  • First programmable computer

    The Z1 computer was created. It was created by german Konrad Zuse.

  • The first stored program computer

    "The early British computer known as the EDSAC is considered to be the first stored program electronic computer. The computer performed its first calculation on May 6, 1949 and was the computer that ran the first graphical computer game." "Electronic Delay Storage Automatic Calculator, EDSAC is an early British computer."

  • The first PC (IBM compatible) computer

    On April 7, 1953 IBM publicly introduced the 701 , its first electric computer and first mass produced computer. Later IBM introduced its first personal computer called the "IBM PC" in 1981. The computer was code named and still sometimes referred to as the "Acorn" and had a 8088 processor, 16 KB of memory, which was expandable to 256 and utilizing MS-DOS .

  • The first computer with ram

    "MIT introduces the Whirlwind machine March 8, 1955 , a revolutionary computer that was the first digital computer with magnetic core RAM and real-time graphics."

  • The first transistor computer

    "The TX-O (Transistorized Experimental computer) and first transistorized computer is demonstrated at the Massachusetts Institute of Technology."

  • The first minicomputer

    "In 1960 Digital Equipment Corporation released its first of many PDP computers the PDP-1."

  • The first personal computer

    "In 1975 Ed Roberts coined the term personal computer when he introduced the Altair 8800. Although the first personal computer is considered to be the Kenbak-1, which was first introduced for $750 in 1971. The computer relied on a series of switches for inputting data and output data by turning on and off a series of lights.
    The Micral is considered the be the first commercial non-assembly computer. The computer used the Intel 8008 processor and sold for $1,750 in 1973."

  • The first digital computer

    US Federal Judge Earl R. Larson signed his decision that the ENIAC patent by Eckert and Mauchly was invalid and named Atanasoff the inventor of the electronic digital computer. The ABC was the first computer to use vacuum tubes

  • The first workstation

    "Although never sold the first workstation is considered to be the Xerox Alto, introduced in 1974. The computer was revolutionary for its time and included a fully functional computer, display, and mouse. The computer operated like many computers today utilizing windows, menus and icons as an interface to its operating system."

  • The first laptop or portable computer

    "The IBM 5100 is the first portable computer, which was released on September 1975. The computer weighed 55 pounds and had a five inch CRT display, tape drive, 1.9MHz PALM processor, and 64KB of RAM.The Osborne I was developed by Adam Osborne and weighed 24 pounds, had a 5-inch display, 64 KB of memory, two 5 1/4" floppy drives, and a modem. IBM PCD later released the IBM portable in 1984, it's first portable computer that weighed in at 30 pounds.

  • The first Apple computer

    "Steve Wozniak designed the first Apple known as the Apple I computer in 1976. The first computer company was the Electronic Controls Company and was founded in 1949 by J. Presper Eckert and John Mauchly, the same individuals who helped create the ENIAC computer. The company was later renamed to EMCC or Eckert-Mauchly Computer Corporation and released a series of mainframe computers under the UNIVAC name."

  • The first PC clone

    "The first PC clone was developed by Compaq , the "Compaq Portable" was release in March 1983 and was 100% compatible with IBM computers and software that ran on IBM computers."

  • The first multimedia computer

    "In 1992 Tandy Radio Shack becomes one of the first companies to release a computer based on the MPC standard with its introduction of the M2500 XL/2 and M4020 SX computers."
