Spanish Peseta
The peseta (, ), * ca, pesseta, was the currency of Spain between 1868 and 2002. Along with the French franc, it was also a ''de facto'' currency used in Andorra (which had no national currency with legal tender). Etymology The name of the currency originally comes from ''peceta'', a Catalan diminutive form of the (Catalan) word ''peça'' (lit. ''piece'', i.e. a coin), not from the Spanish ''peso'' (lit. ''weight''). The word ''peseta'' has been known as early as 1737 to colloquially refer to the coin worth 2 ''reales provincial'' or of a peso. Coins denominated in "pesetas" were briefly issued in 1808 in Barcelona under French occupation; see Catalan peseta. Symbol Traditionally, there was never a single symbol or special character for the Spanish peseta. Common abbreviations were "Pta" (plural: "Pts), "Pt", and "Ptas". A common way of representing amounts of pesetas in print was using superior letters: "Pta" and "Pts". Common Spanish models of mechanical typewrit ...

Spanish Guinea
Spanish Guinea (Spanish: ''Guinea Española'') was a set of insular and continental territories controlled by Spain from 1778 in the Gulf of Guinea and on the Bight of Bonny, in Central Africa. It gained independence in 1968 as Equatorial Guinea. History 18th—19th centuries The Spanish colony in the Guinea region was established in 1778, by the Treaty of El Pardo between the Spanish Empire and the Portuguese Empire. Between 1778 and 1810, Spain administered the territory of Equatorial Guinea via its colonial Viceroyalty of the Río de la Plata, based in Buenos Aires (in present-day Argentina). From 1827 to 1843, the United Kingdom had a base on Bioko to combat the continuing Atlantic slave trade conducted by Spain and illegal traders. Based on an agreement with Spain in 1843, Britain moved its base to its own colony of Sierra Leone in West Africa. In 1844, on restoration of Spanish sovereignty, it became known as the "''Territorios Españoles del Golfo de Guinea''". ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peso
The peso is the monetary unit of several countries in the Americas, and the Philippines. Originating in the Spanish Empire, the word translates to "weight". In most countries the peso uses the Dollar sign, same sign, "$", as many currencies named "dollar". The sign "Philippine peso sign, ₱" is used in the Philippines. The silver ''peso'' worth eight ''Spanish real, reales'' was also known in English as a Spanish dollar or "piece of eight" and was a widely used international trade coin from the 16th to the 19th century. Origin and history 1537–1686 piece of eight The name peso was given to the 8-Spanish real, real silver coin introduced in 1497, minted at 8 pesos to a Castilian mark (230.0465 grams) of silver 134/144 fine (25.56 g fine silver). It was minted in large quantities after the discovery of silver in Mexico, Peru and Bolivia in the 16th century, and immediately became a coin of worldwide importance in international trade between Europe, Asia and North America. ...

Spreadsheet
A spreadsheet is a computer application for computation, organization, analysis and storage of data in tabular form. Spreadsheets were developed as computerized analogs of paper accounting worksheets. The program operates on data entered in cells of a table. Each cell may contain either numeric or text data, or the results of formulas that automatically calculate and display a value based on the contents of other cells. The term ''spreadsheet'' may also refer to one such electronic document. Spreadsheet users can adjust any stored value and observe the effects on calculated values. This makes the spreadsheet useful for "what-if" analysis since many cases can be rapidly investigated without manual recalculation. Modern spreadsheet software can have multiple interacting sheets and can display data either as text and numerals or in graphical form. Besides performing basic arithmetic and mathematical functions, modern spreadsheets provide built-in functions for common financial a ...

Code Page 437
Code page 437 (CCSID 437) is the character set of the original IBM PC (personal computer). It is also known as CP437, OEM-US, OEM 437, PC-8, or DOS Latin US. The set includes all printable ASCII characters as well as some accented letters (diacritics), Greek letters, icons, and line-drawing symbols. It is sometimes referred to as the "OEM font" or "high ASCII", or as "extended ASCII" (one of many mutually incompatible ASCII extensions). This character set remains the primary set in the core of any EGA and VGA-compatible graphics card. As such, text shown when a PC reboots, before fonts can be loaded and rendered, is typically rendered using this character set. Many file formats developed at the time of the IBM PC are based on code page 437 as well. Display adapters The original IBM PC contained this font as a 9×14 pixels-per-character font stored in the ROM of the IBM Monochrome Display Adapter (MDA) and an 8×8 pixels-per-character font of the Color Graphics Adapter ( CGA) ca ...

MS-DOS
MS-DOS ( ; acronym for Microsoft Disk Operating System, also known as Microsoft DOS) is an operating system for x86-based personal computers mostly developed by Microsoft. Collectively, MS-DOS, its rebranding as IBM PC DOS, and a few operating systems attempting to be compatible with MS-DOS, are sometimes referred to as "DOS" (which is also the generic acronym for disk operating system). MS-DOS was the main operating system for IBM PC compatibles during the 1980s, from which point it was gradually superseded by operating systems offering a graphical user interface (GUI), in various generations of the graphical Microsoft Windows operating system. IBM licensed and re-released it in 1981 as PC DOS 1.0 for use in its PCs. Although MS-DOS and PC DOS were initially developed in parallel by Microsoft and IBM, the two products diverged after twelve years, in 1993, with recognizable differences in compatibility, syntax, and capabilities.

Color Graphics Adapter
The Color Graphics Adapter (CGA), originally also called the ''Color/Graphics Adapter'' or ''IBM Color/Graphics Monitor Adapter'', introduced in 1981, was IBM's first color graphics card for the IBM PC and established a de facto computer display standard. Hardware design The original IBM CGA graphics card was built around the Motorola 6845 display controller, came with 16 kilobytes of video memory built in, and featured several graphics and text modes. The highest display resolution of any mode was 640×200, and the highest color depth supported was 4-bit (16 colors). The CGA card could be connected either to a direct-drive CRT monitor using a 4-bit digital (TTL) RGBI interface, such as the IBM 5153 color display, or to an NTSC-compatible television or composite video monitor via an RCA connector. The RCA connector provided only baseband video, so to connect the CGA card to a television set without a composite video input required a separate RF modulator. IBM pr ...

IBM Monochrome Display Adapter
The Monochrome Display Adapter (MDA, also MDA card, Monochrome Display and Printer Adapter, MDPA) is IBM's standard video display card and computer display standard for the IBM PC introduced in 1981. The MDA does not have any pixel-addressable graphics modes, only a single monochrome text mode which can display 80 columns by 25 lines of high resolution text characters or symbols useful for drawing forms. Hardware design The original IBM MDA was an 8-bit ISA card with a Motorola 6845 display controller, 4 KB of RAM, a DE-9 output port intended for use with an IBM monochrome monitor, and a parallel port for attachment of a printer, avoiding the need to purchase a separate card. Capabilities The MDA was based on the IBM System/23 Datamaster's display system, and was intended to support business and word processing use with its sharp, high-resolution characters. Each character is rendered in a box of 9×14 pixels, of which 7×11 depicts the character itself and the othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Read-only Memory
Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM cannot be electronically modified after the manufacture of the memory device. Read-only memory is useful for storing software that is rarely changed during the life of the system, also known as firmware. Software applications (like video games) for programmable devices can be distributed as plug-in cartridges containing ROM. Strictly speaking, ''read-only memory'' refers to memory that is hard-wired, such as diode matrix or a mask ROM integrated circuit (IC), which cannot be electronically changed after manufacture. Although discrete circuits can be altered in principle, through the addition of bodge wires and/or the removal or replacement of components, ICs cannot. Correction of errors, or updates to the software, require new devices to be manufactured and to replace the installed device. Floating-gate ROM semiconductor memory in the form of erasab ...

IBM PC
The IBM Personal Computer (model 5150, commonly known as the IBM PC) is the first microcomputer released in the IBM PC model line and the basis for the IBM PC compatible de facto standard. Released on August 12, 1981, it was created by a team of engineers and designers directed by Don Estridge in Boca Raton, Florida. The machine was based on open architecture and third-party peripherals. Over time, expansion cards and software technology increased to support it. The PC had a substantial influence on the personal computer market. The specifications of the IBM PC became one of the most popular computer design standards in the world. The only significant competition it faced from a non-compatible platform throughout the 1980s was from the Apple Macintosh product line. The majority of modern personal computers are distant descendants of the IBM PC. History Prior to the 1980s, IBM had largely been known as a provider of business computer systems. As the 1980s opened, their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM Electric Typewriter
The IBM Electric typewriters were a series of electric typewriters that IBM manufactured, starting in the mid-1930s. They used the conventional moving carriage and typebar mechanism, as opposed to the fixed carriage and type ball used in the IBM Selectric, introduced in 1961. After 1944, each model came in both "Standard" and "Executive" versions, the latter featuring proportional spacing. History The IBM Electromatic typewriter was the first electric typewriter to enjoy long-term commercial success. Unlike the later IBM Selectric typewriter, this typewriter model used a conventional moving carriage and typebar mechanism. The history of the Electromatic goes back to 1924, when the North East Electric Company received patent rights for the power roller from James Smathers. At that time, the company was selling electric motors, and wanted to get into the typewriter business. They reached an arrangement with Remington, securing a contract for 2,500 machines in 1925. N.

Typewriter
A typewriter is a mechanical or electromechanical machine for typing characters. Typically, a typewriter has an array of keys, and each one causes a different single character to be produced on paper by striking an inked ribbon selectively against the paper with a type element. At the end of the nineteenth century, the term 'typewriter' was also applied to a ''person'' who used such a device. The first commercial typewriters were introduced in 1874, but did not become common in offices until after the mid-1880s. The typewriter quickly became an indispensable tool for practically all writing other than personal handwritten correspondence. It was widely used by professional writers, in offices, business correspondence in private homes, and by students preparing written assignments. Typewriters were a standard fixture in most offices up to the 1980s. Thereafter, they began to be largely supplanted by personal computers running word processing software. Nevertheless, typewr ...

AEG Olympia - Traveller De Luxe - Spanish Keyboard Layout-9620
Allgemeine Elektricitäts-Gesellschaft AG (AEG; ) was a German producer of electrical equipment founded in Berlin as the ''Deutsche Edison-Gesellschaft für angewandte Elektricität'' in 1883 by Emil Rathenau. During the Second World War, AEG worked with the Nazi Party and benefited from forced labour from concentration camps. After World War II, its headquarters moved to Frankfurt am Main. In 1967, AEG joined with its subsidiary Telefunken AG, creating ''Allgemeine Elektricitäts-Gesellschaft AEG-Telefunken''. In 1985, Daimler-Benz purchased the ''AEG-Telefunken Aktiengesellschaft'' (which was renamed to ''AEG Aktiengesellschaft'') and wholly integrated the company in 1996 into Daimler-Benz AG (1998: DaimlerChrysler). The remains of AEG became part of Adtranz (later Bombardier Transportation) and Deutsche Aerospace (1998: DASA, today part of Airbus SE). After acquiring the AEG household subsidiary AEG Hausgeräte GmbH in 1994, Electrolux obtained the rights to the AEG brand ...
