Elwro
Elwro was a Polish company that manufactured mainframe and microcomputers from 1959 until 1989. Its plant was in Wroclaw. Computer models included Odra mainframe systems, and the Elwro 800 Junior microcomputer for education. Overview The Wroclaw Electronic Works (Wrocławskie Zakłady Elektroniczne) were established 6 February 1959; the name ''Elwro'' was derived from the company's telegraphic address. The first model designed at this plant was the vacuum-tube based Odra 1001, released in December 1960; this was a research computer not put into serial production. The next model was the Odra 1002 which was constructed from transistors made in Poland, in 1962. The Elwro factory was responsible for mass production of the tube-based UMC-1 designed at Warsaw University of Technology; twenty-five units were built from 1962 through 1965. Concurrently, design work was proceeding on the Odra 1003 transistor computer, which was faster than the UMC-1, and used much less power. Th ...

List Of ZX Spectrum Clones
The following is a list of clones of Sinclair Research's ZX Spectrum home computer. This list includes both official clones (from Timex Corporation) and many unofficial clones, most of which were produced in Eastern Bloc countries. The list does not include computers which require additional hardware or software to become ZX-compatible. Official The only official clones of the Spectrum were made by Timex. There were three models developed, only two of which were released: Timex Sinclair 2068 The Timex Sinclair 2068 or T/S 2068 (also known as TC 2068 or UK 2086) was a significantly more sophisticated machine than the original Spectrum. The most notable changes were the addition of a cartridge port, an AY-3-8912 sound chip, and an improved ULA giving access to better graphics modes. The T/S 2068 was produced for consumers in the United States, while very similar machines were marketed in Portugal and Poland as the Timex Computer 2068 (TC 2068) and Unipolbrit Komputer 2086 ...

History Of Computing In Poland
The history of Polish computing ( informatics) began during the Second World War with breaking the Enigma machine code by Polish mathematicians. After World War II, work on Polish computers began. Poles made a significant contribution to both the theory and technique of world computing. In the State Institute of Mathematics, established in 1948 (from 1952 at the Polish Academy of Sciences), it was decided to start prospective work on the construction of at least one machine comparable to the American ENIAC. For this purpose, the Mathematical Apparatus Group of this Institute (''pol. Grupa Aparatów Matematycznych, GAM'') was established. The first engineering employee of GAM was , and shortly after he was joined by his fellow students, Romuald Marczyński and Krystyn Bochenek. Logician and statistician Henryk Greniewski became the head of GAM. There were no resources to build such a computer - neither technical facilities, nor electronic equipment, nor experience.

Odra (computer)
Odra was a line of computers manufactured in Wrocław, Poland. The name comes from the Odra river that flows through the city of Wrocław. Overview The production started in 1959–1960. Models 1001, 1002, 1003, 1013, 1103, 1204 were of original Polish construction. Models 1304 and 1305 were functional counterparts of ICL 1905 and 1906 due to software agreement. The last model was 1325 based on two models by ICL. The computers were built at the Elwro manufacturing plant, which was closed in 1989. Odra 1002 was capable of only 100–400 operations per second. In 1962, Witold Podgórski, an employee of Elwro, managed to create a computer game on a prototype of Odra 1003; it was an adaptation of a variant of Nim, as depicted in the film ''Last Year at Marienbad''. The computer could play a perfect game and was guaranteed to win. The game was never distributed outside of the Elwro company, but its versions appeared elsewhere. It was probably the first Polish computer game in his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ICL 1900
ICT 1900 was a family of mainframe computers released by International Computers and Tabulators (ICT) and later International Computers Limited (ICL) during the 1960s and 1970s. The 1900 series was notable for being one of the few non-American competitors to the IBM System/360, enjoying significant success in the European and British Commonwealth markets. Origins In early 1963, ICT was engaged in negotiations to buy the computer business of Ferranti. In order to sweeten the deal, Ferranti demonstrated to ICT the Ferranti-Packard 6000 (FP6000) machine, which had been developed by its Canadian subsidiary Ferranti-Packard, to a design known as Harriac that had been initiated in Ferranti by Harry Johnson and fleshed out by Stanley Gill and John Iliffe. The FP6000 was an advanced design, notably including hardware support for multiprogramming. ICT considered using the FP6000 as their medium-sized processor in the 1965–1968 timeframe, replacing the ICT 1302. Another plan ...

ALGOL
ALGOL (; short for "Algorithmic Language") is a family of imperative computer programming languages originally developed in 1958. ALGOL heavily influenced many other languages and was the standard method for algorithm description used by the Association for Computing Machinery (ACM) in textbooks and academic sources for more than thirty years. In the sense that the syntax of most modern languages is "Algol-like", it was arguably more influential than three other high-level programming languages among which it was roughly contemporary: FORTRAN, Lisp, and COBOL. It was designed to avoid some of the perceived problems with FORTRAN and eventually gave rise to many other programming languages, including PL/I, Simula, BCPL, B, Pascal, and C. ALGOL introduced code blocks and the begin...end pairs for delimiting them. It was also the first language implementing nested function definitions with lexical scope. Moreover, it was the first programming language which gave detail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
COBOL
COBOL (; an acronym for "common business-oriented language") is a compiled English-like computer programming language designed for business use. It is an imperative, procedural and, since 2002, object-oriented language. COBOL is primarily used in business, finance, and administrative systems for companies and governments. COBOL is still widely used in applications deployed on mainframe computers, such as large-scale batch and transaction processing jobs. However, due to its declining popularity and the retirement of experienced COBOL programmers, programs are being migrated to new platforms, rewritten in modern languages or replaced with software packages. Most programming in COBOL is now purely to maintain existing applications; however, many large financial institutions were still developing new systems in COBOL as late as 2006. COBOL was designed in 1959 by CODASYL and was partly based on the programming language FLOW-MATIC designed by Grace Hopper. It was created as part ...

Computer Industry
A computer is a machine that can be programmed to carry out sequences of arithmetic or logical operations (computation) automatically. Modern digital electronic computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. A computer system is a nominally complete computer that includes the hardware, operating system (main software), and peripheral equipment needed and used for full operation. This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems. Simple special-purpose devices like microwave ovens and remote controls are included, as are factory devices like industrial robots and computer-aided design, as well as general-purpose devices like personal computers and mobile devices like smartphones. Computers power the Internet, which links bil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
