                                     the inventor of logarithms, developed
                                     an ingenious arithmetic trick— not as
                                     remarkable as logarithms, but very

                                     and was the result of a joint effort of
                                     two Englishmen, Edmund Gunter and
                                     the Reverend William Oughtred. This
                                     slide rule based on Napier's
                                     logarithms was to become the first

       Edmund Gunter and William     subtraction were figured out by
       Oughtred                      physical distance. This invention was
                                     dormant until 1850 when a French
                                     Artillery officer Amedee Mannheim
                                     added the movable double sided
                                     cursor, which gave it its appearance

1866                                   numbering book pages, they were
       Sholes and Carlos Glidden and   inspired to build a machine that could

                                 In Boston, Massachusetts, Alexander
                                 Graham Bell invented the telephone.
                                 Thomas Watson fashioned the device
                                 itself; a crude thing made of a
                                 wooden stand, a funnel, a cup of acid,
       Telephone                 and some copper wire. But these
1876                             simple parts and the equally simple
       Alexander Graham Bell     first telephone call —"Mr. Watson,
                                 come here, I want you!" — belie a

                                 The device consisted of a cylindrical
                                 drum wrapped in tinfoil and mounted
                                 on a threaded axle. A mouthpiece
                                 attached to a diaphragm was
                                 connected to a stylus that etched

       Thomas Edison             replaced with a "reproducer" that
                                 used a more sensitive diaphragm.
                                 Edison recited "Mary Had a Little

                                     employed as a "wireless telegraph",

       Guglielmo Marconi             radio's ability to broadcast messages
                                     simultaneously to multiple locations,
                                     at first using the dots-and-dashes of
                                     telegraphic code, and later in full

                the motion

                But in a short time
                the movies proved
                to be good enough

                might be added
                that the motion
                picture held the
                phonograph in
                such low esteem
                that for years it
                would not speak.

                long history of
                efforts to add
                sound, the success
                of the silent movie
                was the great
                obstacle to

                            Could there exist, at least in principle,
                            a definite method or process by which
                            it could be decided whether any given
                            mathematical assertion was
                            provable?

                            To answer such a question needed a
                            definition of 'method' which would be
                            not only precise but compelling. This
                            is what Turing supplied. He analysed
                            what could be achieved by a person
                            performing a methodical process, and
                            seizing on the idea of something done
       The Turing Machine   'mechanically', expressed the analysis
1936                        in terms of a theoretical machine able
       Alan Turing          to perform certain precisely defined
                            elementary operations on symbols on
                            paper tape. He presented convincing
                            arguments that the scope of such a
                            machine was sufficient to encompass
                            everything that would count as a
                            'definite method.' Daringly he
                            included an argument based on the
                            transitions between 'states of mind' of
                            a human being performing a mental
                            process.

                                                            had reduced his RAM cell to a single

                                developing custom chips for its new

       Hoff at Intel            with a single specific function, Hoff
                                proposed that Intel develop a more

                                 date, IBM produced only mini and
                                 mainframes). They didn't really know
1981   IBM PC with DOS & Intel   that they wanted and they didn't
                                 think for one second that producing
                                 microcomputers was a profitable
                                 business (who would have thought!)!

                                 Computer Faire in 1981, the Osborne 1
       Portable computer—        was the brain child of Adam Osborne,
                                 a computer columnist, writer, and
                                 engineer. It was co-developed with
1981   Osburne I                 Lee Felsenstien, and Lee designed it.
                                 The goal was a truly integrated
       Adam Osborne              computer that could go wherever the
                                 user wanted to. The machine was
                                 shipped as a full package including all
                                the hardware and software a user
                                could need including: 64K RAM, Z-80
                                CPU, 5" CRT, two floppy drives,
                                keyboard, serial ports, CP/M
                                operating system, WordStar,
                                SuperCalc, and two versions of
                                BASIC: CBASIC and MBASIC. The
                                machine also had the ability to
                                connect with scientific equipment via
                                a built-in IEEE-488 interface, and
                                could run an optional external
                                monitor via the built-in port. Not only
                                was the machine complete, it was
                                cheap - $1795.

                                Once upon a time there were lots of
                                disk-repair utilities for the Mac.
                                Symantec made Norton Utilities,
                                Central Point made MacTools, and
                                Fifth Generation made Public
                                Utilities. MacTools and Public
                                Utilities could scan disks during idle-
                                time. MacTools had TrashBack, the
                                best way to undelete files I've ever
                                seen, and could boot itself from a
                                RAM disk. What did Norton have? It
1982   Norton Utilities         had a bunch of components you don't
                                find in the current release, including a
                                Directory Assistance utility that
                                improved Open/Save dialogs, a
                                backup utility, and a utility for
                                duplicating floppy disks. The last item
                                is as obsolete as Fast Find, but I think
                                many users would enjoy having the

                             Computer released the first program

                             time for consumers: the Macintosh
                             was newer, had fancy fonts and
                             styles, had a wonderfully clear
                             display, but all the software that was
       Apple Works           available for it was a simple word
1984                         processor called "MacWrite" and a
       Apple                 paint program called "MacPaint." On
                             the other hand, AppleWorks made the
                             old Apple II more capable than the
                             Mac, since it combined a word
                             processor, a database, and a
                             spreadsheet, and it let you create in
                             any of those "modules" and move the
                             information into either of the others.

                             called "Apple Pie", and he began work
                             on it in 1982. Lissner took two years
                             to complete his program, and did it
1987   AppleWorks & Claris   entirely in assembly language to
                             achieve better speed. He wrote
       Rupert Lissner        versions of the program to work on
                             both the Apple II and Apple III
                             computers, making use of the same

                             Pie files created on an Apple II could
                             be used on an Apple III, and vice-

                                                     it became available. In those days, if
                                                     you needed typesetting equipment,
                                                     you went to Acme Typesetters, and
                                                     they would sell you an Acme system
                                                     with an Acme output device. Then you
                                                     would follow at least two weeks of
                                                     training to learn how to use the
                                                     system. The Acme system would be
       Postscript                                    incompatible with equipment from
1985                                                 any other manufacturer. In most
       Adobe                                         cases, it would even be difficult or
                                                     impossible to exchange data with

                                                     acceptable to the nerds that bought

                               Microsoft first began development of
                               the Interface Manager (subsequently
                               renamed Microsoft Windows) in
                               September 1981. Although the first
                               prototypes used Multiplan and Word-
                               like menus at the bottom of the screen,
                               the interface was changed in 1982 to
                               use pull-down menus and dialogs, as
                               used on the Xerox Star. Microsoft
                               finally announced Windows in
       Windows 1.0             November 1983, with pressure from
1985                           just-released VisiOn and impending
       Microsoft               TopView. Windows promised an
                               easy-to-use graphical interface,
                               device-independent graphics and
                               multitasking support. The
                               development was delayed several
                               times, however, and the Windows 1.0
                               hit the store shelves in November
                               1985. The selection of applications
                               was sparse, however, and Windows
                               sales were modest.

                         for sale for $25. I looked it over. The
1985   Laptop computer   owner pointed out rather flatly that it
                         ran DOS and was fully functional. His
       Toshiba           spouse was much more enthusiastic
                         about my investigations, adding how
                         useful it had been.

                         Plus was the answer to complaints
                         that the original Mac was not

                         increased the RAM to 1 MB
                         (expandable to 4 MB). It was the first

                        The "Brain" virus is probably the
                        earliest MS-DOS virus. At one time it
                        was the most widespread of PC viral
                        programs.
                        Brain is a boot sector infector,
                        somewhat longer than some of the
                        more recent BSIs. Brain occupies
                        three sectors itself, and, as is usual
1987   Computer virus   with BSIs, repositions the normal
                        boot sector in order to "mimic" the
                        boot process. As the boot sector is only
       Brain            a single sector, Brain, in infecting a
                        disk, reserves two additional sectors
                        on the disk for the remainder of itself,
                        plus a third for the original boot
                        sector.

                        Software engineer Tim Gill founded
                        Quark in 1981, producing the first
                        word processor for the Apple II
                        computer. Gill named the company

                        proposed as a building block for all

               In 1987 Canon USA Inc. released a

               This computer was targeted at low-
               level clerical worked such as
               secretaries. After six months on the
               market and with 20,000 units sold,
       Cat     Canon discontinued the Cat. The Cat
               featured an innovative text based user
       Canon   interface that did not rely upon a
               mouse, icons, or graphics. The key
               person behind the Cat was Mr. Jef
               Raskin, an eclectic gadgeteer, who
               began the design of the Cat during his

               On the evening of November 2, 1988,
               a self-replicating program was
               released upon the Internet (1) This
               program (a worm) invaded VAX and
               Sun-3 computers running versions of
1988           Berkeley UNIX, and used their
       Worm    resources to attack still more
               computers (2). Within the space of
               hours this program had spread across
               the U.S., infecting hundreds or
                                                  thousands of computers and making
                                                  many of them unusable due to the

                            Touchpads are relative motion
                            devices. That is, there is no
                            isomorphism from the screen to the
                            touchpad. Instead, relative motion of
                            the user's fingers causes relative
                            motion of the cursor. The buttons
                            below or above the pad serve as
       Touch sensitive      mouse standard buttons. You can also
       pad/touchpad         click by tapping your finger on the
                            touchpad, and drag with a tap
                            following by a continuous pointing
                            motion (a click-and-a-half). Some
                            touchpads also have "hotspots":
                            locations on the touchpad that
                            indicate user intentions other than
                                  pointing. For example, on certain
                                  touchpads, moving your finger along
                                  the right edge of the touch pad will
                                  control the scrollbar and scroll the
                                  window that has the focus vertically.
                                  Moving the finger on the bottom of
                                  the touchpad often scrolls in
                                  horizontal direction. Some touchpads
                                  can emulate multiple mouse buttons
                                  by either tapping in a special corner
                                  of the pad, or by tapping with two or
                                  more fingers.

                                    FutureWave for 4 years with a total
                                    investment of $500,000 and the idea
                                    of having access to the resources of a
1992                                larger company to help us get
       Macromedia                   FutureSplash established in a market
                                    that was full of competitors and
                                    growing slowly seemed like a good
                                    one. So in December of 1996, we sold
                                    FutureWave Software to Macromedia
                                    and FutureSplash Animator became

                                    In 1993, Apple Computer Inc.
                                    introduced the world to the first PDA,
                                    the Newton®. They were dubbed
                                    PDAs (personal digital assistants) by
                                    John Sculley, former chairman of
                                    Apple Computer Inc, and were sold as
                                    the ultimate information appliance.
                                    Sculley predicted PDAs would become
                                    ubiquitous tools that would hold

       Apple                        receive data wirelessly. Although, the
                                    Newton was not able to deliver all of
                                    those features at the time it was
                                    released.
                                    For the next three years, PDA sales
                                    dwindled, and were almost off the

                                    Then, in March 1996, Palm™, Inc.
                                    delivered the industry's first truly
                                    compelling handheld computer, the

                              instant, anytime access to schedules,
                              important phone numbers, to-do lists

                              met with tremendous acceptance.
                              Mobile, busy people embraced the
                              small and powerful Palm™

                   In the summer of 1992,
                   they emerged with a
                   working demo, an

            20th        events will stand out in
                        the history of personal
2006   anniversary of   computers: the advent
        the MacPlus     of the microprocessor
                        which drove prices of
                        computers down to the
                        point where
                        individuals could buy
                        them and led to the
                        first flowering of the
                        present computer
                        revolution, the
ascendancy of the
software industry and
the shift from "users
will program them" to
"users will run
software packages",
the Mac interface and
its followers which
brought the benefits of
computers to a far
broader audience and
fundamentally
changed the way we
use computers of all
sizes and software of
all kinds, and (to tread
on dangerous ground
since the event is
relatively recent) the
blossoming of the
Internet. To sum up the
history: cheap
hardware, application,
software, human
interface, & internet
