JR-BASIC
JR-BASIC is a dialect of the BASIC programming language running on the Matsushita JR series of microcomputers. Although it's its own dialect, it was designed to be mostly compatible with Microsoft BASIC. Since it was developed for low-cost entry-level machines, it featured as few functions as possible, in order to save computer resources. Nevertheless, the interpreter was intended to be compact and efficient, with a feature-rich screen editor supporting direct execution of BASIC instructions. Commands were input by keywords - by pressing a combination of control and alphabet keys, a full command word would be entered. This was faster and more comfortable than typing words letter by letter, as the computer keyboard was poor ( chiclet keyboard). JR-BASIC 1.0 JR-BASIC 1.0 is the original version present on the JR-100 computer, released in 1981,. Specifications Keyboard commands Key combinations allowed the user to enter commands and control the onscreen basic interpreter. JR ...

Matsushita JR Series
The Matsushita JR series was a line of microcomputers produced by Matsushita Electric Industrial (now Panasonic) during the 1980s. Based on the success of the Sharp MZ and NEC PC-8000 series, it was an attempt by Matsushita to enter the personal computer market. The JR series included four computer models: the JR-100, the JR-200, the JR-300 and the JR-800. JR-100 The JR-100マイコン1982年2月号 was released on November 21st, 1981 with a price of 54,800 yen. Like the Hitachi Basic Master and Sharp MZ-80, it was a low-performance, low-priced personal computer offering basic semi-graphic character based graphics, a monochrome display, and minimal sound ability. The CPU was an 8-bit Panasonic MN1800A NMOS microprocessor (compatible with the Motorola MC6802, a slightly improved version of the Motorola MC6800) running at a slow 0.89 MHz, and it came with 16 KB of RAM (expandable to 32 KB). Specifications: *CPU: MN1800A (MC6802 compatible) *Clock speed: 890 KHz *R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Imperative Programming
In computer science, imperative programming is a programming paradigm of software that uses statements that change a program's state. In much the same way that the imperative mood in natural languages expresses commands, an imperative program consists of commands for the computer to perform. Imperative programming focuses on describing ''how'' a program operates step by step, rather than on high-level descriptions of its expected results. The term is often used in contrast to declarative programming, which focuses on ''what'' the program should accomplish without specifying all the details of ''how'' the program should achieve the result. Imperative and procedural programming Procedural programming is a type of imperative programming in which the program is built from one or more procedures (also termed subroutines or functions). The terms are often used as synonyms, but the use of procedures has a dramatic effect on how imperative programs appear and how they are constructed ...

BASIC
BASIC (Beginners' All-purpose Symbolic Instruction Code) is a family of general-purpose, high-level programming languages designed for ease of use. The original version was created by John G. Kemeny and Thomas E. Kurtz at Dartmouth College in 1963. They wanted to enable students in non-scientific fields to use computers. At the time, nearly all computers required writing custom software, which only scientists and mathematicians tended to learn. In addition to the program language, Kemeny and Kurtz developed the Dartmouth Time Sharing System (DTSS), which allowed multiple users to edit and run BASIC programs simultaneously on remote terminals. This general model became very popular on minicomputer systems like the PDP-11 and Data General Nova in the late 1960s and early 1970s. Hewlett-Packard produced an entire computer line for this method of operation, introducing the HP2000 series in the late 1960s and continuing sales into the 1980s. Many early video games trace their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Programming Language
A programming language is a system of notation for writing computer programs. Most programming languages are text-based formal languages, but they may also be graphical. They are a kind of computer language. The description of a programming language is usually split into the two components of syntax (form) and semantics (meaning), which are usually defined by a formal language. Some languages are defined by a specification document (for example, the C programming language is specified by an ISO Standard) while other languages (such as Perl) have a dominant implementation that is treated as a reference. Some languages have both, with the basic language defined by a standard and extensions taken from the dominant implementation being common. Programming language theory is the subfield of computer science that studies the design, implementation, analysis, characterization, and classification of programming languages. Definitions There are many considerations when defini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chiclet Keyboard
A chiclet keyboard or island-style keyboard is a computer keyboard with keys that form an array of small, flat rectangular or lozenge-shaped rubber or plastic keys that look like erasers or "Chiclets", a brand of chewing gum manufactured in the shape of small squares with rounded corners. It is an evolution of the membrane keyboard, using the same principle of a single rubber sheet with individual electrical switches underneath each key, but with the addition of an additional upper layer which provides superior tactile feedback through a buckling mechanism. Since the mid-1980s, chiclet keyboards have been mainly restricted to lower-end electronics, such as small handheld calculators, cheap PDAs and many remote controls, though the name is also used to refer to scissor keyboards with superficially similar appearance. History The term first appeared during the home computer era of the late 1970s to mid-1980s. The TRS-80 Color Computer, TRS-80 MC-10, and Timex Sinclair 2068 wer ...

Text Semigraphics
Text-based semigraphics or pseudographics is a primitive method used in early text mode video hardware to emulate raster graphics without having to implement the logic for such a display mode. There are two different ways to accomplish the emulation of raster graphics. The first one is to create a low-resolution all points addressable mode using a set of special characters with all binary combinations of a certain subdivision matrix of the text mode character size; this method is referred to as block graphics, or sometimes mosaic graphics. The second one is to use special shapes instead of glyphs (letters and figures) that appear as if drawn in raster graphics mode, sometimes referred to as semi- or pseudo-graphics; an important example of this is box-drawing characters. Semigraphical characters (including some block elements) are still incorporated into the BIOS of any VGA compatible video card, so any PC can display these characters from the moment it is turned on, even w ...
