Palm M515
The Palm m500 series is a series of handheld personal digital assistants that consisted of three devices: the Palm m500, Palm m505, and Palm m515. The series was a follow-up to the 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 PDAs was released on March 6, 2001. Based on a poll conducted by Palm Computing, it was determined that the Palm V had the "definitive look" of the ideal PDA. Common traits All of the Palm m500 models were based ...

Personal Digital Assistant
A personal digital assistant (PDA) is a multi-purpose mobile device which functions as a personal information manager. Following a boom in the 1990s and 2000s, PDAs were mostly displaced by the widespread adoption of more highly capable smartphones, in particular those based on iOS and Android (operating system), Android in the late 2000s, and thus saw a rapid decline. 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. By the early 2000s, nearly all PDA models had the ability to access the Internet, intranets or extranets via Wi-Fi or wireless WANs, and since then generally included a web browser. Sometimes, instead of buttons, later PDAs employ touchscreen technology. History The first PDA, the Psion Organiser, Organiser, was released in 1984 by Psion (company), Psion, followed by Psion Series 3, Psion's Series 3, in 1991. The latter began to ...

Palm, Inc
Palm, Inc., was an American company that specialized in manufacturing personal digital assistants (PDAs) and developing software. Palm designed the PalmPilot, the first PDA successfully marketed worldwide, and was known for the Treo 600, one of the earlier successful smartphones. Palm developed the Palm OS software for PDAs and smartphones released under its line of Palm (PDA), Palm-branded devices and also licensed to other PDA manufacturers. 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 corpor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Backlight
A backlight is a form of illumination used in liquid-crystal displays (LCDs) that provides light from the back or side of a display panel. LCDs do not produce light on their own, so they require illumination—either from available light, ambient light or a dedicated light source—to create a visible image. Backlights are commonly used in smartphones, computer monitors, and LCD televisions. They are also used in small displays, such as Watch, wristwatches, to enhance readability in low-light conditions. Typical light sources for backlights include light-emitting diodes (LEDs) and cold cathode fluorescent lamps (CCFLs). Simple types of LCDs, such as those used in pocket calculators, are built without an internal light source and rely on external light sources to make the display image visible to the user. However, most LCD screens are designed with an internal light source. These screens consist of multiple layers, with the backlight typically being the first layer from the bac ...

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. As of 2025, 16-bit microcontrollers cost well under a dollar (similar to close in price legacy 8-bit); the cheapest 16-bit microcontrollers cost less than other types including any 8-bit (and are more powerful, and easier to program generally), making 8-bit legacy microcontrollers not worth it for new applicatio ...

Palm Universal Connector
The Universal Connector was a standard port fitted to the bottom of many Palm PDAs 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 was superseded by the Palm Multi-Connector for the final devices released by Palm, this standard added stereo audio output and mono microphone input. Palm ...

Palm V
Palm V is a personal digital assistant (PDA) by 3Com. Released in 1999 by 3Com, the PDA has an aluminum enclosure containing a Dragonball EZ central processing unit (capable of overclocking to 39 MHz) and two megabytes of memory. Measuring tall and less than thick, the device's 16-shade grayscale display has a backlight and increased resolution from the previous-generation Palm III. Unlike that older device, which uses disposable batteries ( AAAs), the Palm V has a built-in rechargeable lithium-ion battery with an expected charge lasting 1–2 weeks. Palm Vs are equipped with a serial port that is electrically though not physically compatible with the EIA-232-D telecommunications standard (the redesigned enclosure design prevents Palm III-compatible accessories from connecting to the port) and a Consumer IR transceiver. Upon launch, the Palm V cost about , though it had reduced to –400 by January 2000 (equivalent to about $– in ). Units sold in ...
