An Illustrated History of Computers

_________________________________________________

John Kopplin © 2002

The first computers were people! That is, electronic computers (and the earlier mechanical computers) were given this name because they performed the work that had previously been assigned to people. "Computer" was originally a job title: it was used to describe those human beings (predominantly women) whose job it was to perform the repetitive calculations required to compute such things as navigational tables, tide charts, and planetary positions for astronomical almanacs. Imagine you had a job where hour after hour, day after day, you were to do nothing but compute multiplications. Boredom would quickly set in, leading to carelessness, leading to mistakes. And even on your best days you wouldn't be producing answers very fast. Therefore, inventors have been searching for hundreds of years for a way to mechanize (that is, find a mechanism that can perform) this task.

This picture shows what were known as "counting tables" [photo courtesy IBM]

A typical computer operation back when computers were people.

The abacus was an early aid for mathematical computations. Its only value is that it aids the memory of the human performing the calculation. A skilled abacus operator can work on addition and subtraction problems at the speed of a person equipped with a hand calculator (multiplication and division are slower). The abacus is often wrongly attributed to China. In fact, the oldest surviving abacus was used in 300 B.C. by the Babylonians. The abacus is still in use today, principally in the far east. A modern abacus consists of rings that slide over rods, but the older one pictured below dates from the time when pebbles were used for counting (the word "calculus" comes from the Latin word for pebble).

A very old abacus

A more modern abacus. Note how the abacus is really just a representation of the human fingers: the 5 lower rings on each rod represent the 5 fingers and the 2 upper rings represent the 2 hands.

Gateway unveils 14-inch TC7306u and TC7307u laptops

We can't say for certain what's gotten into Gateway this year, but it's on a roll. The company's MD and UC families, which were introduced at CES, earned high praise from reviewers and came in at very respectable price points. Now, the outfit is expanding things further with the 14-inch TC line, which is currently comprised of the TC7306u and TC7307u. Designed to hit that sweet spot between a full blown 15-incher and an ultraportable, these media-centric lappies get going at $649.99 and tip the scales at 5.3 pounds. Each one sports a 1.3 megapixel webcam, WiFi, gigabit Ethernet, a 1,366 x 768 resolution panel, a built-in multicard reader and three USB 2.0 ports. You'll also find a variety of colors, Intel's Core 2 Duo CPUs, a dual-layer DVD writer and a 6-cell Li-ion battery. Nah, you haven't missed anything out of the ordinary, but these two don't seem half bad for handling basic tasks without spending a bundle. Full release is after the break.

ASUS begins shipping ultra-longevous Eee PC 1000HE

ASUS' Eee PC 1000HE, which managed to garner some pretty high praise amongst reviewers, is now shipping out to eager buyers. For those that missed it, this here netbook sports a 1.66GHz Atom N280 and a high-capacity battery that could last up to 9.5 hours under perfectly ideal conditions. And for under $400, how in the world can you complain with that? If you too have received your tracking number, feel free to gloat about it in comments below. Might want to hold the actual digits close to your chest, though -- we hear netbook interceptions are on the rise.

Inspiron Mini 10 finally shows up at Dell's website

In one of the most bizarre sequences of events we can recall, Dell's Inspiron Mini 10 has finally arrived on its maker's website. And this is after being briefly (and we stress "briefly") unveiled in a 3- x 3-foot cubical at CES, being impersonated at Tecso by the smaller Mini 9 and showing up early on QVC. Yeah, weird. At any rate, we knew that the Round Rock powerhouse was looking to offer this pup up for sale starting on the 26th, so we figure now is a perfect time to host up a holding place in order to get people informed. As we'd heard, it'll sport a 10.1-inch display, 802.11b/g WiFi, optional Bluetooth 2.1, HDMI out, an external DVD drive, upwards of 160GB of HDD space, 1GB of RAM, a keyboard that's 92 percent the size of a standard laptop (that's the same as on ASUS' Eee PC 1000HE, by the way), a multitouch trackpad, 720p media playback, optional WWAN, an internal TV tuner and your choice of a 3-cell (3 hours) or 6-cell (6.5 hours) battery. Yummy!

ASUS experimenting with Android-based netbook

We'd already heard that ASUS was at least considering using Android on its Eee PC netbook, and seen it wrangled onto one unofficially (see above), but ASUS's Samson Hu has now offered a few more details that indicate just how serious the company is about the XP/Linux alternative. Apparently, ASUS has already allocated a team of engineers to work on the Android-based netbook, which Hu says could be ready by the end of the year, although the company isn't committing to actually releasing a product until it sees how things pan out. No further word on ASUS's other Android experiments, unfortunately, but it seems safe to bet that ASUS is devoting even more attention to those, at least if its latest timeline is any indication.

NVIDIA Ion platform to support VIA Nano processors this year

It's pretty clear NVIDIA already has some big plans for its new nettop / netbook-specific Ion platform, and it looks like its reach is about to get broader still, with company president Jen-Hsun Huang reportedly confirming that the platform will also support VIA's Nano processor by the end of the year. As you may recall, the two companies had been in off and on talks about a partnership last year before things finally fell though in November, and there was even a point where it seemed like NVIDIA might actually acquire VIA. No word from Intel on this latest development, although it doesn't seem like it'll be affecting the Atom's status as the go-to processor in the short term. There's also unfortunately no indication as to exactly what sort of VIA-powered, Ion-based systems we can expect to see, although it certainly wouldn't be a surprise if they followed the Ion / Atom combo and went with a nettop first.

1945 - John W. Mauchly and J. Presper Eckert built ENIAC at U of PA for the U.S. Army
1946 - Mauchly and Eckert start Electronic Control Co., received grant from National Bureau of Standards to build a ENIAC-type computer with magnetic tape input/output, renamed UNIVAC in 1947 but run out of money, formed in Dec. 1947 the new company Eckert-Mauchly Computer Corporation (EMCC).
1948 - Howard Aiken developed the Harvard Mark III electronic computer with 5000 tubes
1948 - U of Manchester in Britain developed the SSEM Baby electronic computer with CRT memory
1949 - Mauchly and Eckert in March successfully tested the BINAC stored-program computer for Northrop Aircraft, with mercury delay line memory and a primitive magentic tape drive; Remington Rand bought EMCC Feb. 1950 and provided funds to finish UNIVAC
1950- Commander William C. Norris led Engineering Research Associates to develop the Atlas, based on the secret code-breaking computers used by the Navy in WWII; the Atlas was 38 feet long, 20 feet wide, and used 2700 vacuum tubes
1951 - S. A. Lebedev developed the MESM computer in Russia
1951 - Remington Rand successfully tested UNIVAC March 30, 1951, and announced to the public its sale to the Census Bureau June 14, 1951, the first commercial computer to feature a magnetic tape storage system, the eight UNISERVO tape drives that stood separate from the CPU and control console on the other side of a garage-size room. Each tape drive was six feet high and three feet wide, used 1/2-inch metal tape of nickel-plated bronze 1200 feet long, recorded data on eight channels at 100 inches per second with a transfer rate of 7,200 characters per second. The complete UNIVAC system weighed 29,000 pounds, included 5200 vacuum tubes, and an offline typewriter-printer UNIPRINTER with an attached metal tape drive. Later, a punched card-to-tape machine was added to read IBM 80-column and Remington Rand 90-column cards.
1952 - Remington Rand bought the ERA in Dec. 1951 and combined the UNIVAC product line in 1952: the ERA 1101 computer became the UNIVAC 1101. The UNIVAC I was used in November to calculate the presidential election returns and successfully predict the winner, although it was not trusted by the TV networks who refused to use the prediction.
1954 - The SAGE aircraft-warning system was the largest vacuum tube computer system ever built. It began in 1954 at MIT's Lincoln Lab with funding from the Air Force. The first of 23 Direction Centers went online in Nov. 1956, and the last in 1962. Each Center had two 55,000-tube computers built by IBM, MIT, AND Bell Labs. The 275-ton computers known as "Clyde" were based on Jay Forrester's Whirlwind I and had magnetic core memory, magentic drum and magnetic tape storage. The Centers were connected by an early network, and pioneered development of the modem and graphics display.

History of Computers

The development of the modern day computer was the result of advances in technologies and man's need to quantify. Papyrus helped early man to record language and numbers. The abacus was one of the first counting machines. . Some of the earlier mechanical counting machines lacked the technology to make the design work. For instance, some had parts made of wood prior to metal manipulation and manufacturing. Imagine the wear on wooden gears. This history of computers site includes the names of early pioneers of math and computing and links to related sites about the History of Computers, for further study. This site would be a good Web adjunct to accompany any book on the History of Computers or Introduction to Computers. The "H" Section includes a link to the History of the Web Beginning at CERN which includes Bibliography and Related Links.
