Multics-like
Multics ("MULTiplexed Information and Computing Service") is an influential early time-sharing operating system based on the concept of a single-level memory.Dennis M. Ritchie, "The Evolution of the Unix Time-sharing System", Communications of the ACM, Vol. 17, 1984, pp. 365-375. It has been written that Multics "has influenced all modern operating systems since, from microcomputers to mainframes." Initial planning and development for Multics started in 1964, in Cambridge, Massachusetts. Originally it was a cooperative project led by MIT (Project MAC with Fernando Corbató) along with General Electric and Bell Labs. It was developed on the GE 645 computer, which was specially designed for it; the first one was delivered to MIT in January 1967. GE offered their earlier 635 systems with the Dartmouth Time-Sharing System which they called "Mark I" and intended to offer the 645 with Multics as a larger successor. Bell withdrew from the project in 1969 as it became clear it would not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stratus VOS
Stratus VOS (Virtual Operating System) is a proprietary operating system running on Stratus Technologies fault-tolerant computer systems. VOS is available on Stratus's ftServer and Continuum platforms. VOS customers use it to support high-volume transaction processing applications which require continuous availability. VOS is notable for being one of the few operating systems which run on fully lockstepped hardware. During the 1980s, an IBM version of Stratus VOS existed and was called the System/88 Operating System. History VOS was designed from its inception as a high-security transaction-processing environment tailored to fault-tolerant hardware. It incorporates much of the design experience that came out of the MIT/Bell-Laboratories/General-Electric (later Honeywell) Multics project. In 1984, Stratus added a UNIX System V implementation called Unix System Facilities (USF) to VOS, integrating Unix and VOS at the kernel level. In recent years, Stratus has added POSIX-com ...

Domain/OS
Domain/OS is the discontinued operating system used by the Apollo/Domain line of workstations manufactured by Apollo Computer. It was originally launched in 1981 as AEGIS, and was rebranded to Domain/OS in 1988 when Unix environments were added to the operating system. It is one of the early distributed operating systems. Hewlett-Packard supported the operating system for a short time after they purchased Apollo, but they later ended the product line in favor of HP-UX. HP ended final support for Domain/OS on January 1, 2001. AEGIS AEGIS is distinctive mainly for being designed for the networked computer, as distinct from its competitors, which are essentially standalone systems with added network features. The prime examples of this are the file system, which is fully integrated across machines, as opposed to Unix which draws a distinction between file systems on the host system and on others, and the user administration system, which is fundamentally network-based. So basic is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PRIMOS
PRIMOS is a discontinued operating system developed during the 1970s by Prime Computer for its minicomputer systems. It rapidly gained popularity and by the mid-1980s was a serious contender as a mainline minicomputer operating system. With the advent of Personal computer, PCs and the decline of the minicomputer industry, Prime was forced out of the market in the early 1990s, and by the end of 2010 the trademarks for both PRIME and PRIMOS no longer existed. Prime had also offered a customizable real-time OS called RTOS. Internals One feature of PRIMOS was that it, like UNIX, was largely written in a high level language (with callable assembly language library functions available). At first, this language was FORTRAN IV, which was an odd choice from a pure computer science standpoint: no Pointer (computer programming), pointers, no native String (computer science), string type, etc. FORTRAN was, however, the language most known to engineers, and engineers were a big market for ...

GEORGE (operating System)
GEORGE was the name given to a series of operating systems released by International Computers and Tabulators (ICT) in the 1960s, for the ICT 1900 series of computers. These included GEORGE 1, GEORGE 2, GEORGE 3, and GEORGE 4. Initially, the 1900 series machines, like the Ferranti-Packard 6000 on which they were based, ran a simple operating system known as Executive (operating system), Executive, which allowed the system operator to load and run programs from a Teletype Model 33 ASR based system console. In December 1964, ICT set up an Operating Systems Branch to develop a new operating system for the 1906/7. The branch was initially staffed with people being released by the end of work on the Orion Master Program, OMP operating system for the Ferranti Orion. The initial design of the new system, named George after the head of the Basic Programming Division George E. Felton, was based on ideas from the Orion and the spooling system of the Atlas Computer (Manchester), Atlas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ICL VME
VME (''Virtual Machine Environment'') is a mainframe operating system developed by the UK company International Computers Limited (ICL, now part of the Fujitsu group). Originally developed in the 1970s (as VME/B, later VME 2900) to drive ICL's then new 2900 Series mainframes, the operating system is now known as OpenVME incorporating a Unix subsystem, and runs on ICL Series 39 and Trimetra mainframe computers, as well as industry-standard x64 servers. Origins The development program for the New Range system started on the merger of International Computers and Tabulators (ICT) and English Electric Computers in 1968. One of the fundamental decisions was that it would feature a new operating system. A number of different feasibility and design studies were carried out within ICL, the three most notable being: * VME/B (originally System B), targeted at large processors such as the 2970/2980 and developed in Kidsgrove, Staffordshire and West Gorton, Manchester * VME/K ( ...

Computing Utility
Utility computing, or computer utility, is a service provisioning model in which a service provider makes computing resources and infrastructure management available to the customer as needed, and charges them for specific usage rather than a flat rate. Like other types of on-demand computing (such as grid computing), the utility model seeks to maximize the efficient use of resources and/or minimize associated costs. Utility is the packaging of system resources, such as computation, storage and services, as a metered service. This model has the advantage of a low or no initial cost to acquire computer resources; instead, resources are essentially rented. This repackaging of computing services became the foundation of the shift to "on demand" computing, software as a service and cloud computing models that further propagated the idea of computing, application and network as a service. There was some initial skepticism about such a significant shift. However, the new model of co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dartmouth Time-Sharing System
The Dartmouth Time-Sharing System (DTSS) is a discontinued operating system first developed at Dartmouth College between 1963 and 1964. It was the first successful large-scale time-sharing system to be implemented, and was also the system for which the BASIC language was developed. DTSS was developed continually over the next decade, reimplemented on several generations of computers, and finally shut down in 1999. General Electric developed a similar system based on an interim version of DTSS, which they referred to as Mark II. Mark II and the further developed Mark III were widely used on their GE-600 series mainframe computers and formed the basis for their online services. These were the largest such services in the world for a time, eventually emerging as the consumer-oriented GEnie online service. Early history Professors John George Kemeny, John Kemeny and Thomas E. Kurtz, Thomas Kurtz at Dartmouth College purchased a Royal McBee LGP-30 computer around 1959, which was pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GE 645
The GE 645 mainframe computer was a development of the GE 635 for use in the Multics project. This was the first computer that implemented a configurable hardware protected memory system. It was designed to satisfy the requirements of Project MAC to develop a platform that would host their proposed next generation time-sharing operating system (Multics) and to meet the requirements of a theorized computer utility. The system was the first truly symmetric multiprocessing machine to use virtual memory, it was also among the first machines to implement what is now known as a translation lookaside buffer, the foundational patent for which was granted to John Couleur and Edward Glaser. General Electric initially publicly announced the GE 645 at the Fall Joint Computer Conference in November 1965. At a subsequent press conference in December of that year it was announced that they would be working towards "broad commercial availability" of the system. However they would subsequent ...
