Sharp CE-1650F
The Sharp PC-1600 was a pocket computer introduced by Sharp in 1986 as a successor to the PC-1500. The PC-1600 provided compatibility with its predecessor through the use of a slave CPU that could run assembly language programs targeting the older machine. It could also switch into a compatibility mode so that programs written for the single line display of the PC-1500 could work with the four line display of the PC-1600. PC-1500 peripherals such as the CE-150 cassette interface were also supported.

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.

Calculator Input Methods
There are various ways in which calculators interpret keystrokes. These can be categorized into two main types: * On a single-step or immediate-execution calculator, the user presses a key for each operation, calculating all the intermediate results, before the final value is shown. * On an expression or formula calculator, one types in an expression and then presses a key, such as "=" or "Enter", to evaluate the expression. There are various systems for typing in an expression, as described below. Immediate execution The immediate execution mode of operation (also known as single-step, algebraic entry system (AES) or chain calculation mode) is commonly employed on most general-purpose calculators. In most simple four-function calculators, such as the Windows Calculator, Windows calculator in Standard mode and those included with most early operating systems, each binary operation is executed as soon as the next operator is pressed, and therefore the order of operations in a math ...

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] |
Sharp PC-1500
The Sharp PC-1500 was a pocket computer produced by Sharp between 1981 and 1985. A rebadged version was also sold as the TRS-80 Pocket Computer PC-2. The whole computer was designed around the LH5801, an 8-bit CPU similar to the Zilog Z80, but all laid-out in power-saving CMOS circuits. Equipped with 2KB of on-board RAM, the programming language is BASIC. Later German engineers provided an assembler for the machine. Later even a C compiler followed. An external slot is available and accepts memory (from 4 KB to 32 KB) and ROM modules. Eight versions of this pocket computer with 2 KB memory: *Sharp PC-1500 - Japanese version (1981) *Sharp PC-1500 - Japanese version with blue paint around LCD. Known as PC-1500D (1984) *Sharp PC-1500 - European, Australasian and North American version (1982) *Sharp PC-1500 RP2 - Brazilian version (1982) *HiradasTechnika PTA-4000 - Hungarian licence. *HiradasTechnika PTA-4000+16 - Hungarian licence (with internal 16 KB memory exten ...

RS-232C
In telecommunications, RS-232 or Recommended Standard 232 is a standard originally 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, 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 in computer serial ports and 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 for connection ...

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 ...
