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 family of home computers and was compatible with the VIC-20, Commodore 64 and 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, TI-99 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 home entertain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sega Genesis
The Sega Genesis, known as the outside North America, is a 16-bit Fourth generation of video game consoles, fourth generation home video game console developed and sold by Sega. It was Sega's third console and the successor to the Master System. Sega released it in 1988 in Japan as the Mega Drive, and in 1989 in North America as the Genesis. In 1990, it was distributed as the Mega Drive by Virgin Mastertronic in Europe, Ozisoft in Australasia, and Tec Toy in Brazil. In South Korea, it was distributed by Samsung as the Super Gam*Boy and later the Super Aladdin Boy. Designed by an Research and development, R&D team supervised by Hideki Sato and Masami Ishikawa, the Genesis was adapted from Sega's Sega System 16, System 16 arcade board, centered on a Motorola 68000 processor as the central processing unit, CPU, a Zilog Z80 as a sound controller, and a video system supporting hardware Sprite (computer graphics), sprites, Tile-based video game, tiles, and scrolling.

Jumpman (video Game)
''Jumpman'' is a platform game written by Randy Glover and published by Epyx in 1983. It was first developed for the Atari 8-bit family, and versions were also released for the Commodore 64, Apple II, and IBM PC. The game received very favorable reviews when it was released and was a major hit for its publisher, Automated Simulations. It was so successful that the company renamed itself Epyx, formerly their brand for action titles like ''Jumpman''. Re-creations on other platforms, and new levels for the original versions, continue to appear. ''Jumpman'' was published on diskette, but a version of the game with 12 new levels instead of 30 was released on cartridge as '' Jumpman Junior''. It was available on the Atari 8-bit computers, Commodore 64, and ColecoVision. Gameplay According to the story, the base on Jupiter has been sabotaged by terrorists who have placed bombs throughout the base's three buildings. The object of the game is to defuse all the bombs in a platf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miniature Snap-action Switch
A miniature snap-action switch, also trademarked and frequently known as a micro switch, is an electric switch that is actuated by very little physical force, through the use of a tipping-point mechanism, sometimes called an "over-center" mechanism. Switching happens reliably at specific and repeatable positions of the actuator, which is not necessarily true of other mechanisms. They are very common due to their low cost but high durability, greater than 1 million cycles, and up to 10 million cycles for heavy-duty models. This durability is a natural consequence of the design. The defining feature of micro switches is that a relatively small movement at the actuator button produces a relatively large movement at the electrical contacts, which occurs at high speed (regardless of the speed of actuation). Most successful designs also exhibit hysteresis, meaning that a small reversal of the actuator is insufficient to reverse the contacts; there must be a significant movement in th ...

Suction Cup
A suction cup, also known as a sucker, is a device or object that uses the negative fluid pressure of air or water to adhere to nonporous surfaces, creating a partial vacuum. Suction cups are peripheral traits of some animals such as octopuses and squids, and have been reproduced artificially for numerous purposes. Theory The working face of the suction cup is made of elastic, flexible material and has a curved surface. When the center of the suction cup is pressed against a flat, non-porous surface, the volume of the space between the suction cup and the flat surface is reduced, which causes the air or water between the cup and the surface to be expelled past the rim of the circular cup. The cavity which develops between the cup and the flat surface has little to no air or water in it because most of the fluid has already been forced out of the inside of the cup, causing a lack of pressure. The pressure difference between the atmosphere on the outside of the cup and the low ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern Front (1941)
''Eastern Front (1941)'' is a computer wargame for the Atari 8-bit family created by Chris Crawford and published through the Atari Program Exchange (APX) in 1981. A scenario editor and assembly language source code for the game were also sold by APX. Recreating the Eastern Front during World War II, ''Eastern Front'' covers the historical area of operations during 1941–1942. The player commands German units at the corps level as they invade the Soviet Union in 1941 and fight the computer-controlled Russians. The game simulates terrain, weather, supplies, unit morale, and fatigue. A killer app for Atari computers, ''Eastern Front'' was among APX's best selling games, selling over 60,000 copies. It was widely lauded in the press and was '' Creative Computing''s Game of the Year in 1981. In 1982, it was licensed by Atari for distribution on game cartridge, then rereleased in 1988 in XEGS styled packaging. Gameplay ''Eastern Front'' is a corps-level simulation of the fi ...

Handedness
In human biology, handedness is an individual's preferential use of one hand, known as the dominant hand, due to it being stronger, faster or more Fine motor skill, dextrous. The other hand, comparatively often the weaker, less dextrous or simply less subjectively preferred, is called the non-dominant hand. In a study from 1975 on 7688 children in US grades 1-6, Left handers comprised 9.6% of the sample, with 10.5% of male children and 8.7% of female children being left-handed. Handedness is often defined by one's writing hand, as it is fairly common for people to prefer to do some tasks with each hand. There are examples of true ambidexterity (equal preference of either hand), but it is rare—most people prefer using one hand for most purposes. Most of the current research suggests that left-handedness has an epigenetic marker—a combination of genetics, biology and the environment. Because the vast majority of the population is right-handed, many devices are designed for u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strain Relief
Cable management refers to management of electrical or optical cable in a cabinet or an installation. The term is used for products, workmanship or planning. Cables can easily become tangled, making them difficult to work with, sometimes resulting in devices accidentally becoming unplugged as one attempts to move a cable. Such cases are known as "cable spaghetti", and any kind of problem diagnosis and future updates to such enclosures could be very difficult. Cable management both supports and contains cables during installation, and makes subsequent maintenance or changes to the cable system easier. Products such as cable trays, cable ladders, and cable baskets are used to support a cable through cabling routes. Cable selection The choice of cables is also important; for instance, ribbon cables used to connect Parallel ATA drives to the motherboard can disrupt the airflow inside of computers, making case fans less effective; most SATA cables are more compact and therefo ...

D-connector
The D-subminiature or D-sub is a common type of electrical connector. They are named for their characteristic D-shaped metal shield. When they were introduced, D-subs were among the smallest connectors used on computer systems. Description, nomenclature, and variants A D-sub contains two or more parallel rows of pins or sockets usually surrounded by a D-shaped metal shield that provides mechanical support, ensures correct orientation, and may screen against electromagnetic interference. D-sub connectors have Gender of connectors and fasteners, gender: parts with pin contacts are called ''male connectors'' or ''plugs'', while those with socket contacts are called ''female connectors'' or ''sockets''. The socket's shield fits tightly inside the plug's shield. Panel mounted connectors usually have #4-40 UNC (as designated with the Unified Thread Standard) Jackscrew#In_electronic_connectors, jackscrews that accept screws on the cable end connector cover that are used for locking ...

Membrane Switch
A membrane switch is a custom switch assembly that can open or close the conducting path in an electrical circuit and requires at least one contact made of or attached to a flexible substrate. Its assembly differs from traditional mechanical switches: a membrane switch's construction consists of various thin layers sandwiched together using pressure-sensitive adhesives. Each layer in a membrane switch assembly serves a different purpose, and custom features require the addition of specialty layers. Typical implementations arrange multiple membrane switches across its layered structure to form a keypad interface that allows human interaction to control electronic systems. Unique to membrane switches, they are the only switches that can utilize the benefits of flexible printed electronics. These circuits are generally printed on Polyethylene Terephthalate (PET) or Indium Tin Oxide (ITO) substrates. The ink used for printing the circuit is usually filled with copper, silver, or graphi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Printed Circuit Board
A printed circuit board (PCB; also printed wiring board or PWB) is a medium used in Electrical engineering, electrical and electronic engineering to connect electronic components to one another in a controlled manner. It takes the form of a Lamination, laminated sandwich structure of conductive and insulating layers: each of the conductive layers is designed with an artwork pattern of traces, planes and other features (similar to wires on a flat surface) Chemical milling, etched from one or more sheet layers of copper Lamination, laminated onto and/or between sheet layers of a Insulator (electricity), non-conductive substrate. Electrical components may be fixed to conductive pads on the outer layers in the shape designed to accept the component's terminals, generally by means of soldering, to both electrically connect and mechanically fasten them to it. Another manufacturing process adds Via (electronics), vias: plated-through holes that allow interconnections between layers. ...

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] |
