SM-4 SAM
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 t ...

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. In total, around 600,000 PDP-11s of all models were sold, making it one of DEC's most successful product lines. The PDP-11 is considered by some experts to be the most popular minicomputer. The PDP–11 included a number of innovative features in its instruction set and additional general-purpose registers that made it easier to program than earlier models in the PDP series. Further, the innovative Unibus system allowed external devices to be more easily interfaced to the system using direct memory access, opening the system to a wide variety of peripherals. The PDP–11 replaced the PDP–8 in many real-time computing applications, although both product lines lived in parallel for more than 10 years. The ease of programming of the PDP–11 made it popular for general-pur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Minicomputers
A minicomputer, or colloquially mini, is a type of general-purpose computer mostly developed from the mid-1960s, built significantly smaller and sold at a much lower price than mainframe computers . By 21st century-standards however, a mini is an exceptionally large machine. Minicomputers in the traditional technical sense covered here are only small relative to generally even earlier and much bigger machines. 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 minicomputer vendor companies formed. Only a half-dozen remained by the mid-1980s. When single-chip CPU microprocessors appeared in the 1970s, the defi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SM EVM
SM EVM (СМ ЭВМ, abbreviation of Система Малых ЭВМ—literally System of Mini Computers) are several types of Soviet and Comecon minicomputers produced from 1975 through the 1980s. Most types of SM EVM are clones of 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, a clone of UNIX Unix (, ; trademarked as UNIX) is a family of multitasking, multi-user 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, a ....

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.

MNOS (operating System)
MNOS (MobilNaya Operatsionnaya Sistema, МобильНая Операционная Система (МНОС), or Portable Operating System) is a Unix-like operating system developed in the Soviet Union. Overview The system is derived from Version 6 Unix and then modified to incorporate features of Berkeley Software Distribution (BSD) Unix. From 1983 until 1986, it enjoyed popularity in the Soviet Union and other Eastern Bloc countries, due to its small size and faster performance than that of other Version 7 Unix (and later BSD Unix-based) alternatives. Its development began in the IPK Minavtoproma in Moscow in 1981, and continued in cooperation with other institutes, including Kurchatov Institute. ''MNOS'' and its alternative, ''DEMOS'' version 1.x, were gradually merged from 1986 until 1990 resulting in the joint OS, ''DEMOS'' version 2.x. ''MNOS'' became the first fully bilingual version of Unix, and uses a proprietary 8-bit Cyrillic script character set, U-code, which was dr ...
