Sharp Corporation
is a Japanese multinational corporation that designs and manufactures electronic products, headquartered in Sakai-ku, Sakai, Osaka Prefecture. Since 2016 it has been majority owned by the Taiwan-based Foxconn Group. Sharp employs more than 50,000 people worldwide. The company was founded in September 1912 in Tokyo and takes its name from one of its founder's first Ever-Sharp mechanical pencil, which was invented by Tokuji Hayakawa in 1915. History Early years 1912–1945 In 1912, Tokuji Hayakawa founded a metal workshop in Tokyo. The first of his many inventions was a snap buckle named 'Tokubijo'. Another of his inventions was the Ever-Ready Sharp mechanical pencil in 1915. The product became one of the first internationally available mechanical pencils (while concurrent US design replaced it soon and became a modern type), and due to this big success the Sharp Corporation derived its name from it. After the pencil business was destroyed by the 1923 Great Kantō earthquak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pocket Computer
A pocket computer was a 1980s-era user programmable calculator-sized computer that had fewer screen lines, Some had only one line and often fewer characters per line, than the Pocket-sized computers introduced beginning in 1989. Manufacturers included Casio, Hewlett-Packard, Sharp, Tandy/Radio Shack (selling Casio and Sharp models under their own TRS line) and many more. The last Sharp pocket computer, the PC-G850V (2001) is programmable in C, BASIC, and Assembler. An important feature of pocket computers was that all programming languages were available for the device itself, not downloaded from a cross-compiler on a larger computer. The programming language was usually BASIC.

Tandy Computers
Tandy Corporation was an American family-owned leather goods company based in Fort Worth, Texas, United States. 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. Entering the 1960s, 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 1980s, now led by John Roach as CEO, the corporation started to invest into the personal computer market, being one of the pioneers in the personal computer race, being lauded by the magazine ''Financial World'' as "the driving force at the front-running company in the red-hot personal computer race." In 2000, the Tandy Corporation name was dropped and the entity became t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tandy Pocket Computer
The Tandy Pocket Computer or TRS-80 Pocket Computer is one of a line of 1980s small pocket computers—calculator-sized programmable computing devices—sold by Tandy Corporation under the "''Tandy''" or "''Radio Shack TRS-80''" brands. Although named after the TRS-80 line of computers, they were not compatible with it and did not use the Z-80 CPU. Computers in the line were actually rebadged Sharp and Casio devices with different model names. They were given designations from PC-1 to PC-8. The PC-1, PC-2, PC-3 and PC-8 are Sharp devices, while the PC-4, PC-5, PC-6 and PC-7 were designed by Casio. History, lineage and nomenclature Although not branded as such, the original TRS-80 Pocket Computer later became known as the PC-1, as subsequent models were labelled PC-2 through PC-8. Some were made by Sharp, and the rest by Casio (PC-4 through PC-7). The PC-2 had four colored ball point pens and could print or plot on plain paper. The other print-capable models all used th ...

Sharp Pocket Computer Character Sets
The Sharp pocket computer character sets are a number of 8-bit character sets used by various Sharp pocket computers and calculators in the 1980s and mid 1990s. Character sets PC-12xx and PC-14xx series The Sharp PC-14xx series (like the Sharp PC-1403 (1986), PC-1403H or PC-1475) uses an 8-bit extended ASCII character set. With minor exceptions the lower half resembles the 7-bit ASCII character set. The upper half contains a full set of half-width Katakana glyphs as well as a number of graphical and mathematical symbols. The Japanese glyphs are not documented and are available only after enabling an undocumented ''Japanese mode''. PC-150x series The Sharp PC-1500 series uses a 7-bit character set derived from ASCII. Differences show the Unicode code point below the glyph. PC-160x series The Sharp PC-1600 supports two character sets. In "MODE 0", the character set resembles code page 437, whereas in "MODE 1" certain code points are changed to become compatible with ...
