12. 1955 11:45pm on Oct. 2, ENIAC retired AT&T Bell: first fully transistorized computer TRADIC Contained 800 transistors instead of vacuum tubes Transistors: cold, high efficiency amplifying devices invented at Bell Lab. Used only 100 watts or 1/20 th power of vacuum tube computers

13. 1956 First general purpose, programmable computer built with transistors Hosted early imaginative tests:  Western movie shown on TV  3-D tic-tac-toe  Maze which mouse found martinis and became inebriated Era of Magnetic disk storage dawned  IBM 350 storage for RAM of Accounting and Control  5 million bytes of data

14. 1958 Jack Kilby Robert Noyce Integrated Circuit Two companies cross licensed creating global market now worth $1 trillion a year IC’s replaced transistors IC connected wiring onto a single chip made of semiconductor material

15. 1960 IBM 7090 First commercial transistorized computer built Fastest computer in the world

16. 1961  First commercially IC’s available  All computers now made using IC  Original IC size of pinkie with 1 transistor  Today’s IC’s smaller than penny with 125 million transistors

17. 1962-1964 Steve Russell: “Spacewar” Douglas Engelbart: created more user friendly computers Engelbart: invented the computer mouse to use with windows (not patentable)

18. 1969  Grandfather to Internet  Four computers involved  UCLA and Stanford’s first attempt failed  Resulted in better protocol called Transmission Control Protocol/ Internet Protocol (1982)

19. ARPnet continued… E-mail: (1971) Telnet: remote connection for controlling computer(1972) File Transfer (FTP): allowed information to be sent in bulk (1973)

20. 1973 (or 1976?)  Robert Metcalfe (Xerox)  Several computers connected within one building  Motivated by current development of first laser printer  Ethernet is now most widely LAN used

21. 1974  First ad for PC published in magazine  Ad featured Intel 8008 “Scelbi”  $565 with 1k of programmable memory  $2,760 for extra 15k of memory

22. 1975  8080 CPU, 256 byte RAM  “assembly required”  2 programmers realized need for software: The Altair “Worlds First Minicomputer Kit” Paul Allen and Bill Gates

23. BASIC  Altair kickstarted home computer revolution  Within 6 weeks, Allen and Gates compiled BASIC for Altair  BASIC required 4096 bytes of memory (only 256 available)  4k memory board was created but poorly designed (Bob Marsh)

24. 1975 continued Allen and Gates started Microsoft IBM 5100 or “Project Mercury” released  first portable computer  $10,000 price

25. 1976  5 ¼” floppy developed by Alan Shugart for Wang Laboratories  Needed for desktop computers

26. 1979 WordStar : first commercially successful word processing program Other early word processing programs include: Electric Pencil, Apple Write I, Word, Word Perfect, Scripsit, Samnna III VisiCalc First computer spreadsheet (ran on Apple II) By fall, team wrote for Tandy, TRS-80, CommodorePET and Atari 800 $100 Sold to Lotus Development – became Lotus 1-2-3 by 1983
