Documation Inc
Documation was an American Stock Exchange-listed computer hardware manufacturer founded in 1969 in Melbourne, Florida that went public in 1976. They made (punched card) card readers used in some American elections 3 decades later. They also produced Impact Line printers. In late 1980, Storage Technology Corporation (STC) acquired Documation, which was subsequently spun off, and those companies which subdivided from it, most of which use Documation-like names, no longer manufacture computer peripherals. Documation was described as "a financially troubled printer manufacturer." IMPACT Line printers Documation's ''IMPACT 3000'', named for its 3,000 lines per minute rating, was followed a year later by the 3,800 LPM ''IMPACT 3800''. A 5,000 lines per minute printer was introduced in 1986, by which time the company was operating under the name StorageTek Printer Corp. Like earlier impact printer models, it is manufactured in Florida. At the time of the Series 5000's introducti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Stock Exchange
NYSE American, formerly known as the American Stock Exchange (AMEX), and more recently as NYSE MKT, is an American stock exchange situated in New York City. AMEX was previously a mutual organization, owned by its members. Until 1953, it was known as the New York Curb Exchange. NYSE Euronext acquired AMEX on October 1, 2008, with AMEX integrated with the Alternext European small-cap exchange and renamed the NYSE Alternext U.S. In March 2009, NYSE Alternext U.S. was changed to NYSE Amex Equities. On May 10, 2012, NYSE Amex Equities changed its name to NYSE MKT LLC. Following the SEC approval of competing stock exchange IEX in 2016, NYSE MKT rebranded as NYSE American and introduced a 350-microsecond delay in trading, referred to as a "speed bump", which is also present on the IEX. History The Curb market The exchange grew out of the loosely organized curb market of curbstone brokers on Broad Street in Manhattan. Efforts to organize and standardize the market started early in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ASCII
ASCII ( ), abbreviated from American Standard Code for Information Interchange, is a character encoding standard for electronic communication. ASCII codes represent text in computers, telecommunications equipment, and other devices. Because of technical limitations of computer systems at the time it was invented, ASCII has just 128 code points, of which only 95 are , which severely limited its scope. All modern computer systems instead use Unicode, which has millions of code points, but the first 128 of these are the same as the ASCII set. The Internet Assigned Numbers Authority (IANA) prefers the name US-ASCII for this character encoding. ASCII is one of the List of IEEE milestones, IEEE milestones. Overview ASCII was developed from telegraph code. Its first commercial use was as a seven-bit teleprinter code promoted by Bell data services. Work on the ASCII standard began in May 1961, with the first meeting of the American Standards Association's (ASA) (now the American Nat ...

IBM 2501
The IBM 2501 is a punched-card reader from IBM with models for the System/360 and System/370 mainframe systems and for the IBM System/360 Model 20, the IBM 1130 and IBM System/3 minicomputers. 2501 models can read 80-column cards at either 600 or 1000 cards per minute (CPM). The 2501 is no longer sold, but is simulated in software on current IBM systems. Models The 2501 comes in four models depending on speed and attachment features. Models for mainframe use come with an ''integrated control unit'' that performs the functions of a control unit required by other devices. The A1 and A2 are for the IBM 1130. Usage The 2501 uses a photoelectric sensor to read the data punched in the card. Cards are read ''serially'' (column by column) and the reader uses a simplified "straight through" card path. "Each column is read twice and the two readings are compared to check reading accuracy." In a mainframe environment the 2501 was frequently used for mainframe input in an "open shop" ...

Chad (paper)
Chad refers to fragments sometimes created when holes are made in a paper, card or similar synthetic materials, such as computer punched tape or punched cards. The word "chad" has been used both as a mass noun (as in "a pile of chad") and as a countable noun (pluralizing as in "many chads"). Etymology The origin of the term chad is uncertain. Patent documents from the 1930s and 1940s show the word "chad", often in reference to punched tape used in telegraphy. These patents sometimes include synonyms such as "chaff" and "chips". A patent filing in 1930 included a "receptacle or '' chad box'' ... to receive the chips cut from the edge of the tape." A 1938 patent filing included a "chaff or ''chad chute''" to collect the waste fragments. Both patents were assigned to Teletype Corporation. The plural ''chads'' is attested from about 1939, along with ''chadless'', meaning "without oosechad". Clear definitions for both terms are offered by Walter Bacon in a patent applicatio ...

2000 United States Presidential Election Recount In Florida
The 2000 United States presidential election recount in Florida was a period of vote recounting in Florida that occurred during the weeks after Election Day in the 2000 United States presidential election between George W. Bush and Al Gore. The Florida vote was ultimately settled in Bush's favor by a margin of 537 votes when the U.S. Supreme Court, in ''Bush v. Gore'', stopped a recount that had been initiated upon a ruling by the Florida Supreme Court. Bush's win in Florida gave him a majority of votes in the Electoral College and victory in the presidential election. Background The controversy began on election night, November 7, 2000, when the national television networks, using information provided to them by the Voter News Service, an organization formed by the Associated Press to help determine the outcome of the election through early result tallies and exit polling, first called Florida for Gore in the hour after polls closed in the peninsula (in the Eastern time ...

PDP-11
The PDP-11 is a series of 16-bit minicomputers sold by Digital Equipment Corporation (DEC) from 1970 into the 1990s, one of a set of products in the Programmed Data Processor (PDP) series. In total, around 600,000 PDP-11s of all models were sold, making it one of DEC's most successful product lines. The PDP-11 is considered by some experts to be the most popular minicomputer. The PDP-11 included a number of innovative features in its instruction set and additional general-purpose registers that made it much easier to program than earlier models in the PDP series. Further, the innovative Unibus system allowed external devices to be easily interfaced to the system using direct memory access, opening the system to a wide variety of peripherals. The PDP-11 replaced the PDP-8 in many real-time computing applications, although both product lines lived in parallel for more than 10 years. The ease of programming of the PDP-11 made it very popular for general-purpose computing uses also. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Equipment Corporation
Digital Equipment Corporation (DEC ), using the trademark Digital, was a major American company in the computer industry from the 1960s to the 1990s. The company was co-founded by Ken Olsen and Harlan Anderson in 1957. Olsen was president until forced to resign in 1992, after the company had gone into precipitous decline. The company produced many different product lines over its history. It is best known for the work in the minicomputer market starting in the mid-1960s. The company produced a series of machines known as the PDP line, with the PDP-8 and PDP-11 being among the most successful minis in history. Their success was only surpassed by another DEC product, the late-1970s VAX "supermini" systems that were designed to replace the PDP-11. Although a number of competitors had successfully competed with Digital through the 1970s, the VAX cemented the company's place as a leading vendor in the computer space. As microcomputers improved in the late 1980s, especially wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 half ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
