    The Apple PowerBook G4 1.0 17"
    The Apple Powerbook G4 1.0 17" was the first notebook with a 17" display and a fiber optic based "ambient light sensor" that automatically measures ambient light . It also was the first Mac to include a Firewire "800" port. It was made and sold by Apple Computer Inc.
    Why I chose this- This laptop was the first laptop to have major imporvements on ambient light and was a very reasonable price. From this laptop, many more versions were made and it helped start the success of Apple products.
