The ENIAC
The ENIAC was built by John Mauchly and J. Presper Eckert. It improved 1,000 times on the speed of it's others. The start of the project began in 1943. The ENIAC had 17,468 vacuum tubes, 70,000 resistors, 10,000 capacitors, 1,500 relays, and 6,000 manual switches. -
The IBM SSEC
IBM´s Selective Sequence Electronic Calculator produced "the moon-position tables used for plotting the course of the 1969 Apollo flight to the moon. It contained 20,000 relays and 12,500 vacuum tubes. It was 25 feet by 40 feet and the project was lead by Wallace Eckert. It did 50 multiplication per second. -
The Manchester Mark I
The project started in 1947 and ended in 1949. The Project was led by Frederick Williams and Tom Kilburn. It had 1300 vacuum tubes. -
The EDSAC
Maurice Wilkes assembled the EDSAC, or Electronic Delay Storage Automatic Calculator. The EDSAC was designed and built in England in Cambridge University. It was the world's first stored-program computer to operate a regular computing service. It did 714 operations per second. -
The Pilot ACE
The Pilot ACE was started in 1948, and completed in 1950 in the National Physical Laboratory in Britain. It had 800 vacuum tubes and took up 12 square feet. The project was lead by J. H. Wilkinson. -
The SEAC
The SEAC, or Standards Eastern Automatic Computer, was built by the National Bureau of Standards in Washington. It was the first computer to use all diode-logic and the first stored-program computer completed in the United states. -
The ERA 1101
Engineering Research Associates of Minneapolis built the ERA 1101, which was the first commercially produced computer. Their first costumer was the U.S Navy. It was introduced in 1950. -
The SWAC
The SWAC, or the Standards Western Automatic Computer, was completed by the National Bureau of Standards in the Institute for Numerical Analysis in Los Angeles. -
The UNIVAC I
The UNIVAC 1, or UNIVersal Automatic Computer was sold for more than $1 million dollars each. The project was lead by John Mauchly, and Presper Eckert. It took up 943 cubic feet. Their memory size was 1000 12-digit word. -
The MIT Whirlwind
The MIT Whirlwind was lead by Jay Forrester and Robert Everett. It takes up 3,100 square feet. It has 4,500 vacuum tubes, 14,800 diodes, and 2048 16-digit words. The project was started in 1945 and completed in 1951. -
The DEC PDP-1
Each computer costs $120,000. There was only 50 built, needed no air conditioning and only required one operator. Hackers at MIT wrote the first computerized video game for it, SpaceWar!. (programmed data processor-1) -
The Kenbak-1
The Kenbak-1 was the first personal computer that was advertised for $750 in Scientific American. It was designed by John Blankenbaker. It had a 256-byte memory, and in 1973, after only selling 40 machines, the Kenbak Corps. closed. -
The TV Typewriter
The TV Typewrite was designed by Don Lancaster. The information was displayed on a ordinary television set and the original design could store 512 characters as 16 lines of 32 characters. It had storage for about 100 pages of text. -
The Apple II
The Apple II was a big success with its printed circuit motherboard, switching power supply, switching power supply, keyboard, manual, and great color graphics. It was created by Steve Wozniak. It costs $1298 and had a 4K memory size. -
The Osborne 1
The Osborne I was completed by Adam Osborne. The Osborne I was the first portable computer, it cost $1795 and weighed 24 lbs. It's price was attractive to costumers because it had software worth about $1500. -
The Commodore 64
The Commodore 64 was introduced by Commodore International. It was sold for $595. It sold more than 22 million units before it was discontinued in 1993. It was also recognized by the Guinness Book of World Records as the greatest selling single computer model of all time in 2006. -
The Apple's Lisa
The Lisa was the first personal computer with a graphical user interface. It also costs $10,000. It ran on a Motorola 68000 microprocessor. It included a black and white monitor, mouse, windows and pop-up menus. -
The NeXT
The NeXT was unveiled by Steve Jobs. Its base price was $6500. It was the first personal computer to incorporate a drive for an optical storage disk, a built in signal processor that allowed voice recognition.
