600 BCE
  - Abacus - Commonly credited to the Chinese but may have originated in the Middle east.
    The oldest surviving abacus was used in 300 B.C. by the Babylonians.
    May have evolved from counting tables on a simple stone slab with incised parallel lines around 3000 BCE.
1925 - Vannevar Bush at MIT develops analog computers, culminating in the
   Differential Analyzer in the early 1940's
1945 - Bush authored the article "As We May Think" in the Atlantic Monthly
    in which he first proposed his idea of the Memex machine, which would help people
    sort through the enormous amount of published information available throughout the world.
1947
  John Bardeen, Walter Brattain,  and William Shockley invent the transistor.
  Actually patents on field-effect transistors (FETs) were filed by
  Physicist Julius Edgar Lilienfeld (Canada) in 1925 and  Oskar Heil (Germany) 1934.
  However high-quality semiconductor materials were not available at the time,
  so no working prototype was built.
1952 -  Core memory - Jay Forrester, MIT
1958 
  - The integrated circuit (IC) is invented by Jack St. Clair Kilby of Texas Instruments,
    beating Robert Noyce of Fairchild Semiconductor who independently invented one in 1959.
    Noyce went on to cofound Intel. 
   - FLOW-MATIC, originally known as B-0 , was the first English-like programming language.
     It was developed for the UNIVAC I at Remington Rand under Grace Hopper.
     It was the first machine-independent programming language,
     and led to the development of COBOL.

1963

  -  Douglas Engelbart patents the mouse while at
     Stanford Research Institute (SRI).
 
 
 - Ivan Sutherland develops Sketchpad using a light pen and bitmap display to make
  CAD like drawings on a computer screen with a TX-2 computer as part of his PhD thesis at MIT.
  - It takes 20 years for these two technologies to be combined into a personal
    computer (Apple Lisa, Xerox Star and Macintosh)
1964
  -  John George Kemeny and Thomas Eugene Kurtz develop the BASIC 
        (Beginner's All-purpose Symbolic Instruction Code) language at Dartmouth.
1965 
  - Digital Equipment produced the first PDP-8 minicomputer,
    the first production computer to use integrated circuits.
  -  Time sharing systems by companies like GE's GEISCO and Tymshare,
     using terminals connected to computers like the SDS 940, the PDP-10, and the IBM 360
     with Bell 103 (110 baud) modems to access things like BASIC programming.
  - Gordon E. Moore (Intel co-founder) describes "Moore's law": The number of transistors
    that can be placed on an IC will double approximately every two years.
1968-9
  - Bell Labs scientists start work on the C programming language and new OS
    for the DEC PDP-7 with 8K 18-bit words of memory .
1970
  - Ken Thompson and Dennis Ritchie at Bell Labs develop UNIX operating system (OS).
   See Dennis Richie
   A portable, multi-tasking and multi-user in a time-sharing system running on a DEC PDP-7 
1972 
  - INTEL released the 200 kHz 8008, an 8 bit version of the 4004
  - Clive Sinclair is the first (August 1972) to bring a pocket   calculator
    TI and HP follow shortly
  - Arcade video game Pong developed
  - Xerox starts project "Alto", to build a personal computer at
    the Palo Alto Research Center (PARC).
The mouse and bitmap displays had been invented 10 or more years earlier but researchers such as Alan Kay, Larry Tesler, Dan Ingalls and others developed the Graphical User Interface (GUI) using the mouse to point-and-click and drag-and-drop icons (small intuitive pictograms representing a function or data). What You See Is What You Get (WYSIWYG) text editing was also part of their system.
They develop the icon based graphical user interface later popularized by the Apple Macintosh (1984) and Microsoft Windows 3 (1990) - Bell Labs Programing Language C used internally. 1973 - E-mail standards for exchanging messages over Arpanet are created by Ray Tomlinson of BBN. Timesharing systems in the early 60's had programs to exchange text messages with users. - A Canadian firm, Automatic Electronic Systems, introduced the world's first programmable word processor with a video screen" the AES 90. Wang, VYDEC, and Lexitron follow shortly - Steve Wozniak builds a "blue box" tone generator to make free phone calls and sells them in the dorm at UC Berkeley. - At Xerox PARC, Alan Kay proposes they build a portable personal computer: the Dynabook - The UNIX OS is rewritten in C (It was previously in assembly language) 1974 - The CP/M (Control Program/Monitor also: Control Program for Microcomputers) designed by Digital Research /John Torode and Gary Kildall for the 8080 chip. - The Z-80, 8 bit processor is designed by Zilog Corp. - Intel introduced the 8080 for the purposes of controlling traffic lights, but it was to find fame later as the processor for the Altair. - Motorola introduces the 6800 CPU, an early 8 bits microprocessor that will be embedded in a lot of industrial devices. - First Use of term "Internet" appears in a conference paper by Vinton Cerf and Bob Kahn. 1975 - Ed Roberts (USA) starts to ship the MITS ALTAIR 8800, with the Intel 8080 chip. It contains a memory of 256 bytes, a row switches in stead of a keyboard and leds that serves as a read out in stead of a monitor. It's S-100, 100 pin bus becomes an industry standard. - Micro-Soft is founded by Bill Gates and Paul Allen. Their first product is a version of BASIC for the ALTAIR. 1976 - The 6501 and 6502 micro processor was developed by MOS Technology Corporation. 1977 - Dennis C.

See: Did Apple license Xerox PARC's GUI at quora.com - Apple starts development on the Macintosh and in 1980 hires Larry Tesler from Xerox PARC. 1980 - Seagate Technology introduces the first hard disk drive for microcomputers, the ST506. 5 Mb. The access time is low: 180 - 240 milliseconds - I define the standard for personal computers at AT&T Z/80 processor, soft sectored 8 in floppy disk and CP/M operating system - HP, Xerox and others come out with CP/M based PCs using the Zilog Z80 microprocessor. CP/M ported to Apple II with a Z80 processor board. 1981 - First IBM PC - 4.77 MHz 8 bit 8088 CPU of Intel 64KB RAM, 40KB ROM, one 5.25-inch floppy drive (160KB capacity) for $1,565. There are various stories about why IBM used DOS (Disk Operation System) instead of CP/M The most common is IBM approached Digital Research (DR) to use their CP/M operating system. Gary was not available and Mrs. Kildall refused to sign the contract/non-disclosure. See: Switch from CP/M to DOS by Bill Gates. History of MS-DOS at DigitalResearch.biz - Microsoft bought all rights to an OS from Seattle Computer Products then called QDOS assumingly meaning Quick and Dirty Operating System, and the name PC-DOS is adopted. Story is that part of QDOS was copied from CP/M and DR eventually won a settlement. - The original DOS architecture had a 640 KB memory limit. Bill Gates says "640K ought to be enough for anybody." - Osborne 1 is the first "portable" computer - HP 125 1981 Xerox releases the Star (Xerox 8010 Information System) with the Pilot operating system Released after 10 years of research with their Alto system used internally It had a graphical user interface using the mouse driven desktop metaphor. 2 years before the microsoft mouse and Apple LISA It was too expensive, over $10,000 and didn't succeed commercially 1982 - ARPA enacts TCP (Transmission Control Protocol) and Internet Protocol (IP) and the DOD adopts it as its standard. - Xerox introduces the STAR based on ALTO for $16,000 The first WIMP environment (Window, Icons, Mouse and Pull-down menus) PC. - Time Magazine eschewed its Man of the Year Award in favor of Machine of the Year: - Ashton Tate releases the database program dBase II. - Sun Microcomputer corporation is founded, by Scott McNealy, Bill Joy and others.
