Apple Extended Keyboard
The Apple Extended Keyboard (AEK, model M0115) is a keyboard that was first sold separately alongside the Macintosh II and SE starting in 1987. It was replaced in 1990 by the Apple Extended Keyboard II (AEKII, model M3501) which was pre-packaged with Apple Professional Desktops starting with the Macintosh IIsi. Both versions were very similar, differing primarily with the addition of adjustable height legs in the AEKII and other minor changes. Both used Apple Desktop Bus (ADB) to connect to the host computer, with ports on either side to allow daisy chaining of another input device, typically a computer mouse or trackball. In 1994, Apple would begin shipping the AppleDesign Keyboard (M2980) which featured only one ADB port and which used rubber dome switches rather than Alps Electric switches. This, in turn, led to a market for 3rd party keyboards that replicate some of the AEK feel, with Matias' line of Tactile Pro and Quiet Pro keyboards perhaps being the most notable. U ...

DFMA
DFMA stands for Design for Manufacture and Assembly. DFMA is the combination of two methodologies; Design for Manufacture, which means the design for ease of manufacture of the parts that will form a product, and Design for Assembly, which means the design of the product for ease of assembly deriving creative ideas at the same time. Usage DFMA is used as the basis for concurrent engineering Concurrent engineering (CE) or concurrent design and manufacturing is a work methodology emphasizing the parallelization of tasks (i.e. performing tasks concurrently), which is sometimes called simultaneous engineering or integrated product develo ... studies to provide guidance to the design team in simplifying the product structure, to reduce manufacturing and assembly costs, and to quantify improvements. The practice of applying DFMA is to identify, quantify and eliminate waste or inefficiency in a product design. DFMA is therefore a component of Lean Manufacturing DFMA is also used as a b ...

Frogdesign
frog (styled as ''"frog, part of Capgemini Invent"'') is a global creative and design consultancy founded in 1969 by industrial designer Hartmut Esslinger in Mutlangen, Germany, where it was initially named “esslinger design”. Soon after the company moved to Altensteig, Germany, and then opened a new studio in Palo Alto, California, and ultimately to its current headquarters in San Francisco, California. The company has studios in North and Central America, Europe, and Asia. The name was changed to frog design in 1982 (the name originating from an acronym for Esslinger's home country, the Federal Republic of Germany; it was originally styled exclusively in lower-case as an expression of its belief in a democratic place of work, where ideas are openly and freely shared, and in opposition to the capitalization of nouns in German). The brand was once again restyled as frog in 2011 to signify an expanded portfolio of services that included strategy and organization activation. Th ...

Steven Peart
Stephen or Steven is a common English first name. It is particularly significant to Christians, as it belonged to Saint Stephen ( grc-gre, Στέφανος ), an early disciple and deacon who, according to the Book of Acts, was stoned to death; he is widely regarded as the first martyr (or " protomartyr") of the Christian Church. In English, Stephen is most commonly pronounced as ' (). The name, in both the forms Stephen and Steven, is often shortened to Steve or Stevie. The spelling as Stephen can also be pronounced which is from the Greek original version, Stephanos. In English, the female version of the name is Stephanie. Many surnames are derived from the first name, including Stephens, Stevens, Stephenson, and Stevenson, all of which mean "Stephen's (son)". In modern times the name has sometimes been given with intentionally non-standard spelling, such as Stevan or Stevon. A common variant of the name used in English is Stephan ; related names that have found some curr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Beginning in 1988 with DR-DO ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM PC AT
The IBM Personal Computer/AT (model 5170, abbreviated as IBM AT or PC/AT) was released in 1984 as the fourth model in the IBM Personal Computer line, following the IBM PC/XT and its IBM Portable PC variant. It was designed around the Intel 80286 microprocessor. Name IBM did not specify an expanded form of "AT" on the machine, press releases, brochures or documentation, but some sources expand the term as "Advanced Technology", including at least one internal IBM document. History IBM's 1984 introduction of the AT was seen as an unusual move for the company, which typically waited for competitors to release new products before producing its own models. At $4,000–6,000, it was only slightly more expensive than considerably slower IBM models. The announcement surprised rival executives, who admitted that matching IBM's prices would be difficult. No major competitor showed a comparable computer at COMDEX Las Vegas that year. Features The AT is IBM PC compatible, with the mo ...

Function Keys
A function key is a key on a computer or terminal keyboard that can be programmed so as to cause an operating system command interpreter or application program to perform certain actions, a form of soft key. On some keyboards/computers, function keys may have default actions, accessible on power-on. Function keys on a terminal may either generate short fixed sequences of characters, often beginning with the escape character (ASCII 27), or the characters they generate may be configured by sending special character sequences to the terminal. On a standard computer keyboard, the function keys may generate a fixed, single byte code, outside the normal ASCII range, which is translated into some other configurable sequence by the keyboard device driver or interpreted directly by the application program. Function keys may have abbreviations or pictographic representations of default actions printed on/besides them, or they may have the more common "F-number" designations. History T ...

Keyboard Technology
The technology of computer keyboards includes many elements. Among the more important of these is the switch technology that they use. Computer alphanumeric keyboards typically have 80 to 110 durable switches, generally one for each key. The choice of switch technology affects key response (the positive feedback that a key has been pressed) and pre-travel (the distance needed to push the key to enter a character reliably). Virtual keyboards on touch screens have no physical switches and provide audio and haptic feedback instead. Some newer keyboard models use hybrids of various technologies to achieve greater cost savings or better ergonomics. The modern keyboard also includes a control processor and indicator lights to provide feedback to the user (and to the central processor) about what state the keyboard is in. Plug and play technology means that its 'out of the box' layout can be notified to the system, making the keyboard immediately ready to use without need for further ...

Alps Electric Co
The Alps () ; german: Alpen ; it, Alpi ; rm, Alps ; sl, Alpe . are the highest and most extensive mountain range system that lies entirely in Europe, stretching approximately across seven Alpine countries (from west to east): France, Switzerland, Italy, Liechtenstein, Austria, Germany, and Slovenia. The Alpine arch generally extends from Nice on the western Mediterranean to Trieste on the Adriatic and Vienna at the beginning of the Pannonian Basin. The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn. Mont Blanc spans the French–Italian border, and at is the highest mountain in the Alps. The Alpine region area contains 128 peaks higher than . The altitude and size of the range affect the climate in Europe; in the mountains, precipitation l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Key
The power key, or power button, is a key found on many computer keyboards during the 1980s and into the early 2000s. They were introduced on the first Apple Desktop Bus keyboards in the 1980s and have been a standard feature of many Macintosh keyboards since then. They are also found on an increasing number of Microsoft Windows keyboards, sometimes supplanted with additional keys for sleep. The power key is becoming increasingly rare, as most modern personal computers using USB allow the system to be started up by pressing any key on the keyboard. Mac The Apple Desktop Bus (ADB) was introduced on the Apple IIGS in 1986. This peripheral bus was intended to connect low-speed input devices like keyboards and computer mice. Looking for a low-cost connector, the design team selected the 4-pin mini-DIN connector, which is also used for S-Video. ADB only used one data pin and +5V and ground, leaving one pin free. This was used to implement the ''PSW'' connection, used to turn on th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
