Philips VG5000
The VG5000μ is a computer created by Philips in 1984. It was manufactured in Le Mans by Radiotechnique (RTS) and marketed under the Philips, Radiotechnique, Radiola and Schneider Rundfunkwerke, Schneider brands. Not compatible with any other machines, it offered VG5000 BASIC (derived from Microsoft BASIC-80) as the operating system upon boot. Graphic ability was limited to a semigraphic symbol display, with the equivalent resolution of 320 x 250 in 8 colors. There are about forty games available for the system. 300 000 units were sold in 1984, according to an internal Philips report, with 500 000 predicted for 1985. Aimed at schools, it was unsuccessful and production ended in 1986. As of 2022, enthusiasts remain active in developing new Homebrew (video games), homebrew software and Emulator, emulators for the system. Specifications * Zilog Z80, Zilog Z80A processor running at 4 MHz * RAM: 24KB, including 16KB of system memory (expandable to 48KB) and 8KB of dedicated ...

Microsoft BASIC
Microsoft BASIC is the foundation software product of the Microsoft company and evolved into a line of BASIC interpreters and compiler(s) adapted for many different microcomputers. It first appeared in 1975 as Altair BASIC, which was the first version of BASIC published by Microsoft as well as the first high-level programming language available for the Altair 8800 microcomputer. During the home computer craze during the late-1970s and early-1980s, BASIC was ported to and supplied with many home computer designs. Slight variations to add support for machine-specific functions, especially graphics, led to a profusion of related designs like Commodore BASIC and Atari Microsoft BASIC. As the early home computers gave way to newer designs like the IBM Personal Computer and Macintosh, Apple Macintosh, BASIC was no longer as widely used, although it retained a strong following. The release of Visual Basic (classic), Visual Basic reboosted its popularity and it remains in wide use on Mic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SCART
SCART (also known as or , especially in France, 21-pin EuroSCART in marketing by Sharp in Asia, Euroconector in Spain, EuroAV or EXT, or EIA Multiport in the United States, as an EIA interface) is a French-originated standard and associated 21-pin connector for connecting audio-visual (AV) equipment. The name SCART comes from , "Radio and Television Receiver Manufacturers' Association", the French organisation that created the connector in the mid-1970s. The related European standard EN 50049 has then been refined and published in 1978 by CENELEC, calling it ''péritelevision'', but it is commonly called by the abbreviation ''péritel'' in French. The signals carried by SCART include both composite and RGB (with composite synchronisation) video, stereo audio input/output and digital signalling. The standard was extended at the end of the 1980s to support the new S-Video signals. A TV can be woken from standby mode and automatically switch to the appropriate AV channel when the S ...

Baud
In telecommunication and electronics, baud (; symbol: Bd) is a common unit of measurement of symbol rate, which is one of the components that determine the speed of communication over a data channel. It is the unit for symbol rate or modulation rate in symbols per second or pulses per second. It is the number of distinct symbol changes (signalling events) made to the transmission medium per second in a digitally modulated signal or a bd rate line code. Baud is related to ''gross bit rate'', which can be expressed in bits per second. If there are precisely two symbols in the system (typically 0 and 1), then baud and bit per second (bit/s) are equivalent. Naming The baud unit is named after Émile Baudot, the inventor of the Baudot code for telegraphy, and is represented according to the rules for SI units. That is, the first letter of its symbol is uppercase (Bd), but when the unit is spelled out, it should be written in lowercase (baud) except when it begins a sentence. It ...

Cassette Player
A cassette deck is a type of tape machine for playing and recording audio cassettes that does not have a built-in power amplifier or speakers, and serves primarily as a transport. It can be a part of an automotive entertainment system, a part of a portable mini system or a part of a home component system. In the latter case it is also called a component cassette deck or just a component deck. A "tape recorder" is a more generic term to identify a device that usually has a self-contained power amplifier and either has a built-in speaker or comes packaged with one. History Origins The first consumer tape recorder to employ a tape reel permanently housed in a small removable cartridge was the RCA tape cartridge, which appeared in 1958 as a predecessor to the cassette format. At that time, reel to reel recorders and players were commonly used by enthusiasts, but required large individual reels and tapes which had to be threaded by hand, making them less-accessible to the casual ...

DIN Connector
The DIN connector is an electrical connector that was standardized by the ' (DIN), the German Institute for Standards, in the early 1970s. The male DIN connectors (plugs) feature a 13.2 mm diameter metal shield with a notch that limits the orientation in which plug and socket can mate. The range of DIN connectors, different only in the configuration of the pins, have been standardized as DIN 41524 / IEC/DIN EN 60130-9 (3-pin at 90° and 5-pin at 45°); DIN 45322 (5-pin and 6-pin at 60°); DIN 45329 / IEC/DIN EN 60130–9 (7-pin at 45°); and DIN 45326 / IEC/DIN EN 60130-9 (8-pin at 45°). In consumer electronics, the term "DIN connector" identifies types of cylindrical connectors that the German Institute for Standards (DIN) had initially standardised for analog audio signals. Some DIN connectors have been used in analog video applications, for power connections, and for digital interfaces, such as the MIDI (DIN 41524), the IBM PC keyboard and the IBM AT keyboard connect ...

AZERTY
AZERTY () is a specific keyboard layout, layout for the characters of the Latin alphabet on typewriter keys and computer keyboard (computing), keyboards. The layout takes its name from the first six letter (alphabet), letters to appear on the first row of alphabetical keys; that is, ( ). Similar to the QWERTZ layout, it is modelled on the English QWERTY layout. It is used in France and Belgium, and even Russia, although each of these countries has its own national variation on the layout. Luxembourg and Switzerland use the Keyboard layout#Switzerland, Swiss QWERTZ keyboard. Most of the residents of Quebec, the mainly French-speaking province of Canada, use a QWERTY keyboard that has been adapted to the French language such as the Multilingual Standard keyboard CAN/CSA Z243.200-92 which is stipulated by the government of Quebec and the Government of Canada. The competing layouts devised for French (e.g., the ZHJAY layout put forward in 1907, Claude Marsan's 1976 layout, the 200 ...

Emulator
In computing, an emulator is Computer hardware, hardware or software that enables one computer system (called the ''host'') to behave like another computer system (called the ''guest''). An emulator typically enables the host system to run software or use peripheral devices designed for the guest system. Emulation refers to the ability of a computer program in an electronic device to emulate (or imitate) another program or device. Many Printer (computing), printers, for example, are designed to emulate Hewlett-Packard, HP LaserJet printers because so much software is written for HP printers. If a non-HP printer emulates an HP printer, any software written for a real HP printer will also run in the non-HP printer emulation and produce equivalent printing. Since at least the 1990s, many video game enthusiasts and hobbyists have used emulators to play classic arcade games from the 1980s using the games' original 1980s machine code and data, which is interpreted by a current-era s ...

Homebrew (video Games)
Homebrew, when applied to video games, refers to games produced by hobbyists for proprietary video game consoles which are not intended to be user-programmable. The official documentation is often only available to licensed developers, and these systems may use storage formats that make distribution difficult, such as ROM cartridges or encrypted CD-ROMs. Many consoles have hardware restrictions to prevent unauthorized development. A non-professional developer for a system intended to be user-programmable, like the Commodore 64, is simply called a ''hobbyist'' (rather than a ''homebrew developer''). Development can use unofficial, community maintained toolchains or official development kits such as Net Yaroze, Linux for PlayStation 2, or Microsoft XNA. Targets for homebrew games are typically those which are no longer commercially relevant or produced, and with lower standards in art quality, such as the Atari 2600, Nintendo Entertainment System, Wii, Nintendo 3DS, Genesis, ...

Semigraphic
Text-based semigraphics or pseudographics is a primitive method used in early text mode video hardware to emulate raster graphics without having to implement the logic for such a display mode. There are two different ways to accomplish the emulation of raster graphics. The first one is to create a low-resolution all points addressable mode using a set of special characters with all binary combinations of a certain subdivision matrix of the text mode character size; this method is referred to as block graphics, or sometimes mosaic graphics. The second one is to use special shapes instead of glyphs (letters and figures) that appear as if drawn in raster graphics mode, sometimes referred to as semi- or pseudo-graphics; an important example of this is box-drawing characters. Semigraphical characters (including some block elements) are still incorporated into the BIOS of any VGA compatible video card, so any PC can display these characters from the moment it is turned on, even whe ...

Schneider Rundfunkwerke
Schneider Rundfunkwerke AG was a German manufacturer of mass market audio equipment. History The origins of the company trace to 1889 in Türkheim, Swabia, Germany, when Felix Schneider founded a company manufacturing industrial woodworking tools. In 1965 the business entered the audio electronics market through the manufacture of radio cabinets During the 1970s and 1980s the Schneider name became associated with audio systems; the company was unusual for a German audio systems manufacturer in that it focused on low cost products rather than the luxury sector. In 1984 computers from the Amstrad company were marketed under the Schneider brand in Germany and central Europe. In 1987 the association with Amstrad ended, and the company produced PC compatible machines from 1988. The '' Gebrüder Steidinger'' company (maker of the Dual turntable line) and brand were acquired from Thomson in 1988, in part to obtain a saleable brand name in France where the large and long established com ...
