Elektronika
Elektronika, also spelt Electronika and Electronica (, "Electronics"), is the brand name used for many different electronic products built by factories belonging to the Soviet Ministry of Electronic Industry, including calculators, electronic watches, portable games, and radios. Many Elektronika designs were the result of efforts by Soviet engineers, who were working for the Soviet military–industrial complex but were challenged with producing consumer goods that were in great shortage in the Soviet Union. The brand is still in use in Belarus. Calculators Most notable is a line of calculators, which started production in 1968. The Elektronika calculators were produced in a variety of sizes and function sets, ranging from large, bulky four-function calculators to smaller models designed for use in schools operating on a special, safer 42V standard (like the MK-SCH-2). As time progressed, Elektronika calculators were produced that supported more advanced calculations, with s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reverse Polish Notation
Reverse Polish notation (RPN), also known as reverse Łukasiewicz notation, Polish postfix notation or simply postfix notation, is a mathematical notation in which operators ''follow'' their operands, in contrast to prefix or Polish notation (PN), in which operators ''precede'' their operands. The notation does not need any parentheses for as long as each operator has a fixed number of operands. The term ''postfix notation'' describes the general scheme in mathematics and computer sciences, whereas the term ''reverse Polish notation'' typically refers specifically to the method used to enter calculations into hardware or software calculators, which often have additional side effects and implications depending on the actual implementation involving a stack. The description "Polish" refers to the nationality of logician Jan Łukasiewicz, who invented Polish notation in 1924. The first computer to use postfix notation, though it long remained essentially unknown outside of G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elektronika 60
The Elektronika 60 () is a computer made in the Soviet Union by Elektronika in Voronezh from 1978 until 1991. It is a rack-mounted system with no built-in display or storage devices. It was usually paired with a 15IE-00-013 terminal and I/O devices. The main logic unit is located on the M2 CPU board. As an unlicensed clone implementation of the DEC PDP-11/23, the Elektronika 60 is generally software-compatible, could use much of the same peripherals, and physically resembles that model. The original implementation of ''Tetris'' was written for the Elektronika 60 by Alexey Pajitnov in 1985. As the Elektronika 60 does not have raster graphics, text characters were used to form the blocks. Technical specifications M2 CPU: * LSI-11 (PDP-11 The PDP–11 is a series of 16-bit minicomputers originally sold by Digital Equipment Corporation (DEC) from 1970 into the late 1990s, one of a set of products in the Programmed Data Processor (PDP) series.

Calculator
An electronic calculator is typically a portable electronic device used to perform calculations, ranging from basic arithmetic to complex mathematics. The first solid-state electronic calculator was created in the early 1960s. Pocket-sized devices became available in the 1970s, especially after the Intel 4004, the first microprocessor, was developed by Intel for the Japanese calculator company Busicom. Modern electronic calculators vary from cheap, give-away, credit-card-sized models to sturdy desktop models with built-in printers. They became popular in the mid-1970s as the incorporation of integrated circuits reduced their size and cost. By the end of that decade, prices had dropped to the point where a basic calculator was affordable to most and they became common in schools. In addition to general-purpose calculators, there are those designed for specific markets. For example, there are scientific calculators, which include trigonometric and statistical calculat ...

Game & Watch
is a series of handheld electronic games developed by Nintendo. Designed by Gunpei Yokoi, the first game, ''Ball'' was released in 1980 and the original production run of the devices continued until 1991. The name Game & Watch reflects their dual functionality: a single game paired with a digital clock on a segmented liquid-crystal display (LCD) screen. The Game & Watch series proved a monumental success, selling a total of 43.4 million units globally, marking Nintendo's first major worldwide success with a video game console. History The Game & Watch was the brainchild of designer Gunpei Yokoi, the head of Nintendo Research & Development 1 (R&D1), who was inspired during a trip on a Shinkansen high-speed train, where he noticed a bored businessman idly pressing buttons on a credit-card-sized pocket calculator. This sparked the idea of a compact, discreet toy for adults to pass the time on public transport. At the time, Nintendo was struggling financially, and R&D1 con ...

Elektronika BK
The Electronika BK is a series of 16-bit PDP-11-compatible home computers developed under the Electronika brand by NPO Scientific Center, then the leading microcomputer design team in the Soviet Union. It is also the predecessor of the more powerful UKNC and DVK micros. Overview First released in 1985 (developed in 1983), they are based on the К1801ВМ1 (Soviet LSI-11-compatible CPU) and were the only ''official'' (government approved and accounted for in economic planning) Soviet home computer design in mass production. They sold for about 600–650 roubles. This was costly, as the average Soviet monthly wage then was about 150 roubles. Despite their cost, they became one of the most popular home computer models in the Soviet Union. Later, in the 1990s, their powerful central processing unit (CPU) and straightforward, easy-to-program design made them popular as demoscene machines. ''BK'' (') is a Russian abbreviation for (bytovoy kompyuter) – domestic (or home) computer. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Programmable Calculator
Programmable calculators are calculators that can automatically carry out a sequence of operations under the control of a stored computer programming, program. Most are Turing complete, and, as such, are theoretically general-purpose computers. However, their user interfaces and programming environments are specifically tailored to make performing small-scale numerical computations convenient, rather than for general-purpose use. The first programmable calculators such as the IBM CPC used punched cards or other media for program storage. Hand-held electronic calculators store programs on magnetic strips, removable read-only memory cartridges, flash memory, or in battery-backed read/write memory. Since the early 1990s, most of these flexible handheld units belong to the class of graphing calculators. Before the mass-manufacture of inexpensive dot-matrix LCDs, however, programmable calculators usually featured a one-line numeric or alphanumeric display. The Big Four manufacturer ...
