82. DACDjr, February 23, 2002, “Electrical Numerical Integrator And Computer” John Mauchly and J. presper eckert would have made http//inventorsmuseum.com/CharlesBabbage.htm Charles Babbage proud with their invention of the ENIAC. http://www.lodinet.com/pappy/dacd_feb23i.htm

Electrical Numerical Integrator and Computer by DACDjr ENIAC, the "Electrical Numerical Integrator and Computer," was not the first computer developed, but it opened the door for everything that follow. Weighing in at over 30 tons with 18,000 vacuum tubes, 1500 relays and hundreds of resistors, capacitors and inductors it was the first multipurpose computer. Within a decade commercial uses of computers were introduces and it was largely due to the pioneering accomplishments of ENIAC. ENIAC may have never come if not (or at least not as quickly) if not hadn't been for WW War ll. The Navy needed faster ways to compute artilery firing charts. Theses charts took into account things like the wind elevation to make sure bombs hit the right targets. The people that they had doing the calculations simly could not do them fast enough. Even though John Mauchly already held a doctorate, he was at University of Pennsylvania hoping to learn how to create a device that would allow him to analyze meteorological data. His hope of studying electronics was cut short by the University. So many of the schools professors had been called away to do secret military research or on active duty that they hired him to teach physics. J. Presper Eckert was the top graduit student at the time. He already invented a device for measuring magnetic fields and recording sound on film. The Navy adopted Eckert's device to check the performance of their airborn mine sweeping operation.

Happy 50th Birthday, ENIAC! February 14th, 1996 ENIAC home page Unisys celebrates 50th birthday of ENIAC On February 14th 1946, at the Moore School of Electrical Engineering at the University of Pennsylvania, the late John W. Mauchly and J. Presper Eckert first demonstrated the ENIAC (Electronic Numerical Integrator and Computer). It was the first electronic general-purpose programmable computer. It had over 18,000 vacuum tubes (each of which was replaced, on the average, more than once a year), weighed over 30 tons, consumed nearly 200 KW of power, and occupied a room measuring 1500 square feet. It was capable of performing an addition or subtraction in 200 microseconds, and a multiplication in 2,800 microseconds (using 6 of the 20 accumulator s). ENIAC worked natively in decimal, where virtually all computers work in binary today. Each accumulator could store 10 decimal digits; signed decimal numbers were transmitted in parallel over 11 data lines. The clock speed was 100 KHz (3 orders of magnitude slower than the 486 computer I'm using now). When first built, the computer was programmed via patch panel, and was later modified to accept programs via punch card s. (To compare to modern computing hardware, look at

J. Presper Eckert, Jr. Als tweeëntwintigjarige pas afgestudeerde ingenieur kreeg hij de opdracht een cursus elektronica te geven in het ESMWT -programma. Eén van de "leerlingen" die de cursus volgde was John Mauchly Beide waren ze gefascineerd door elektronica en achtten het mogelijk een elektronische multifunctionele computer te bouwen. Op verzoek van Herman Goldstine deden ze het leger een voorstel en sleepten zo het ENIAC- contract in de wacht. Oneinigheid over het intellectuele eigendom van de "First Draft" zorgde voor een levenslange vijandigheid tegenover John von Neumann. Na discussie over het intellectuele eigendom van de ENIAC stichtten Eckert en Mauchly samen de The Eckert-Mauchly Corporation

E A B C D ... Z easter egg: A hidden suprise in a program or on a Web site. A special feature which is not otherwise made obvious but when "discovered" or clicked on offers something special. This could be in the form of an extra game level or secret area or an animation or a message of some kind. Programmers often "bury" easter eggs in their programs to add a certain extra depth to their program or Web site and to challenge users to find it. Eckert, John Presper: As a grad student studying at the Moore School in 1943, John Eckert met John Mauchly, who spoke about the idea of an electronic version of the Ganged Calculator. Mauchley needed someone to oversee the design and construction of the ENIAC computer, and it was J. Presper Eckert who rose to the challenge. They completed the first general purpose digital computer in 1946. Later that year, Eckert and Mauchly started a business partnership that become the Eckert-Mauchly Corp. Eckert died on June 3, 1995, from complications relating to leukemia. He was 76. e-journal: An electronic publication, similar to an e-zine or zine.

Prior to the live auction, bidders can compete for the piece of computing history online at skinner.lycos.com, and a trained Skinner professional will represent the winning bidder at the live auction as an absentee bidder. During World War II the U.S. Army faced an urgent need for ballistics formulae, and turned to the University of Pennsylvania’s School of Engineering to come up with a new calculating machine. Two individuals associated with the school, J. Presper Eckert and John Mauchly, had previously discussed using the relatively new science of electronics to improve the current mechanical and electro-mechanical calculating machines that were then state-of-the-art. The Army accepted their proposal and they began work in 1943. What they eventually built was ENIAC (Electronic Numerical Integrator And Computer), the first general purpose electronic digital computer.

Jeffery Winkler IBM and the first computers Charles Flint was a daredevil 19th Century capitalist who flew airplanes, and sold weapons to both sides in the Russo-Japanese War. In 1910, he merged three companies together. They were International Time Recording Company, which made clocks, The Computing Scale Company of America, which made scales, and the Hollerith Electric Tabulating System, which was the possession of an eccentric inventor named Herman Hollerith, who invented a tabulating machine for conducting the 1890 census. These tabulating machines used punchcards like computers would decades later. Charles Flint called his new company "Computing-Tabulating-Recording" or "CTR". Flint was more interested in increasing the price of CTR stock than creating a viable business entity. He was planning to simply sell out at a high price. In 1913, Flint chose as his chief executive officer Thomas Watson, who had been at NCR which made cash registers. Watson reorganized how business was conducted at CTR and plowed profits back into the company. The company greatly expanded during World War I. In February 1924, CTR was renamed "International Business Machines", or "IBM". IBM grew tremendously in the 1920's when society was becoming more urban and modernized. In the 1930's, it didn't do to badly because the New Deal created legions of bureaucrats, all of whom needed business machines. Watson stressed research and development, and discarded parts of the company that didn't fit into his plans. Just before World War II, it was the leading firm in it's field. The people at IBM thought in terms of inventing new commercially viable products with existing technology as opposed to creating new technology. The most technologically advanced thing they produced was the electric typewriter which had been invented at the turn of the century although IBM figured out a cost effective way of mass producing them. If their purpose was to make money, why would they be concerned with something on the edge of human ability that wouldn't be commercially viable in the foreseeable future? This began to change when Watson had contact with academia while selling them a scantron machine. Then electrical engineer J. Presper Eckert worked with IBM to develop a calculator. Harvard mathematician Howard Aiken wanted to build a machine that could retain a set of mathematical rules and apply them to new data later. He needed money to do it. He was aware of how Eckert had used IBM, and this inspired him to do the same thing. A deal was worked out where IBM and Harvard would work together to build a machine called Mark I. Work started on the project in 1940 with a $50,000 grant. It was finished in 1943. It was dismantled and shipped to Harvard for an official unveiling the following year. During the ceremony, Aiken acted like the machine was purely a Harvard creation and barely mentioned IBM at all. John Atanasoff, a physicist at Iowa State College, thought up a design for a fully electronic computer that would have much greater capacity and speed than Mark I. With the help of the army, John Mauchly and J. Presper Eckert built Atanasoff's machine. It was completed in 1946, and was called the Electronic Numerical Integrator and Computer, or ENIAC. Watson was offended at having been snubbed at the unveiling of Mark I. Primarily to regain lost pride, IBM worked with Eckert and others at Columbia to produce an new computer called SSEC. At this time several computers were being developed by a variety of universities and corporations in the U.S. and Britain. The government had encouraged them to work together for the war effort. IBM emerged from World War II much more powerful than when the war began. Sales and rentals had quadrupled. This was despite the fact that Watson was an old man who didn't understand or care about computers. However in 1949 Watson's son Watson Jr. came to power and recognized the potential of these behemoth machines. He produced the 701 which was more powerful than SSEC. At this time IBM was about two years behind Remington Band in the development of computers. In the early 1950's, Watson Jr. started the ambitious 700 series, and was committed to producing machines for commercial markets.

92. The First Stored Program Computer -- EDVAC During the course of designing ENIAC, it's creators, John William Mauchly andJ. presper eckert Jr., conceived the concept of stored program computing. http://www.maxmon.com/1946ad.htm

1944 AD to 1952 AD The First Stored Program Computer EDVAC As was previously discussed, If we ignore both Atanasoff's machine and COLOSSUS , then the first true general- purpose electronic computer was the ENIAC , which was constructed at the University of Pennsylvania between 1943 and 1946. However, ENIAC's underlying architecture was very different to that of modern computers. During the course of designing ENIAC, it's creators, John William Mauchly and J. Presper Eckert Jr. , conceived the concept of stored program computing. This concept was subsequently documented by Johann (John) von Neumann in his paper which is now known as the First Draft (The computer structure resulting from the criteria presented in the " First Draft " is popularly known as a von Neumann Machine, and virtually all digital computers from that time forward have been based on this architecture.) a In August 1944, Mauchly and Eckert proposed the building of a new machine called the electronic discrete variable automatic computer (EDVAC) . Unfortunately, although the conceptual design for EDVAC was completed by 1946, several key members left the project to pursue their own careers, and the machine did not become fully operational until 1952. When it was finally completed, EDVAC contained approximately 4,000 vacuum tubes and 10,000 crystal diodes. A 1956 report shows that EDVAC's average error-free up-time was approximately 8 hours.

Hacker Timeline: 19401969 1940s-1970s: Era of the mainframes (Catman). 1946: J. Presper Eckert and John W. Mauchly created one of the first digital, general-purpose computers: the Electronic Numerical Integrator and Computer (ENIAC) (Williams). 1949 J. Presper Eckert and John W. Mauchly created the first computer that stored its data on magnetic tape: the Binary Automatic Computer (BINAC) (Williams). 1950s: J. Presper Eckert and John W. Mauchly created the UNIVAC computer, which was the first computer that could handle alphanumeric information. It was also smaller than the previous computersthe first step to making computers smaller (Williams). Some of the first hackers of this time were Peter Deutsch, Bill Gosper, Richard Greenblatt, Tom Knight, and Jerry Sussman. (Brunvand). This was the "Golden Age" of hacking. This was when hackers made some of the largest and most important discoveries on computers. The hackers of this time are respected by the hackers of today because the computers they worked on were so cumbersome and they only had a few tools to help them learn about these machines (Brunvand). 1960s: Hacker culture spread to the general culture as the computers did. Centers of hacker culture had by now spread from MIT to Carnegie Mellon University, and Stanford University. Some of the famous hackers of this time were Ed Fredkin, Brian Reid, Jim Gosling, Brian Kernighan, Dennis Ritchie, and Richard Stallman (Brunvand).
