SM EVM
SM EVM (СМ ЭВМ, abbreviation of Система Малых ЭВМ—literally System of Mini Computers) are several types of Soviet Union, Soviet and Comecon minicomputers produced from 1975 through the 1980s. Most types of SM EVM are clone (computer science), clones of Digital Equipment Corporation, DEC PDP-11 and VAX. SM-1 and SM-2 are clones of Hewlett-Packard minicomputers. The common operating systems for the PDP-11 clones are translated versions of RSX-11 (ОС РВ) for the higher spec models and RT-11 (РАФОС, ФОДОС) for lower spec models. Also available for the high-end PDP-11 clones is MOS (operating system), MOS, a clone of Unix, UNIX.

Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk (Byelorussian SSR), Tashkent ( Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Govern ...

SM-4
The SM-4 (CM-4) is a PDP-11/40 compatible system, manufactured in the Eastern Bloc in the 1980s. It was very popular in science and technology. They were manufactured in the Soviet Union, Bulgaria and Hungary, beginning in 1975. The standard configuration includes 128 or 256 KB core memory, tape puncher, two RK-05 removable 2.5 MB disks and two RK-05F fixed disks, two TU-10 drives and Videoton VDT-340 terminals ( VT52 non-compatible). The SM-4 processor operates at 900,000 operations per second. The SM-series also includes the SM-3. The SM-3 lacks floating point processing, similar to DEC's PDP 11/40 and 11/34 models. In early production, ferrite core memory is used. It operates at 200,000 operations per second in register-to-register operation. Operating systems commonly used include: * RT-11 (Rafos after partial translation) * RSTS/E * RSX-11 * DSM-11 (DIAMS after partial translations) * DEMOS and MNOS The SM-4 was manufactured in seven configurations, numbers SM-1401 ...

Minicomputers
A minicomputer, or colloquially mini, is a class of smaller general purpose computers that developed in the mid-1960s and sold at a much lower price than mainframe and mid-size computers from IBM and its direct competitors. In a 1970 survey, '' The New York Times'' suggested a consensus definition of a minicomputer as a machine costing less than (), with an input-output device such as a teleprinter and at least four thousand words of memory, that is capable of running programs in a higher level language, such as Fortran or BASIC. The class formed a distinct group with its own software architectures and operating systems. Minis were designed for control, instrumentation, human interaction, and communication switching as distinct from calculation and record keeping. Many were sold indirectly to original equipment manufacturers (OEMs) for final end use application. During the two decade lifetime of the minicomputer class (1965–1985), almost 100 companies formed and only a ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
K 1820
The K 1820, full name RVS K 1820 ({{lang, de, Rechnersystem mit virtuellem Speicher, "computer system with virtual memory"), cipher in the SM EVM of the former COMECON countries SM 1720, is a workstation developed in East Germany. VEB Robotron Elektronik Dresden began development of the K 1820 in 1986 and it went into serial production in 1990. Minicomputer The K 1820 is a clone of the MicroVAX II made by Digital Equipment Corporation (DEC). The import of western 32-bit computers to the COMECON area was impeded by the CoCom technology embargo. As the MicroVAX II CPU is one of the first semiconductor devices which was protected by the Semiconductor Chip Protection Act of 1984, independent development of modern CAD technology based on a 32-bit computer architecture began. Copies of the MicroVAX II were also created in Hungary (MicroSTAR 32 or TPA-11/510) and the Soviet Union (SМ 1702). [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
K 1840
The K 1840, full name RVS K 1840 (, "computer system with virtual memory") is a minicomputer from the German Democratic Republic (GDR). Its development began in August 1985 at VEB Robotron Elektronik in Dresden, and it went into production in 1988. Minicomputer The K 1840 minicomputer is a clone of VAX-11/780 from Digital Equipment Corporation (DEC). The export of western 32-bit minicomputers to Comecon countries was forbidden by the CoCom technology embargo. Therefore one was developed locally, using computer aided design (CAD) technology based on a 32-bit computer architecture. The K 1840 is the first 32-bit computer of the M 32 VAX-compatible minicomputer line. Copies of VAX-11/7xx computers are known also from Czechoslovakia (CM 5152), Hungary (TPA-11/540, 560 and 580), Romania (CORAL 8730) and the Soviet Union (CM 1700). K 1840 has a maximum computing speed of 1.1 MIPS; it can access up to 16 MiB of main memory and up to 4 GiB of virtual memory. The firs ...

SM-1420
The SM-1420 (CM-1420) is a 16 bit DEC PDP-11/45 minicomputer clone, and the successor to SM-4 in Soviet Bloc countries. Under the direction of Minpribor it was produced in the Soviet Union and Bulgaria from 1983 onwards, and is more than twice as fast as its predecessor. Its closest western counterpart is the DEC PDP-11/45, which means that the Soviet technology trailed 11 years behind compared to the Digital Equipment Corporation equivalent machine. The standard package includes 256 KiB MOS memory, two RK-06 disks, two TU-10 decks, CM-6315 barrel or DZM-180 dot-matrix printer from Mera Blonie (Poland), VT52 compatible or VTA-2000-15 (BTA 2000-15) VT100 compatible terminals from Mera Elzab.

Unix
Unix (; trademarked as UNIX) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley ( BSD), Microsoft (Xenix), Sun Microsystems ( SunOS/ Solaris), HP/ HPE ( HP-UX), and IBM (AIX). In the early 1990s, AT&T sold its rights in Unix to Novell, which then sold the UNIX trademark to The Open Group, an industry consortium founded in 1996. The Open Group allows the use of the mark for certified operating systems that comply with the Single UNIX Specification (SUS). Unix systems are characterized by a modular design that is sometimes called the "Unix philosophy". According to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comecon
The Council for Mutual Economic Assistance (, ; English abbreviation COMECON, CMEA, CEMA, or CAME) was an economic organization from 1949 to 1991 under the leadership of the Soviet Union that comprised the countries of the Eastern Bloc#List of states, Eastern Bloc along with a number of socialist states elsewhere in the world. The descriptive term was often applied to all multilateral activities involving members of the organization, rather than being restricted to the direct functions of Comecon and its organs. This usage was sometimes extended as well to bilateral relations among members because in the system of communist international economic relations, multilateral accords typically of a general nature tended to be implemented through a set of more detailed, bilateral agreements. Comecon was the Eastern Bloc's response to the formation in Western Europe of the Marshall Plan and the OEEC, which later became the OECD. Name in official languages of the members History Fou ...
