PenPad
The term PenPad was used as a product name for a number of Pen computing products by different companies in the 1980s and 1990s. The earliest was the ''Penpad'' series of products by Pencept, such as the PenPad M200 handwriting terminal, and the PenPad M320 handwriting/gesture recognition tablet for MS-DOS and other personal computers. Other vendors using the term Penpad in product names include Amstrad and Toshiba. The Amstrad PenPad was an early portable personal digital assistant with handwriting pen input, and a competitor to the Apple Newton. It was an attempt by Amstrad, a UK electronics firm with a history of successful involvement in personal computing, to corner the handheld market in the UK and Europe. PDA600 The Amstrad PenPad, also known by the ''PDA600'' model reference, was launched in March 1993. Positioned as a replacement for a traditional pocket organiser, reviewers remarked on its small size - around 6.3 by 4.5 by 1 inches - and weight of 14 ounces, noting tha ...

Amstrad PenPad PDA600
Amstrad plc was a British consumer electronics company, founded in 1968 by Alan Sugar. During the 1980s, the company was known for its home computers beginning with the Amstrad CPC and later also the ZX Spectrum range after the Sinclair deal, which led it to have a substantial share of the home computer market in Britain. In the following decade it shifted focus towards communication technologies, and its main business during the 2000s was the manufacture of satellite television set-top boxes for Sky, which Amstrad had started in 1989 as the then sole supplier of the emerging Sky TV service. Headquartered in Brentwood, the company was listed on the London Stock Exchange from 1980 to 2008, the year when Sugar stepped down after 40 years. After acquiring Betacom and Viglen, Amstrad was broken up in 1997 but the name was soon revived when successor Betacom plc renamed itself to Amstrad plc. Amstrad was a FTSE 100 Index constituent up until the company was acquired by BSkyB in 200 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pencept
Pencept, Inc. was a company in the 1980s that developed and marketed pen computing. Pencept was noted primarily for the robustness (for the time) of the handwriting and gesture recognition algorithms, and for an emphasis on developing novel user interface approaches for employing gesture recognition and handwriting recognition that would work with existing applications hardware and software. Pencept employed a proprietary technology for on-line character recognition, based on a functional attribute model of human reading. Thus, unlike many other recognition algorithms employed for handwriting recognition, the recognition was generally user-independent and did not involve training to a user's particular writing style. Early products included the PenPad 200 handwriting-only computer terminal that was a direct replacement for the VT-100 and other standard ANSI 3.62 terminals, but with a digitizing tablet and electronic pen and no keyboard. With the advent of the IBM personal com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pen Computing
Pen computing refers to any computer user-interface using a digital pen or Stylus (computing), stylus and Graphics tablet, tablet, over input devices such as a keyboard or a mouse. Historically, pen computing (defined as a computer system employing a user-interface using a pointing device plus handwriting recognition as the primary means for interactive user input) predates the use of a mouse and graphical display by at least two decades, starting with the Stylator and RAND Tablet systems of the 1950s and early 1960s. General techniques User interfaces for pen computing can be implemented in several ways. Current systems generally employ a combination of these techniques. Pointing/locator input The tablet and Stylus (computing), stylus are used as pointing devices, such as to replace a mouse. While a mouse is a ''relative'' pointing device (one uses the mouse to "push the cursor around" on a screen), a tablet is an ''absolute'' pointing device (one places the stylus where th ...

Tablet Computer
A tablet computer, commonly shortened to tablet, is a mobile device, typically with a mobile operating system and touchscreen display processing circuitry, and a rechargeable battery in a single, thin and flat package. Tablets, being computers, have similar capabilities, but lack some input/output (I/O) abilities that others have. Modern tablets largely resemble modern smartphones, the only differences being that tablets are relatively larger than smartphones, with screens or larger, measured diagonally, and may not support access to a cellular network. Unlike laptops (which have traditionally run off operating systems usually designed for desktops), tablets usually run mobile operating systems, alongside smartphones. The touchscreen display is operated by Gesture recognition, gestures executed by finger or digital pen (stylus), instead of the Computer mouse, mouse, touchpad, and Keyboard (computing), keyboard of larger computers. Portable computers can be classified according ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PCMCIA
The Personal Computer Memory Card International Association (PCMCIA) was an industry consortium of computer hardware manufacturers from 1989 to 2009. Starting with the PCMCIA card in 1990 (the name later simplified to ''PC Card''), it created various standards for peripheral interfaces designed for laptop computers. History PCMCIA was based on the original initiative of the British mathematician and computer scientist Ian H. S. Cullimore, one of the founders of the Sunnyvale-based Poqet Computer Corporation, who was seeking to integrate some kind of memory card technology as storage medium into their early DOS-based palmtop PCs, when traditional floppy drives and harddisks were found to be too power-hungry and large to fit into their battery-powered handheld devices. When in July 1989, Poqet contacted Fujitsu for their existing but still non-standardized SRAM memory cards, and Intel for their flash technology, the necessity and potential of establishing a worldwide mem ...

Palm (PDA)
Palm is a now discontinued line of personal digital assistants (PDAs) and mobile phones developed by California-based Palm, Inc., originally called Palm Computing, Inc. Palm devices are often remembered as "the first wildly popular handheld computers," responsible for ushering in the smartphone era. The first Palm device, the PalmPilot 1000, was released in 1996 and proved to be popular. It led a growing market for portable computing devices where previous attempts such as Apple's Newton failed or others like Hewlett-Packard's 200LX only serving a niche target market. Most of Palm's PDAs and mobile phones ran the in-house Palm OS software, which was later also licensed to other OEMs. A few devices ran on Microsoft's Windows Mobile. In 2009 Palm OS's successor webOS was released, first shipping with the Palm Pre. In 2011 Hewlett-Packard discontinued the Palm brand and started releasing new devices under the HP brand, but discontinued its hardware later that same year. In 2 ...

Tandy Corporation
Tandy Corporation was an American family-owned Retail, retailer based in Fort Worth, Texas that made leather goods, operated the RadioShack chain, and later built personal computers. Tandy Leather was founded in 1919 as a leather supply store. By the end of the 1950s, under the tutelage of then-CEO Charles Tandy, the company expanded into the hobby market, making leather moccasins and coin purses, making huge sales among Scouts, leading to a fast growth in sales. Aiming to broaden the company horizon, Charles Tandy acquired a number of craft retail companies, including RadioShack in 1963, then an almost bankrupt chain of electronics stores in Boston. In the 1970s and 1980s, now led by John V. Roach, John Roach as CEO, the corporation started to invest into the personal computer market following the introduction of the popular TRS-80; it was one of the pioneers in the rising personal computer industry, being lauded by the magazine ''Financial World'' as "the driving force at th ...

RS-232
In telecommunications, RS-232 or Recommended Standard 232 is a standard introduced in 1960 for serial communication transmission of data. It formally defines signals connecting between a ''DTE'' (''data terminal equipment'') such as a computer terminal or PC, and a ''DCE'' ('' data circuit-terminating equipment'' or '' data communication equipment''), such as a modem. The standard defines the electrical characteristics and timing of signals, the meaning of signals, and the physical size and pinout of connectors. The current version of the standard is ''TIA-232-F Interface Between Data Terminal Equipment and Data Circuit-Terminating Equipment Employing Serial Binary Data Interchange'', issued in 1997. The RS-232 standard had been commonly used with serial ports and serial cables. It is still widely used in industrial communication devices. A serial port complying with the RS-232 standard was once a standard feature of many types of computers. Personal computers used them ...

Personal Computer
A personal computer, commonly referred to as PC or computer, is a computer designed for individual use. It is typically used for tasks such as Word processor, word processing, web browser, internet browsing, email, multimedia playback, and PC game, gaming. Personal computers are intended to be operated directly by an end user, rather than by a computer expert or technician. Unlike large, costly minicomputers and mainframes, time-sharing by many people at the same time is not used with personal computers. The term home computer has also been used, primarily in the late 1970s and 1980s. The advent of personal computers and the concurrent Digital Revolution have significantly affected the lives of people. Institutional or corporate computer owners in the 1960s had to write their own programs to do any useful work with computers. While personal computer users may develop their applications, usually these systems run commercial software, free-of-charge software ("freeware"), which i ...

Serial Port
A serial port is a serial communication Interface (computing), interface through which information transfers in or out sequentially one bit at a time. This is in contrast to a parallel port, which communicates multiple bits simultaneously in Parallel communication, parallel. Throughout most of the history of personal computers, data has been transferred through serial ports to devices such as modems, computer terminal, terminals, various peripherals, and directly between computers. While interfaces such as Ethernet, FireWire, and USB also send data as a serial Stream (computing), stream, the term ''serial port'' usually denotes Computer hardware, hardware compliant with RS-232 or a related standard, such as RS-485 or RS-422. Modern consumer personal computers (PCs) have largely replaced serial ports with higher-speed standards, primarily USB. However, serial ports are still frequently used in applications demanding simple, low-speed interfaces, such as industrial automation sys ...
