Despite appearances, today's online world did not spring to life fully formed. Before they were made a major part of our lives, some pioneering computers either had to capture the public's imagination, establish what could be done by computers, or both.

Here, we'll look at some computers that played, and sometimes continue to play, a major role. Here they are:

  • [spoiler=The difference engine]

    Charles Babbage lost his knack for talking money out of the British government, which wanted a machine that could generate math tables, and so the computer revolution didn't begin in England in 1822. (Did you notice the 8 in that date?). Babbage designed an amazing computer, it just did not get built until recently, as replica mechanical computers have since been constructed using Babbage's original, complex blueprints. They work perfectly.[/spoiler]

  • [spoiler=ENIAC]

    Being programmable and performing 357 multiplication operations per second, the U.S. Army's Electronic Numerical Integrator And Computer (ENIAC) hinted at what a computer could do when it was unveiled in 1946. However, it weighed 30 tons, used 17,478 vacuum tubes, consumed 150 kilowatts, and programming involved patch cables and switches.[/spoiler]

  • [spoiler=IBM system/360]

    With an extensive set of standard peripherals and a range of compatible models at different price points, the S/360 tapped a huge pent-up demand for business computers when IBM brought it out in 1964. Its popularity provided the economic foundation for the modern computer industry.[/spoiler]

  • [spoiler=Datapoint 2200]

    One of the first single-user computers on the market when it came out in 1970 from the now-defunct Computer Terminal Corp., the Datapoint 2200 lives on in every PC today. CTC convinced fellow start-up Intel to reduce the machine's processor to a single chip, to combat system heating. Intel ended up adding the chip to its catalog, founding today's "Intel dynasty" of PC microprocessors. (System heating, alas, remains a problem.)[/spoiler]

  • [spoiler=Xerox PARC Alto]

    A single-user computer with a graphical interface with windows and icons, a mouse for cursor control, a local hard drive, and an Ethernet connection to the rest of the office and/or world--that probably describes the machine you're using right now. Those features first came together in the Alto, an experimental machine developed at the Xerox Palo Alto Research Center (PARC) in 1974. Xerox, however, never had the nerve to put the Alto on the market.[/spoiler]

  • [spoiler=TRS-80]

    Introduced in 1977, Radio Shack figured its original production run of 3,000 could be used as cash registers if they didn't sell. But sales exceed that projection by a factor of 80. One of the first machines whose documentation was intended for non-geeks, the widespread adoption of the "Trash-80" led to the first third-party mass personal software market. For the first time, non-geeky high school kids could write programs and make a computer do their bidding.[/spoiler]

  • [spoiler=Apple II]

    Introduced by Apple Computer in 1977 and kept on the market for an unprecedented 15 years, the Apple II demonstrated conclusively that there was a mass personal computer market. Its pioneering use of color graphics also won it wide following in the education market--and disdain in the business market, which saw color as frivolous.[/spoiler]

  • [spoiler=IBM PC]

    It was hardly the fastest or slickest microcomputer when it came out in 1981, but it did have those three initials, and it established hardware and software standards in a market whose growth had previously been stymied by fragmentation among competing architectures. The clone, software, and peripheral markets that sprang up around the PC led directly to today's personal computer ecosystem.[/spoiler]

  • [spoiler=Apple Macintosh]

    The "computer for the rest of us" raised the bar for the rest of the personal computer industry when it came out in 1984 by abandoning the command-line interface (as used by the PC's MS-DOS operating system and essentially everyone else) for a graphical user interface. Not only that, it was commercially successful doing so.[/spoiler]

  • [spoiler=IBM Roadrunner]

    The title of fastest supercomputer has become hard to retain for long, but the current champ is also notable for being the first machine with sustained throughput exceeding a petaflop -- more than a quadrillion floating point operations per second. Physically, it's bigger than the ENIAC computer unveiled in 1946, but, if history is any guide, we'll see equivalent power on a desktop in a few decades[/spoiler]
