Psion Siena
The Psion Siena is a personal digital assistant made by Psion PLC and was released in 1996. Two versions were released, one with 512 kB of memory and a second with 1 MB. The main power is provided by two AAA batteries and the backup power by one cell-style CR1620 battery. The batteries are held in a compartment below a detachable casing in the top of the device. It has no socket for an external power source. The Siena was of the same generation as the Psion Series 3 but it has a smaller size liquid-crystal display (LCD, 240 x 160 pixels) and a separate numeric keypad next to the screen. The Siena uses the same 16-bit NEC V30H processor as its predecessor the Series 3a. Although the Siena shares binary compatibility with the Series 3, many programs had to be modified due to the reduced sizes of memory and display. Unlike the Series 3, the Siena has no bay for removable solid state disk drives; however, an external drive device is available which connects via an RS-232 serial por ...

Psion Series 5
The Psion Series 5 was a personal digital assistant (PDA) from Psion. It came in two main variants, the ''Series 5'' (launched in 1997) and the ''Series 5mx'' (1999), the latter having a faster processor, clearer liquid crystal display (LCD), and updated software. There was also a rare ''Series 5mx Pro'', which differed only in having the operating system (OS) loaded into random-access memory (RAM) and hence upgradeable. Ericsson marketed a version of the Series 5mx renamed as ''MC218''. The Psion Series 5 was a major upgrade from the Psion Series 3. A Psion Series 4 does not exist, due to Psion's concern of tetraphobia in their Asian markets. The external appearance of the Psion Series 5 and the Psion Series 5mx are broadly similar, but their mainboards and other internal components were different and not interchangeable. The screens are not interchangeable because of different screen cables. The Series 5 was the first to feature a unique sliding clamshell design, whereby the ...

Anarky
Anarky is a supervillain appearing in American comic books published by DC Comics. Co-created by Alan Grant and Norm Breyfogle, he first appeared in ''Detective Comics'' #608 (November 1989), as an adversary of Batman. Anarky is introduced as Lonnie Machin, a child prodigy with knowledge of radical philosophy and driven to overthrow governments to improve social conditions. Stories revolving around Anarky often focus on political and philosophical themes. The character, who is named after the philosophy of anarchism, primarily espouses anti-statism and attacks capitalism; however, multiple social issues have been addressed through the character, including environmentalism, antimilitarism, economic inequality, and political corruption. Inspired by multiple sources, early stories featuring the character often included homages to political and philosophical texts, and referenced anarchist philosophers and theorists.

Anarky (comic Book)
''Anarky'' was a short-lived American comic book series published by DC Comics, as a limited series between May and August of 1997, and as an ongoing series between May and December of 1999. It was written by Alan Grant, with pencils by Norm Breyfogle, and inks by Josef Rubinstein. The comic was a spin-off title derived from the '' Batman'' franchise, and followed the adventures of Anarky, an antagonist of the Batman character. Although Anarky had originally been created to reflect the philosophy of anarchism, the primary influence on both volumes was Neo-Tech, a philosophy developed by Frank R. Wallace. The comic was overtly political in nature, exploring a number of themes including antimilitarism, homelessness, and political corruption. Publication history ''Anarky'' Following the comic book industry crash of 1996, Norm Breyfogle was unemployed and looking for work.

Psion 3
The Psion Series 3 range of personal digital assistants were made by Psion PLC. The four main variants are the ''Psion Series 3'' (1991), the ''Psion Series 3a'' (1993), the ''Psion Series 3c'' (1996), and the ''Psion Series 3mx'' (1998), all sized . Further, a Psion Series 3a variant with factory installed software for the Russian language was called a ''Psion Series 3aR'', and Acorn Computers sold renamed versions of the Psion Series 3 and 3a marketed as the ''Acorn Pocket Book'' and ''Acorn Pocket Book II''. The Psion Series 3 range was regarded in 2009 by writer Charles Stross as an unsurpassed PDA because of its long battery life (20 to 35 hours), its stable and versatile software, and its durable hardware. Others describe over twenty years of daily use with models such as the Psion 3mx. About 1.5 million Psion 3s were made. The prices were 128 kB at and 256 kB at . The Psion Series 3 models were a major advance on the Psion Organiser. They had an original way of managi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serial Port
In computing, a serial port is a serial communication 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. Throughout most of the history of personal computers, data has been transferred through serial ports to devices such as modems, terminals, various peripherals, and directly between computers. While interfaces such as Ethernet, FireWire, and USB also send data as a serial stream, the term ''serial port'' usually denotes 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 systems, scientific instruments, point of sale systems and some industrial and consumer ...

16-bit Computing
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 le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liquid-crystal Display
A liquid-crystal display (LCD) is a flat-panel display A flat-panel display (FPD) is an electronic display used to display visual content such as text or images. It is present in consumer, medical, transportation, and industrial equipment. Flat-panel displays are thin, lightweight, provide better l ... or other Electro-optic modulator, electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directly but instead use a backlight or reflector (photography), reflector to produce images in color or monochrome monitor, monochrome. LCDs are available to display arbitrary images (as in a general-purpose computer display) or fixed images with low information content, which can be displayed or hidden. For instance: preset words, digits, and seven-segment displays, as in a digital clock, are all good examples of devices with these displays. They use the same basic technology, exc ...
