Atari 825
Atari 8-bit computer peripherals include floppy drives, printers, modems, and video game controllers for Atari 8-bit computers, which includes the 400/800, XL, XE, and XEGS. Because the Atari 400/800 8-bit computers were bundled with an RF modulator, stringent FCC regulations limiting radio emissions applied. Consequently, the Atari 400/800 systems internal construction use large metal frames as Faraday cages to prevent emissions. This prevents the use of internal cards to add connections for peripherals. To permit easy expansion, Atari developed the SIO (Serial Input/Output) bus. This bus daisy chains together all Atari peripherals into a single string. The Atari computer family was designed to be easy for novice users to expand, with one universal connector plug. Peripherals have their own IDs and can deliver downloadable drivers to the computer during the boot process. However, the additional electronics in these "intelligent" peripherals made them cost more than the "dumb" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Floppy Drive
A floppy disk or floppy diskette (casually referred to as a floppy, a diskette, or a disk) is a type of disk storage composed of a thin and flexible disk of a magnetic storage medium in a square or nearly square plastic enclosure lined with a fabric that removes dust particles from the spinning disk. The three most popular (and commercially available) floppy disks are the 8-inch, 5¼-inch, and 3½-inch floppy disks. Floppy disks store digital data which can be read and written when the disk is inserted into a floppy disk drive (FDD) connected to or inside a computer or other device. The first floppy disks, invented and made by IBM in 1971, had a disk diameter of . Subsequently, the 5¼-inch (133.35 mm) and then the 3½-inch (88.9 mm) became a ubiquitous form of data storage and transfer into the first years of the 21st century. 3½-inch floppy disks can still be used with an external USB floppy disk drive. USB drives for 5¼-inch, 8-inch, and other-size floppy disks are rare t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Modem
The Democratic Movement (, ; MoDem ) is a centre to centre-right political party in France, whose main ideological trends are liberalism and Christian democracy, and that is characterised by a strong pro-Europeanist stance. MoDem was established by François Bayrou to succeed the Union for French Democracy (UDF) and contest the 2007 legislative election, after his strong showing in the 2007 presidential election. Initially named the Democratic Party (''Parti démocrate''), the party was renamed "Democratic Movement", because there was already a small Democratic Party in France. MoDem secured an agreement with La République En Marche! (LRM) — later Renaissance (RE) — in the 2017 legislative election after Bayrou had endorsed the candidacy of Emmanuel Macron in February. The two parties have since been in alliance, as of late named Ensemble. The party's founder and leader Bayrou has served as Prime Minister of France since December 2024.

Numerical Keypad
A numeric keypad, number pad, numpad, or ten key, is the calculator-style group of ten numeric keys accompanied by other keys, usually on the far right side of computer keyboard. This grouping allows quick number entry with right hand, without the need to use both hands on number row of main keyboard. On a standard IBM PC keyboard, numpad has 17 keys, including digits to , (addition), ( subtraction), (multiplication), and ( division) symbols, (decimal point), , and keys. On smaller keyboards (such as those found on laptops), the numeric keypad can be implemented as alternative markings on alphabetic keys (usually --, --, --) or added as a separate unit, that can be connected to a device by means such as USB; some of these may include keys not found on a standard numpad, such as a spacebar or a (or ) key. Sometimes it is necessary to distinguish between a key on the numpad and an equivalent key elsewhere on the keyboard. For example, depending on the software i ...

Light Pen
A light pen is a computer input device in the form of a light-sensitive wand used in conjunction with a computer's cathode-ray tube (CRT) display. It allows the user to point to displayed objects or draw on the screen in a similar way to a touchscreen but with greater positional accuracy. A light pen can work with any CRT-based display, but its ability to be used with LCDs was unclear (though Toshiba and Hitachi displayed a similar idea at the "Display 2006" show in Japan). A light pen detects changes in brightness of nearby screen pixels when scanned by cathode-ray tube electron beam and communicates the timing of this event to the computer. Since a CRT scans the entire screen one pixel at a time, the computer can keep track of the expected time of scanning various locations on screen by the beam and infer the pen's position from the latest time stamps. History The first light pen, at this time still called "light gun", was created around 1951–1955 as part of the Whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atari XEGS
The Atari XE Video Game System (Atari XEGS) is an industrial redesign of the Atari 65XE home computer and the final model in the Atari 8-bit computer series. It was released by Atari Corporation in 1987 and marketed as a home video game console alongside the Nintendo Entertainment System, Sega's Master System, and Atari's own Atari 7800. The XEGS is compatible with existing Atari 8-bit computer hardware and software. Without keyboard, the system operates as a stand-alone game console. With the keyboard, it boots identically to the Atari XE computers. Atari packaged the XEGS as a basic set consisting of only the console and joystick, and as a deluxe set consisting of the console, keyboard, CX40 joystick, and XG-1 light gun. The XEGS release was backed by new games, including ''Barnyard Blaster'' and ''Bug Hunt'', plus cartridge ports of older games, such as '' Fight Night'' (Accolade, 1985), ''Lode Runner'' (Broderbund, 1983), ''Necromancer'' ( Synapse Software, 1982), and ''Ba ...

Atari CX40 Joystick
The Atari CX40 joystick was the first widely used cross-platform game controller. The original CX10 was released with the Atari Video Computer System (later renamed the Atari 2600) in 1977 and became the primary input device for most games on the platform. The CX10 was replaced after a year by the simpler and less expensive CX40. The addition of the Atari joystick port to other platforms cemented its popularity. It was the standard for the Atari 8-bit computers and was compatible with the VIC-20, Commodore 64, Commodore 128, MSX, and later the Atari ST and Amiga. Third-party adapters allowed it to be used on other systems, such as the Apple II, Commodore 16, TI-99/4A, and the ZX Spectrum. The CX40 was so popular during its run that it became as iconic to Atari as the company's "Fuji" logo; it remains a common staple in video game iconography to this day, and is commonly referred to as ''the'' symbol of 1980s video game system design. The CX40 has been called "the pinnacle of hom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atari 2600
The Atari 2600 is a home video game console developed and produced by Atari, Inc. Released in September 1977 as the Atari Video Computer System (Atari VCS), it popularized microprocessor-based hardware and games stored on swappable ROM cartridges, a format first used with the Fairchild Channel F in 1976. The VCS was bundled with two joystick game controller, controllers, a conjoined pair of paddle (game controller), paddle controllers, and a game cartridgeinitially ''Combat (video game), Combat'' and later ''Pac-Man (Atari 2600 video game), Pac-Man''. Sears sold the system as the Tele-Games Video Arcade. Atari rebranded the VCS as the Atari 2600 in November 1982, alongside the release of the Atari 5200. Atari was successful at creating arcade video games, but their development cost and limited lifespan drove Chief executive officer, CEO Nolan Bushnell to seek a programmable home system. The first inexpensive microprocessors from MOS Technology in late 1975 made this feasible. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atari Joystick Port
The Atari joystick port is a computer port used to connect various gaming controllers to game console and home computer systems in the 1970s to the 1990s. It was originally introduced on the Atari 2600 in 1977 and then used on the Atari 400 and 800 in 1979. It went cross-platform with the VIC-20 in 1981, and was then used on many following machines from both companies, as well as a growing list of 3rd party machines like the MSX platform and various Sega consoles. The port, based on the inexpensive 9-pin D-connector, became a '' de facto'' standard through the 1980s and into the 1990s, supported by a wide variety of joysticks and other devices, most commonly paddle controllers, light pens and computer mice. The standard was so engrained that it led to devices like the Kempston Interface that allowed Atari joysticks to be used on the ZX Spectrum. The port was also used for all sorts of non-gaming roles, including the AtariLab interface, modems, numeric keypads, and even a vid ...

Potentiometer
A potentiometer is a three- terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat. The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage); the component is an implementation of the same principle, hence its name. Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment. It is also used in speed control of fans. Potentiometers operated by a mechanism can be used as position transducers, for example, in a joystick. Potentiometers are rarely used to directly control significant power (more than a watt), since the power dissipated in the potentiometer would be comparable to the power in the controlled load. Nomenclature Some terms in the electronics industry used to describe certain types of potentiometers are: * Pot: ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paddle (game Controller)
A paddle is a game controller with a round ''wheel'' and one or more ''fire buttons'', where the wheel is typically used to control movement of the player object along one axis of the video screen. A paddle controller rotates through a fixed arc (usually about 330 Degree (angle), degrees); it has a stop at each end. The name ''paddle'' is derived from the first game that used it, ''Pong'',, being a video game simulation of table tennis, whose racquets are commonly called paddles. Even though the simulated paddles appeared on-screen (as small line segments), it was the hand controllers used to move the line segments that actually came to bear the name. Some famous video games using paddles are ''Pong'', ''Breakout (video game), Breakout'', and ''Night Driver (video game), Night Driver''. Design The paddle wheel is usually mechanically coupled to a potentiometer, so as to generate an output voltage level varying with the wheel's angle relative to a fixed reference position. A ...

Parallel Port
In computing, a parallel port is a type of interface found on early computers ( personal and otherwise) for connecting peripherals. The name refers to the way the data is sent; parallel ports send multiple bits of data at once (parallel communication), as opposed to serial communication, in which bits are sent one at a time. To do this, parallel ports require multiple data lines in their cables and port connectors and tend to be larger than contemporary serial ports, which only require one data line. There are many types of parallel ports, but the term has become most closely associated with the printer port or Centronics port found on most personal computers from the 1970s through the 2000s. It was an industry ''de facto'' standard for many years, and was finally standardized as IEEE 1284 in the late 1990s, which defined the Enhanced Parallel Port (EPP) and Extended Capability Port (ECP) bi-directional versions. Today, the parallel port interface is virtually non ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centronics
Centronics Data Computer Corporation was an American manufacturer of computer printers, now remembered primarily for the parallel interface that bears its name, the Centronics connector. History Foundations Centronics began as a division of Wang Laboratories. Founded and initially operated by Robert Howard (president) and Samuel Lang (vice president and owner of the well known K & L Color Photo Service Lab in New York City), the group produced remote terminals and systems for the casino industry. Printers were developed to print receipts and transaction reports. Wang spun off the business in 1971 and Centronics was formed as a corporation in Hudson, New Hampshire with Howard as president and chairman. The Centronics Model 101 was introduced at the 1970 National Computer Conference in May. The print head used an innovative seven-wire solenoid impact system. Based on this design, Centronics later developed the first dot matrix impact printer (while the first such pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
