Transistori tööpõhimõte    

1949 Maurice Wilkes assembled the EDSAC, the first practical stored-program computer, at Cambridge University. His ideas grew out of the Moore School lectures he had attended three years earlier. For programming the EDSAC, Wilkes established a library of short programs called subroutines stored on punched paper tapes.   TECHNOLOGY: vacuum tubes MEMORY: 1K words, 17 bits, mercury delay line SPEED: 714 operations per second

1950       Engineering Research Associates of Minneapolis built the ERA 1101, the first commercially produced computer; the company's first customer was the U.S. Navy. It held 1 million bits on its magnetic drum, the earliest magnetic storage devices. Drums registered information as magnetic pulses in tracks around a metal cylinder. Read/write heads both recorded and recovered the data. Drums eventually stored as many as 4,000 words and retrieved any one of them in as little as five-thousandths of a second.

1951       The UNIVAC I delivered to the U.S. Census Bureau was the first commercial computer to attract widespread public attention. Although manufactured by Remington Rand, the machine often was mistakenly referred to as the "IBM UNIVAC." Remington Rand eventually sold 46 machines at more than $1 million each. SPEED: 1,905 operations per second INPUT/OUTPUT: magnetic tape, unityper, printer MEMORY SIZE: 1,000 12-digit words in delay lines MEMORY TYPE: delay lines, magnetic tape TECHNOLOGY: serial vacuum tubes, delay lines, magnetic tape FLOOR SPACE: 943 cubic feet COST: F.O.B. factory $750,000 plus

Early AI programs: checkers, chess (Britain)‏ Strachey wrote a checkers program for the Ferranti Mark I at Manchester (with Turing's encouragement and utilising the latter's recently completed Programmers' Handbook for the Ferranti computer). By the summer of 1952 this program could, Strachey reported, "play a complete game of Draughts at a reasonable speed". Prinz's chess program, also written for the Ferranti Mark I, first ran in November 1951. It was for solving simple problems of the mate-in-two variety. The program would examine every possible move until a solution was found. On average several thousand moves had to be examined in the course of solving a problem, and the program was considerably slower than a human player. Turing started to program his Turochamp chess-player on the Ferranti Mark I but never completed the task. Unlike Prinz's program, the Turochamp could play a complete game and operated not by exhaustive search but under the guidance of rule-of-thumb principles devised by Turing.

Early AI programs: checkers (USA)‏ The first AI program to run in the U.S. was also a checkers program, written in 1952 by Arthur Samuel of IBM for the IBM 701. Samuel took over the essentials of Strachey's program (which Strachey had publicised at a computing conference in Canada in 1952) and over a period of years considerably extended it. In 1955 he added features that enabled the program to learn from experience, and therefore improve its play. Samuel included mechanisms for both rote learning and generalisation. The program soon learned enough to outplay its creator. Successive enhancements that Samuel made to the learning apparatus eventually led to the program winning a game against a former Connecticut checkers champion in 1962 (who immediately turned the tables and beat the program in six games straight).

1952 Heinz Nixdorf founded Nixdorf Computer Corp. in Germany. It remained an independent corporation until merging with Siemens in 1990. A complaint is filed against IBM, alleging monopolistic practices in its computer business, in violation of the Sherman Act. G. W. Dummer, a radar expert from Britain's Royal Radar Establishment presents a paper proposing that a solid block of materials be used to connect electronic components, with no connecting wires.

1953     IBM shipped its first electronic computer, the 701. Speedcoding: John Backus.

1954 Texas Instruments announces the start of commercial production on silicon transistors. [110]   Herbert Simon and Allen Newell unveiled Logic Theorist software that supplied rules of reasoning and proved symbolic logic theorems. The Logic Theorist, as the program became known, was the major exhibit at a conference organised in 1956 at Dartmouth College, New Hampshire, by John McCarthy, who subsequently became one of the most influential figures in AI. Newell, Simon and Shaw went on to construct the General Problem Solver, or GPS. The first version of GPS ran in 1957 and work continued on the project for about a decade. GPS could solve an impressive variety of puzzles, for example the "missionaries and cannibals" problem.

1955 William Shockley founds Shockley Semiconductor in Palo Alto, California However, the venture did not go well, partly because of Shockley's managerial style, and partly because he diverted resources away from transistor technology and into the creation of a 4-layer switching diode, a device which he had conceived whilst still at Bell.

1956 A U.S. District Court makes a final judgement on the complaint against IBM filed in January 1952 regarding monopolistic practices. A "consent decree" is signed by IBM, placing limitations on how IBM conducts business with respect to "electronic data processing machines". IBM develops the first hard disk, the RAMAC 305, with 50 two-foot diameter platters. Total capacity is 5 MB. (350 Disk Storage Unit)‏ The first transistorized computer is completed, the TX-O (Transistorized Experimental computer), at the Massachusetts Institute of Technology. The Nobel Prize in physics is awarded to John Bardeen, Walter Brattain, and William Shockley for their work on the transistor.

1959 Fairchild Semiconductor files a patent application for the planar process for manufacturing transistors. The process makes commercial production of transistors possible and leads to Fairchild's introduction, in two years, of the first integrated circuit. Texas Instruments announces the discovery of the integrated circuit. At Fairchild Semiconductor, Robert Noyce constructs an integrated circuit with components connected by aluminum lines on a silicon-oxide surface layer on a plane of silicon. Fairchild Semiconductor announces their independent discovery of the integrated circuit.

John Kemeny and Thomas Kurtz develop the BASIC programming language at Dartmouth College. BASIC is an acronym for Beginners All-purpose Symbolic Instruction Code. Texas Instruments receives a patent on the integrated circuit.

1965 Digital Equipment Corp (abbreviated DEC) introduced the PDP-8, the first commercially successful minicomputer. The PDP-8 sold for $18,000, one-fifth the price of a small IBM 360 mainframe. The speed, small size, and reasonable cost enabled the PDP-8 to go into thousands of manufacturing plants, small businesses, and scientific laboratories.

1966 Steven Gray founds the Amateur Computer Society, and begins publishing the ACS Newsletter. Some consider this to be the birth-date of personal computing. International Research Corp. is incorporated by Wayne Pickette as a one man, California corporation. Purpose, to research educational resources and technological improvements for education

1967… The first Consumer Electronics Show is held in New York City. International Research applies for a patent for a method of constructing double sided magnetic tape utilizing a MU-Metal Foil Inter layer.

Ed Roberts and Forest Mims found Micro Instrumentation Telemetry Systems (MITS). IBM scientist John Cocke and others complete a prototype scientific computer called the ACS. It incorporates some RISC concepts, but the project is later canceled due to the instruction set not being compatible with that of IBM's System/360 computers.

…1968 Douglas C. Engelbart, of the Stanford Research Institute, demonstrates his system of keyboard, keypad, mouse, and windows at the Joint Computer Conference in San Francisco's Civic Center.
