Transistor, 1947

Ran cooler, used less power, worked faster than vacuum tube, did not burn out as often

First computer with transistor – 1956 By 1960 – all computers used transistors.

1952 – 1960

1953 The IBM 701 becomes available to the scientific community. A total of 19 are produced and sold.

1954 IBM produces and markets the IBM 650. More than 1,800 of these computers are sold in an eight-year span

1955 Bell Labs introduces its first transistor computer. Transistors are faster, smaller and create less heat than traditional vacuum tubs, making these computers more reliable and efficient.

1955 The ENIAC is turned off for the last time. It’s estimated to have done more arithmetic than the entire human race had done prior to 1945.

1956 IBM’s 3005 RAMAC is the first computer to be shipped with a hard disk drive.

1957 IBM announces it will no longer be using vacuum tubes and releases its first computer that had 2000 transistors.

1957 Russia launches the first artificial satellite, named sputnik. 1958 The first integrated chip is first developed by Robert Noyce of

Fairchild Semiconductor and Jack Kilby of Texas Instruments. The first microchip was demonstrated on September 12, 1958.

1960 – 1971

1961 General Motors puts the first industrial robot – the 4,000 pound Unimate – to work in a New Jersey factory.

1963 Doug Engelbart invents and patents the first computer mouse. 1963 The American Standard Code for Information Interchange (ASCII) is

developed to standardize data exchange among computers. 1964 Dartmouth University’s John Kemeny and Thomas Kurtz develop Beginner’s

All-purpose Symbolic Instruction Language (BASIC). 1965 Ted Nelson coins the term "hypertext," which refers to text that is not

necessarily linear. 1967 IBM creates the first floppy disk. 1969 AT&T Bell Laboratories develop Unix. 1969 The U.S. Department of Defense sets up the Advanced Research Projects

Agency Network (ARPANET ) this network was the first building blocks to what the internet is today.

1970 Intel announces the 1103, a new memory chip containing more than 1,000 bits of information. This chip is classified as random-access memory (RAM).

1970 Intel introduces the first microprocessor, the Intel 4004. 1971 The first 8" floppy diskette drive was introduced 1971 The first laser printer is developed at Xerox PARC.

1972 – 1980

1972 Atari releases Pong, the first commercial video game. 1972 The compact disc is invented in the United States. 1973 Robert Metcalfe creates the Ethernet at the Xerox Palo Alto Research Center

(PARC). 1974 Intel’s improved microprocessor chip, the 8080 becomes a standard in the

microcomputing industry. 1974 IBM develops SEQUEL, which today is known as SQL today. 1975 MITS ships one of the first PCs, the Altair 8800 with one kilobyte (KB) of memory.

The computer is ordered as a mail-order kit for $397.00 1975 Paul Allen and Bill Gates write the first computer language program for

personal computers, which is a form of BASIC designed for the Altair. 1975 Steve Wozniak and Steve Jobs co-found Apple Computers. 1976 The first 5.25-inch floppy disk is invented. 1976 Microsoft introduces an improved version of BASIC. 1976 The Intel 8086 is introduced. 1978 The 5.25-inch floppy disk becomes an industry standard. 1979 Texas Instruments enters the computer market with the TI 99/4 personal

computer that sells for $1,500. 1979 Atari introduces a coin-operated version of Asteroids. 1979 More then half a million computers are in use in the United States. 1979 The Motorola 6800 is released and is later chosen as the processor for the

Apple Macintosh.

Future Computers

Few argue that the next generation of computers will be nearly invisible, meaning that they will blend in with everyday objects. Flexible ink-like circuitry will be printed onto plastic or sprayed onto various other substrates, such as clothes.
