Palm M500
The Palm m500 series of handheld personal digital assistants consisted of three devices: the Palm m500, Palm m505, and Palm m515. The series was a follow-up to the popular Palm V series with a similar, though slightly shorter, footprint and form factor. Like the Palm V, the series had metal cases (although the m500 had a plastic back plate) and a 160x160 resolution screen. The distinguishing features common to all in the series are a SD/ MMC expansion slot, faster processor, new faster USB sync interface, new software functionality, new vibrating alarms, new indicator light, and a mechanical fastener vs. hot-glue case construction. Later models introduced an improved version of the color display and more memory. Palm m500 series The Palm m500 series of Palm Pilot PDAs was released on March 6, 2001. Based on a poll conducted by Palm Computing (formerly a division of 3Com), it was determined that the Palm V had the "definitive look" of the ideal PDA. Common traits All of the Palm ...

Personal Digital Assistant
A personal digital assistant (PDA), also known as a handheld PC, is a variety mobile device which functions as a personal information manager. PDAs have been mostly displaced by the widespread adoption of highly capable smartphones, in particular those based on iOS and Android. A PDA has an electronic visual display. Most models also have audio capabilities, allowing usage as a portable media player, and also enabling many of them to be used as telephones. Nearly all modern PDAs can access the Internet, intranets or extranets via Wi-Fi or Wireless WANs, letting them include a web browser. Sometimes, instead of buttons, PDAs employ touchscreen technology. The first PDA, the Organiser, was released in 1984 by Psion, followed by Psion's Series 3, in 1991. The latter began to resemble the more familiar PDA style, including a full keyboard. The term ''PDA'' was first used on January 7, 1992 by Apple Inc. CEO John Sculley at the Consumer Electronics Show in Las Vegas, Nevad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palm Universal Connector
The Universal Connector was a standard port fitted to the bottom of many Palm PDA's from 2001 to 2004 and on units from other manufacturers that licensed Palm technology, including Garmin. Out of the box, it is used to connect to the sync and charge cradle, allowing the Palm to connect to a desktop PC and receive battery power. A range of accessories were also available for the Universal Connector, including folding keyboards, external battery packs, wired and wireless modems, and many more. The Universal Connector cradles were the first synchronization device that used USB to communicate with the host computer, in addition to the older serial port standard. Some Palm devices manufactured between 2001 and 2004 did not use the Universal Connector. For instance, the Tungsten E had a mini-USB connector. The Universal Connector has now been abandoned in favour of a newer standard, the Palm Multi-Connector. Palm Models fitted with the Universal Connector * Tungsten T, T2, T3, C, W ...

Palm, Inc
Palm, Inc. was an American company that specialized in manufacturing personal digital assistants (PDAs) and various other electronics. They were the designer of the PalmPilot, the first PDA successfully marketed worldwide, as well as the Treo 600, one of the first smartphones. Palm developed several versions of Palm OS for PDAs and smartphones. The company was also responsible for the first versions of webOS, the first multitasking operating system for smartphones, and enyo (software), enyo.js, a framework for HTML5 apps. In July 2010, Palm was purchased by Hewlett-Packard (HP) and in 2011 announced a new range of webOS products. However, after poor sales, HP CEO Léo Apotheker announced in August 2011 that it would end production and support of Palm and webOS devices, marking the end of the Palm brand after 19 years. In October 2014, HP sold the Palm trademark to a shelf corporation tied to the Chinese electronics firm TCL Corporation. Shortly afterward, TCL confirmed its plans ...

Palm OS
Palm OS (also known as Garnet OS) was a mobile operating system initially developed by Palm, Inc., for personal digital assistants (PDAs) in 1996. Palm OS was designed for ease of use with a touchscreen-based graphical user interface. It is provided with a suite of basic applications for Personal information manager, personal information management. Later versions of the OS have been extended to support smartphones. Several other licensees List of Palm OS devices, have manufactured devices powered by Palm OS. Following Palm's purchase of the Palm trademark, the currently licensed version from Access Co., ACCESS was renamed ''Garnet OS''. In 2007, ACCESS introduced the successor to Garnet OS, called Access Linux Platform; additionally, in 2009, the main licensee of Palm OS, Palm, Inc., switched from Palm OS to webOS for their forthcoming devices. Creator and ownership Palm OS was originally developed under the direction of Jeff Hawkins at Palm, Inc., Palm Computing, Inc. Palm was ...

Palm (PDA)
Palm was a 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 2018, a San Francisco ...

Backlight
A backlight is a form of illumination used in liquid crystal displays (LCDs). As LCDs do not produce light by themselves—unlike, for example, cathode ray tube (CRT), plasma (PDP) or OLED displays—they need illumination ( ambient light or a special light source) to produce a visible image. Backlights illuminate the LCD from the side or back of the display panel, unlike frontlights, which are placed in front of the LCD. Backlights are used in small displays to increase readability in low light conditions such as in wristwatches, and are used in smart phones, computer displays and LCD televisions to produce light in a manner similar to a CRT display. A review of some early backlighting schemes for LCDs is given in a report ''Engineering and Technology History'' by Peter J. Wild. Simple types of LCDs such as in pocket calculators are built without an internal light source, requiring external light sources to convey the display image to the user. Most LCD screens, however, are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
16-bit
16-bit microcomputers are microcomputers that use 16-bit microprocessors. A 16-bit register can store 216 different values. The range of integer values that can be stored in 16 bits depends on the integer representation used. With the two most common representations, the range is 0 through 65,535 (216 − 1) for representation as an (unsigned) binary number, and −32,768 (−1 × 215) through 32,767 (215 − 1) for representation as two's complement. Since 216 is 65,536, a processor with 16-bit memory addresses can directly access 64 KB (65,536 bytes) of byte-addressable memory. If a system uses segmentation with 16-bit segment offsets, more can be accessed. 16-bit architecture The MIT Whirlwind ( 1951) was quite possibly the first-ever 16-bit computer. It was an unusual word size for the era; most systems used six-bit character code and used a word length of some multiple of 6-bits. This changed with the effort to introduce ASCII, which used a 7-bit code and naturally led ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freescale DragonBall
Motorola/Freescale Semiconductor's DragonBall, or MC68328, is a microcontroller design based on the famous 68000 core, but implemented as an all-in-one low-power system for handheld computer use. It is supported by μClinux. It was designed by Motorola in Hong Kong and released in 1995. The DragonBall's major design win was in numerous devices running the Palm OS platform. However, from Palm OS 5 onwards their use was superseded by ARM-based processors from Texas Instruments and Intel. The processor is capable of speeds of up to 16.58 MHz and can run up to 2.7 MIPS (million instructions per second), for the base 68328 and DragonBall EZ (MC68EZ328) model. It was extended to 33 MHz, 5.4 MIPS for the DragonBall VZ (MC68VZ328) model, and 66 MHz, 10.8 MIPS for the DragonBall Super VZ (MC68SZ328). It is a 32-bit processor with 32-bit internal and external address bus (24-bit external address bus for EZ and VZ variants) and 32-bit data bus. It has many built-in function ...
