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 ...

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.

Its products include calculators, mobile phones, digital cameras, electronic musical instruments, and analogue and digital watches. It was founded in 1946, and in 1957 introduced the world's first entirely compact electronic calculator. It was an early digital camera innovator, and during the 1980s and 1990s, the company developed numerous affordable home electronic keyboards for musicians along with introducing the world's first mass-produced digital watches. History Casio was established as Kashio Seisakujo in April 1946 by Tadao Kashio ( 樫尾忠雄 1917–1993), an engineer specializing in fabrication technology. Kashio's first major product was the yubiwa pipe, a finger ring that would hold a cigarette, allowing the wearer to smoke the cigarette down to its nub while also leaving the wearer's hands free. Japan was impoverished immediately following World War II, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lower-case
Letter case is the distinction between the letters that are in larger uppercase or capitals (or more formally ''majuscule'') and smaller lowercase (or more formally ''minuscule'') in the written representation of certain languages. The writing systems that distinguish between the upper and lowercase have two parallel sets of letters, with each letter in one set usually having an equivalent in the other set. The two case variants are alternative representations of the same letter: they have the same name and pronunciation and are treated identically when sorting in alphabetical order. Letter case is generally applied in a mixed-case fashion, with both upper and lowercase letters appearing in a given piece of text for legibility. The choice of case is often prescribed by the grammar of a language or by the conventions of a particular discipline. In orthography, the uppercase is primarily reserved for special purposes, such as the first letter of a sentence or of a proper noun (ca ...
