IBM 604 Electronic Calculator at NEMO national science museum in Amsterdam. Note plugboard control panel used to program the 604, at bottom.. The IBM 604 Electronic Calculating Punch was the world's first mass-produced electronic calculator along with its predecessor the IBM 603. [1]
The Fuller calculator, sometimes called Fuller's cylindrical slide rule, is a cylindrical slide rule with a helical main scale taking 50 turns around the cylinder. This creates an instrument of considerable precision – it is equivalent to a traditional slide rule 25.40 metres (1,000 inches) long.
The tube technology of the ANITA was superseded in June 1963 by the U.S. manufactured Friden EC-130, which had an all-transistor design, a stack of four 13-digit numbers displayed on a 5-inch (13 cm) cathode-ray tube (CRT), and introduced Reverse Polish Notation (RPN) to the calculator market for a price of $2200, which was about three times ...
(Reuters) -Summit Materials said on Monday rival Quikrete would acquire the company in a deal valued at $11.5 billion, in a move to capitalize on higher demand for building materials. The company ...
The IBM 603 was adapted as the arithmetic unit in the IBM Selective Sequence Electronic Calculator. It was designed by James W. Bryce, [2] and included circuits patented by A. Halsey Dickenson in 1937. [3] The IBM 603 was developed in Endicott, New York, and announced on September 27, 1946. [4] Full size and miniature vacuum tubes
The IBM 608 Transistor Calculator, a plugboard-programmable unit, was the first IBM product to use transistor circuits without any vacuum tubes and is believed to be the world's first all-transistorized calculator to be manufactured for the commercial market. [1] [2]: 34 Announced in April 1955, [3] [4] it was released in December 1957. The 608 ...
The ENIAC computer (1946) had over 17,000 tubes and suffered a tube failure (which would take 15 minutes to locate) on average every two days. In operation the ENIAC consumed 150 kilowatts of power, [ 3 ] of which 80 kilowatts were used for heating tubes, 45 kilowatts for DC power supplies, 20 kilowatts for ventilation blowers, and 5 kilowatts ...
Hydroforming uses liquid under extreme pressures to form metal tubes. It was developed for the plumbing industry and by 1990 achieved production efficiencies suited for high volume autos. Typically hydroforming is done at ambient temperatures, and limits the forming elongation of metals to 8–12% diameter increase for aluminum , and 25–40% ...
