HP 250
The HP 250 was a multiuser business computer by Hewlett-Packard running HP 250 BASIC language as its OS with access to HP's IMAGE database management. It was produced by the General Systems Division (GSD), but was a major repackaging of desktop workstation HP 9835 which had been sold in small business configurations. The HP 9835's processor was initially used in the first HP 250s. The HP 250 borrowed the embedded keyboard design from the HP 300 and added a wider slide-able and tilt-able monitor with screen labeled function keys buttons physically placed just below on-screen labels (a configuration now used in ATMs and gas pumps) built into a large desk design. Though the HP 250 had a different processor and operating system, it used similar interface cards to the HP 300, and then later also the HP 3000 models 30, 33, 40, 42, 44, and 48: HP-IB channel (GIC), Network, and serial (MUX) cards. Usually the HP250 was a small HP-IB single channel system (limited to seven HP-IB dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

HP 3000
The HP 3000 series is a family of 16-bit and 32-bit minicomputers from Hewlett-Packard. It was designed to be the first minicomputer with full support for time-sharing in the hardware and the operating system, features that had mostly been limited to mainframes, or retrofitted to existing systems like Digital's PDP-11, on which Unix was implemented. First introduced in 1972, the last models reached end-of-life in 2010, making it among the longest-lived machines of its generation. The original HP 3000 hardware was withdrawn from the market in 1973 to address performance problems and OS stability. After reintroduction in 1974, it went on to become a reliable and powerful business system, one that regularly won HP business from companies using IBM's mainframes. Hewlett-Packard's initial naming referred to the computer as the System/3000, and then called it the HP 3000. The HP 3000 originally used a 16-bit CISC stack machine processor architecture, first implemented with Transis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

USASCII
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 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 National Standards Institut ...

Shift-out
Shift Out (SO) and Shift In (SI) are ASCII control characters 14 and 15, respectively (0x0E and 0x0F). These are sometimes also called "Control-N" and "Control-O". The original meaning of those characters provided a way to shift a coloured ribbon, split longitudinally usually with red and black, up and down to the other colour in an electro-mechanical typewriter or teleprinter, such as the Teletype Model 38, to automate the same function of manual typewriters. Black was the conventional ambient default colour and so was shifted "in" or "out" with the other colour on the ribbon. Later advancements in technology instigated use of this function for switching to a different font or character set and back. This was used, for instance, in the Russian character set known as KOI7-switched, where SO starts printing Russian letters, and SI starts printing Latin letters again. Similarly, they are used for switching between Katakana and Roman letters in the 7-bit version of the Japanese JIS ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

HP Roman Extension Set
In computing HP Roman is a family of character sets consisting of HP Roman Extension, HP Roman-8, HP Roman-9 and several variants. Originally introduced by Hewlett-Packard around 1978, revisions and adaptations were published several times up to 1999. The 1985 revisions were later standardized as IBM codepages 1050 and 1051. Supporting many European languages, the character sets were used by various HP workstations, terminals, calculators as well as many printers, also from third-parties. Overview HP Roman is a family of single byte character encodings supporting several Latin script based languages of Europe. It was originally introduced by Hewlett-Packard around 1978 as 7- and 8-bit HP Roman Extension for some of their computer terminals and printers. Early versions of the 8-bit variant were also used by some HP workstations in 1978/1979. Several revisions led to more characters being added before the 8-bit variant of the character set became officially known as HP Roman-8 ...

Gasoline Pump
A gasoline pump is a machine at a filling station that is used to pump gasoline (petrol), diesel, or other types of liquid fuel into vehicles. Gasoline pumps are also known as bowsers or petrol bowsers (in Australia), petrol pumps (in Commonwealth countries), or gas pumps (in North America). History The first gasoline pump was invented and sold by Sylvanus Bowser in Fort Wayne, Indiana on September 5, 1885, pre-dating the automobile industry- It was commonly used to dispense the kerosene used in lamps and stoves. He later improved upon the pump by adding safety measures, and by adding a hose to directly dispense fuel into automobiles. For a while, the term ''bowser'' was used to refer to a vertical gasoline pump. In the United States this term is now only used for trucks that carry and dispense fuel to large aircraft at airports, but it is still used sometimes in Australia and New Zealand. The first gasoline pump was patented by Norwegian John J. Tokheim in 1901. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automated Teller Machine
An automated teller machine (ATM) or cash machine (in British English) is an electronic telecommunications device that enables customers of financial institutions to perform financial transactions, such as cash withdrawals, deposits, funds transfers, balance inquiries or account information inquiries, at any time and without the need for direct interaction with bank staff. ATMs are known by a variety of names, including automatic teller machine (ATM) in the United States (sometimes redundantly as "ATM machine"). In Canada, the term ''automated banking machine'' (ABM) is also used, although ATM is also very commonly used in Canada, with many Canadian organizations using ATM over ABM. In British English, the terms ''cashpoint'', ''cash machine'' and ''hole in the wall'' are most widely used. Other terms include ''any time money'', ''cashline'', ''tyme machine'', ''cash dispenser'', ''cash corner'', ''bankomat'', or ''bancomat''. ATMs that are not operated by a financial i ...

Screen Labeled Function Keys
A soft key is a button flexibly programmable to invoke any of a number of functions rather than being associated with a single fixed function or a fixed set of functions. A softkey often takes the form of a screen-labeled function key located alongside a display device, where the button invokes a function described by the text at that moment shown adjacent to the button on the display. Soft keys are also found away from the display device, for example on the sides of cellular phones, where they are typically programmed to invoke functions such as PTT, memo, or volume control. Function keys on keyboards are a form of soft key. In contrast, a hard key is a key with dedicated function such as the keys on a number keypad. Screen-labeled function keys are today most commonly found in kiosk applications, such as automated teller machines and gas pumps. Screen-label function keys date to aviation applications in the late 1960s. Kiosk applications were particularly common in the 1990s ...
