SODA (operating System)
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 hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

History Of Computer Hardware In Eastern Bloc Countries
The history of computing hardware in the Eastern Bloc is somewhat different from that of the Western world. As a result of the CoCom embargo, computers could not be imported on a large scale from Western Bloc. Eastern Bloc manufacturers created copies of Western designs based on intelligence gathering and reverse engineering. This redevelopment led to some incompatibilities with International Electrotechnical Commission (IEC) and IEEE standards, such as spacing integrated circuit pins at of a 25 mm length (colloquially a "metric inch") instead of a standard inch of 25.4 mm. This made Soviet chips unsellable on the world market outside the Comecon, and made test machinery more expensive. History By the end of the 1950s most COMECON countries had developed experimental computer designs, yet none of them had managed to create a stable computer industry. In October 1962 the "Commission for Scientific Problems in Computing" (Комиссия Научные Вопро ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. The only chanc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warsaw
Warsaw ( pl, Warszawa, ), officially the Capital City of Warsaw,, abbreviation: ''m.st. Warszawa'' is the capital and largest city of Poland. The metropolis stands on the River Vistula in east-central Poland, and its population is officially estimated at 1.86 million residents within a greater metropolitan area of 3.1 million residents, which makes Warsaw the 7th most-populous city in the European Union. The city area measures and comprises 18 districts, while the metropolitan area covers . Warsaw is an Alpha global city, a major cultural, political and economic hub, and the country's seat of government. Warsaw traces its origins to a small fishing town in Masovia. The city rose to prominence in the late 16th century, when Sigismund III decided to move the Polish capital and his royal court from Kraków. Warsaw served as the de facto capital of the Polish–Lithuanian Commonwealth until 1795, and subsequently as the seat of Napoleon's Duchy of Warsaw. Th ...

System/360
The IBM System/360 (S/360) is a family of mainframe computer systems that was announced by IBM on April 7, 1964, and delivered between 1965 and 1978. It was the first family of computers designed to cover both commercial and scientific applications and to cover a complete range of applications from small to large. The design distinguished between architecture and implementation, allowing IBM to release a suite of compatible designs at different prices. All but the only partially compatible Model 44 and the most expensive systems use microcode to implement the instruction set, which features 8-bit byte addressing and binary, decimal, and hexadecimal floating-point calculations. The System/360 family introduced IBM's Solid Logic Technology (SLT), which packed more transistors onto a circuit card, allowing more powerful but smaller computers to be built. The slowest System/360 model announced in 1964, the IBM System/360 Model 30, Model 30, could perform up to 34,500 instructions ...

ALGOL 68
ALGOL 68 (short for ''Algorithmic Language 1968'') is an imperative programming language that was conceived as a successor to the ALGOL 60 programming language, designed with the goal of a much wider scope of application and more rigorously defined syntax and semantics. The complexity of the language's definition, which runs to several hundred pages filled with non-standard terminology, made compiler implementation difficult and it was said it had "no implementations and no users". This was only partly true; ALGOL 68 did find use in several niche markets, notably in the United Kingdom where it was popular on International Computers Limited (ICL) machines, and in teaching roles. Outside these fields, use was relatively limited. Nevertheless, the contributions of ALGOL 68 to the field of computer science have been deep, wide-ranging and enduring, although many of these contributions were only publicly identified when they had reappeared in subsequently developed programming lang ...

Mainframe Computer
A mainframe computer, informally called a mainframe or big iron, is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise resource planning, and large-scale transaction processing. A mainframe computer is large but not as large as a supercomputer and has more processing power than some other classes of computers, such as minicomputers, servers, workstations, and personal computers. Most large-scale computer-system architectures were established in the 1960s, but they continue to evolve. Mainframe computers are often used as servers. The term ''mainframe'' was derived from the large cabinet, called a ''main frame'', that housed the central processing unit and main memory of early computers. Later, the term ''mainframe'' was used to distinguish high-end commercial computers from less powerful machines. Design Modern mainframe design is characterized less b ...
