For example, the 1961 Semiconductor Network Computer (Molecular Electronic Computer, Mol-E-Com), [10] [11] [12] the first monolithic integrated circuit [13] [14] [15] general purpose computer (built for demonstration purposes, programmed to simulate a desk calculator) was built by Texas Instruments for the US Air Force.
The first solid-state electronic calculator was created in the early 1960s. ... on most 1970s and 1980s home computers. Calculator functions are ...
Friden Calculator Friden Flexowriter. In 1957, Friden purchased the Commercial Controls Corporation of Rochester, New York.This gave them the Flexowriter teleprinter, an electric typewriter capable of being used as part of unit record equipment developed in World War II for the Department of the Navy to automatically type "regret to inform you" letters to the survivors of fallen servicemen ...
The range was further extended by the inclusion of the Series J ten-key machines which provided a single finger calculation facility, and the Class 5 (later called Series C) key-driven calculators in both manual and electrical assisted comptometers. In the late 1960s, the Burroughs sponsored "nixi-tube" provided an electronic display calculator ...
The Curta was conceived by Curt Herzstark in the 1930s in Vienna, Austria.By 1938, he had filed a key patent, covering his complemented stepped drum. [3] [4] This single drum replaced the multiple drums, typically around 10 or so, of contemporary calculators, and it enabled not only addition, but subtraction through nines complement math, essentially subtracting by adding.
SEAC (Standards Eastern Automatic Computer) demonstrated at US NBS in Washington, DC – was the first fully functional stored-program computer in the U.S. May 1950: UK The Pilot ACE computer, with 800 vacuum tubes, and mercury delay lines for its main memory, became operational on 10 May 1950 at the National Physical Laboratory near London.
That was a common feature in the 1960s desktop computer/programmable calculator and only HP provided a true Von Neumann architecture which allowed for self-modifying code, [12] similarly to the contemporary general-purpose mainframes and minicomputers.
The 604 was also a component of the Test Assembly, a precursor to IBM's early computers. The circuit module design and packaging was also used for the IBM 650, the world's first mass-produced computer and a very popular computer during the 1960s. An all-transistor version of the 604 was built and demonstrated in October 1954. Although it used ...
