Collecting Calculators: History of Calculators [Online]. Accessed 7/16/01: http://www.geocities.com/SiliconValley/Park/7227/. Quoting from the Website:
This site includes historical and collectible information for collectors of calculators. While our focus is on early electronic calculators of the 1960's and 1970's, we will also discuss some of the other types such as the larger electronic and electro-mechanical "monsters" like the Anita and the Monroes as well as the compact mechanical units like the Curta and Addiator. This site was the home for the no longer active International Association of Calculator Collectors -- a worldwide group of collectors who published the International Calculator Collector.
Nothing epitomizes modern life better than the computer. For better or worse, computers have infiltrated every aspect of our society. Today computers do much more than simply compute: supermarket scanners calculate our grocery bill while keeping store inventory; computerized telephone switching centers play traffic cop to millions of calls and keep lines of communication untangled; and automatic teller machines (ATM) let us conduct banking transactions from virtually anywhere in the world. But where did all this technology come from and where is it heading? To fully understand and appreciate the impact computers have on our lives and promises they hold for the future, it is important to understand their evolution.
This 10th anniversary issue of Creative Computing contains a large number of articles that are reflective on the previous 10 year's progress in the field of computers in education. Among other things, those 10 years span the introduction of the microcomputer into education. The issue contains an extensive article about David Ahl who started the publication. This article includes some of the history behind Ken Olsen's (one of the founders of, and president of Digital Equipment Corporation) often quoted statement: "I can't see any reason that anyone would want a computer of his own."

History of Computers (n.d.). Accessed 1/10/06.: http://www.maxmon.com/timeline.htm
The timeline for this view of computer history begins 350 million years ago, and then continues with carving on notches in bones about 30,000 to 20,000 BC. The timeline continues with many interesting articles. For example, there is a discussion of a wolf's jawbone more than 20,000 years old with fifty-five notches in groups of five. This bone, which was discovered in Czechoslovakia in 1937, is the first evidence of the tally system.

Redin, James. The Death of the Slide Rule [Online]. Accessed 7/15/01: http://www.dotpoint.com/xnumber/hp.htm. Quoting from the Website:
"Our object in developing the HP-35 was to give you a high precision portable electronic slide rule. We thought you'd like to have something only fictional heroes like James Bond, Walter Mitty or Dick Tracy are supposed to own."
As an example, consider a computer system costing US$1 million in 1967. To convert to dollars for the year 2000, divide by .194. The result is US$5.15 million.
Herbert Simon was one of the pioneers in the field of Computer and Information Science. His interests were wide ranging, and he contributed to many parts of the field. He is especially known for his contributions in Artificial Intelligence. He was awarded the 1978 Nobel Prize for his work in Economics. The Website listed above contains a copy of his 1987 article The Steam Engine and the Computer: What Makes Technology Revolutionary. This article suggests that (in 1987) the field of IT was still very young relative to how long it takes a major technology (such as the steam engine) to have a significant impact on the world.

Google has fully integrated the past 20 years of Usenet archives into Google Groups, which now offers access to more than 700 million messages dating back to 1981. This is by far the most complete collection of Usenet articles ever assembled and a fascinating first-hand historical account.
This site provides access to the history of many different types of computers as well as a large number of photographs. Quoting from the Website:The UNIVAC I (the name stood for Universal Automatic Computer) was delivered to the Census Bureau in 1951. It weighed some 16,000 pounds, used 5,000 vacuum tubes, and could perform about 1,000 calculations per second. It was the first American commercial computer, as well as the first computer designed for business use. (Business computers like the UNIVAC processed data more slowly than the IAS-type machines, but were designed for fast input and output.) The first few sales were to government agencies, the A.C. Nielsen Company, and the Prudential Insurance Company. The first UNIVAC for business applications was installed at the General Electric Appliance Division, to do payroll, in 1954. By 1957 Remington-Rand (which had purchased the Eckert-Mauchly Computer Corporation in 1950) had sold forty-six machines.
UVIVAC Memories [Online]. Accessed 2/20/02: http://www.fourmilab.ch/documents/univac/index.html. Quoting from the Website:
People who have used a 100 megabyte hard drive that weighed two and a quarter tons and cost more than US$130,000 in 1968 experience a special sense of wonder when tucking one of today's 2.1 gigabyte drives, just purchased for less than US$1000 and weighing less than half a kilo, into their pocket.
