ElectroData Corporation
Sibyl Rock at the console of an ElectroData Datatron computer in 1955 The ElectroData Corporation is a defunct computer company located in Pasadena, California. ElectroData originated as a part of Consolidated Electrodynamics Corporation (CEC), which manufactured scientific equipment. Clifford Berry and Sibyl M. Rock developed an analog computer to process the output of CEC's mass spectrometer. Berry then urged CEC to develop a digital computer as a follow-on. In 1951 CEC enlisted Harry Huskey, who managed the development of the SWAC computer on the project. In May 1952, CEC pre-announced the "CEC 30-201" computer, a vacuum tube computer with a magnetic-drum memory. That same year CEC reorganized computer development into a separate Computer Division. In 1954 the division was spun off into a separate public company named ElectroData. In 1954 the first model of the computer, now named the Datatron 203 shipped to the Jet Propulsion Laboratory in Pasadena. The purchase pric ...

Sibyl Rock Control Engineering 1955
The sibyls (, singular ) were prophetesses or oracles in Ancient Greece. The sibyls prophesied at holy sites. A sibyl at Delphi has been dated to as early as the eleventh century BC by PausaniasPausanias 10.12.1 when he described local traditions in his writings from the second century AD. At first, there appears to have been only a single sibyl. By the fourth century BC, there appear to have been at least three more, Phrygian, Erythraean, and Hellespontine. By the first century BC, there were at least ten sibyls, located in Greece, Italy, the Levant, and Asia Minor. History The English word ''sibyl'' ( or ) is from Middle English, via the Old French and the Latin from the ancient Greek (). Varro derived the name from an Aeolic ''sioboulla'', the equivalent of Attic '' theobule'' ("divine counsel"). This etymology is still widely accepted, although there have been alternative proposals in nineteenth-century philology suggesting Old Italic or Semitic derivation. The f ...

Datatron
The Datatron is a family of decimal vacuum tube computers developed by ElectroData Corporation and first shipped in 1954. The Datatron was later marketed by Burroughs Corporation after Burroughs acquired ElectroData in 1956. The Burroughs models of this machine were still in use into the 1960s. History Consolidated Electrodynamics Corporation (CEC), ElectroData's parent corporation, first pre-announced the Datatron in 1952 as the "CEC 30-201". Known also as CEC 30-203 (ElectroData 203), ElectroData 204 or 205, Burroughs 205 (different names signify the development and addition of new peripherals). The first systems were equipped with an "Electrodata 203" processor and were shipped to the Jet Propulsion Laboratory (JPL) and the National Bureau of Standards (NBS) in 1954. That same year design began on the "30-240" processor, enhanced to support magnetic tape. The name "Datatron" was first used in 1955. Description The Datatron has a word size of ten decimal digits plus a sign. C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Companies Established In 1954
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 programs. These programs enable computers to perform a wide range of tasks. A computer system is a nominally complete computer that includes the 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 industrial and 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 computers and mobile devices like smartphones. Computers power the Internet, which li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stock Swap
In corporate finance a stock swap is the exchange of one equity-based asset for another, where, during the merger or acquisition, the swap provides an opportunity to pay with stock rather than with cash; see . Overview The acquiring company essentially uses its own stock as cash to purchase the business. Each shareholder of the acquired company will receive a pre-determined number of shares from the acquiring company. Before the swap occurs each party must accurately value their company so that a fair " swap ratio" can be calculated. The valuation of a company is complicated in general; here though, additional to fair market value, the investment- and intrinsic value are to be determined as well. After the valuation is complete, the parties will agree upon the swap ratio; this will determine the number of shares that each shareholder will receive. In theory, a fair ratio is such that shareholders in both previous companies now own a pro-rated share of the new company: ...

Burroughs Corporation
The Burroughs Corporation was a major American manufacturer of business equipment. The company was founded in 1886 as the American Arithmometer Company. In 1986, it merged with Sperry UNIVAC to form Unisys. The company's history paralleled many of the major developments in computing. At its start, it produced mechanical adding machines, and later moved into programmable ledgers and then computers. It was one of the largest producers of mainframe computers in the world, also producing related equipment including typewriters and printers. Early history In 1886, the American Arithmometer Company was established in St. Louis, Missouri, to produce and sell an adding machine invented by William Seward Burroughs (grandfather of Beat Generation author William S. Burroughs). In 1904, six years after Burroughs' death, the company moved to Detroit and changed its name to the Burroughs Adding Machine Company. It was soon the biggest adding machine company in America. Evolving product ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jet Propulsion Laboratory
The Jet Propulsion Laboratory (JPL) is a federally funded research and development center and NASA field center in the City of La Cañada Flintridge, California, United States. Founded in the 1930s by Caltech researchers, JPL is owned by NASA and managed by the nearby California Institute of Technology (Caltech). The laboratory's primary function is the construction and operation of planetary robotic spacecraft, though it also conducts Earth-orbit and astronomy missions. It is also responsible for operating the NASA Deep Space Network. Among the laboratory's major active projects are the Mars 2020 mission, which includes the ''Perseverance'' rover and the '' Ingenuity'' Mars helicopter; the Mars Science Laboratory mission, including the ''Curiosity'' rover; the InSight lander (''Interior Exploration using Seismic Investigations, Geodesy and Heat Transport''); the ''Mars Reconnaissance Orbiter''; the ''Juno'' spacecraft orbiting Jupiter; the ''SMAP'' satellite for earth surface s ...

Corporate Spin-off
A corporate spin-off, also known as a spin-out, or starburst or hive-off, is a type of corporate action where a company "splits off" a section as a separate business or creates a second incarnation, even if the first is still active. Characteristics Spin-offs are divisions of companies or organizations that then become independent businesses with assets, employees, intellectual property, technology, or existing products that are taken from the parent company. Shareholders of the parent company receive equivalent shares in the new company in order to compensate for the loss of equity in the original stocks. However, shareholders may then buy and sell stocks from either company independently; this potentially makes investment in the companies more attractive, as potential share purchasers can invest narrowly in the portion of the business they think will have the most growth. In contrast, divestment can also sever one business from another, but the assets are sold off rather t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
