Computer Research Corporation
The Computer Research Corporation (CRC) was an early developer of minicomputers. It was founded on July 16, 1950.Reilly 2003, p. 164. The founding owners of CRC were Floyd Steele, Donald Eckdahl, Hrant (Harold) Sarkinssian, Richard Sprague, and Irving S. Reed. With the exception of Reed, all members of the CRC had been on the design team for the MADDIDA, a special-purpose digital computer developed from 1946 to 1949 for Northrop.

Minicomputer
A minicomputer, or colloquially mini, is a class of smaller general purpose computers that developed in the mid-1960s and sold at a much lower price than mainframe and mid-size computers from IBM and its direct competitors. In a 1970 survey, ''The New York Times'' suggested a consensus definition of a minicomputer as a machine costing less than (), with an input-output device such as a teleprinter and at least four thousand words of memory, that is capable of running programs in a higher level language, such as Fortran or BASIC. The class formed a distinct group with its own software architectures and operating systems. Minis were designed for control, instrumentation, human interaction, and communication switching as distinct from calculation and record keeping. Many were sold indirectly to original equipment manufacturers (OEMs) for final end use application. During the two decade lifetime of the minicomputer class (1965–1985), almost 100 companies formed and only a hal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Floyd Steele
Floyd George Steele (June 28, 1918 – September 23, 1995) was an American physicist, engineer, and computer designer who grew up in Boulder, Colorado. He is known for leading the design team at Northrup that developed the MADIDDA, an early digital computer. Early life Floyd Steele grew up in Boulder, Colorado. He was named after his uncle, Floyd Odlum, a businessman known for coming out on top of the depression. Steele received his BA in physics from the University of Colorado, Boulder, a BS in electrical engineering and a MS in aeronautical engineering from Caltech. Before joining Northrop he worked for Douglas Aircraft from 1941 to 1944 and while in the Navy attended Captain Eddie's Radar School. MADDIDA Steele was the conceptual leader of the MADDIDA design group at Northrop Corporation.Reilly 2003, p. 164. Development of the MADDIDA began in 1946 with the goal of producing the first DIgital Data Analyzer (DIDA).Reilly 2003, p. 163. When the decision was made to ...

MADDIDA
The MADDIDA (Magnetic Drum Digital Differential Analyzer) was a special-purpose digital computer used for solving systems of ordinary differential equations. It was the first computer to represent bits using voltage levels and whose entire logic was specified in Boolean algebra. Invented by Floyd Steele, MADDIDA was developed at Northrop Aircraft Corporation between 1946 and 1949 to be used as a guidance system for the Snark missile. No guidance system, however, resulted from the work on the MADDIDA, and rather it was used for aeronautical research. In 1952, the MADDIDA became the world's top-selling commercial digital computer (albeit a special-purpose machine), six units having been sold. (The general-purpose UNIVAC I delivered its seventh unit in 1954.) Development Development on the project began in March 1946 at Northrop Corporation with the goal of producing a subsonic cruise missile designated "MX-775", which came to be called the Snark. Northrop's parameters fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northrop Corporation
Northrop Corporation was an American aircraft manufacturer from its formation in 1939 until its 1994 merger with Grumman to form Northrop Grumman. The company is known for its development of the flying wing design, most successfully the B-2 Spirit stealth bomber.Parker, Dana T. ''Building Victory: Aircraft Manufacturing in the Los Angeles Area in World War II,'' pp. 93-106, Cypress, CA, 2013. . History Jack Northrop founded 3 companies using his name. The first was the Avion Corporation in 1928, which was absorbed in 1929 by the United Aircraft and Transport Corporation as a subsidiary named "Northrop Aircraft Corporation" (and later became part of Boeing). The parent company moved its operations to Kansas in 1931, and so Jack, along with Donald Douglas, established a "Northrop Corporation" located in El Segundo, California, which produced several successful designs, including the Northrop Gamma and Northrop Delta. However, labor difficulties led to the dissolution of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Differential Analyzer
The differential analyser is a mechanical analogue computer designed to solve differential equations by integration, using wheel-and-disc mechanisms to perform the integration. It was one of the first advanced computing devices to be used operationally. The original machines could not add, but then it was noticed that if the two wheels of a rear differential are turned, the drive shaft will compute the average of the left and right wheels. A simple gear ratio of 1:2 then enables multiplication by two, Multiplication is just a special case of integration, namely integrating a constant function. History Research on solutions for differential equations using mechanical devices, discounting planimeters, started at least as early as 1836, when the French physicist Gaspard-Gustave Coriolis designed a mechanical device to integrate differential equations of the first order. The first description of a device which could integrate differential equations of any order was published in 18 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NCR Corporation
NCR Corporation, previously known as National Cash Register, is an American software, consulting and technology company providing several professional services and electronic products. It manufactures self-service kiosks, point-of-sale terminals, automated teller machines, cheque processing systems, and barcode scanners. NCR was founded in Dayton, Ohio, in 1884 and acquired by AT&T in 1991. A restructuring of AT&T in 1996 led to NCR's re-establishment on 1 January 1997, as a separate company and involved the spin-off of Lucent Technologies from AT&T. In June 2009 the company sold most of the Dayton properties and moved its headquarters to the Atlanta metropolitan area in unincorporated Gwinnett County, Georgia, near Duluth. In early January 2018, the new NCR Global Headquarters opened in Midtown Atlanta near Technology Square (adjacent to the Georgia Institute of Technology).

Computer Companies Established In 1950
A computer is a machine that can be programmed to carry out sequences of arithmetic or logical operations (computation) automatically. Modern digital electronic computers can perform generic sets of operations known as Computer program, programs. These programs enable computers to perform a wide range of tasks. A computer system is a nominally complete computer that includes the Computer hardware, hardware, operating system (main software), and peripheral equipment needed and used for full operation. This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of Programmable logic controller, industrial and Consumer electronics, consumer products use computers as control systems. Simple special-purpose devices like microwave ovens and remote controls are included, as are factory devices like industrial robots and computer-aided design, as well as general-purpose devices like personal compu ...
