Sage Computer
The AN/FSQ-7 Combat Direction Central, referred to as the Q7 for short, was a computerized command and control system for Cold War ground-controlled interception used in the USAF Semi-Automatic Ground Environment (SAGE) air defense network. The name “AN/FSQ” derives from ''Army-Navy / Fixed Special eQuipment''. An advancement of the pioneering MIT Whirlwind II digital computer design, and manufactured by IBM as prime contractor, the AN/FSQ-7 was the largest discrete computer system ever built. Each of the 24 installed machines weighed 250 tons. The AN/FSQ-7 used a total of 60,000 vacuum tubes (49,000 in the computers) and up to 3 megawatts of electricity, performing about 75,000 instructions per second for networking regional radars. Primary functions Installations in the USAF Semi-Automatic Ground Environment (SAGE) air defense network were configured as duplex systems, using a pair of AN/FSQ-7 computers to provide fault tolerance. One was active at any time, the othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amiga
Amiga is a family of personal computers introduced by Commodore in 1985. The original model is one of a number of mid-1980s computers with 16- or 32-bit processors, 256 KB or more of RAM, mouse-based GUIs, and significantly improved graphics and audio compared to previous 8-bit systems. This includes the Atari ST—released earlier the same year—as well as the Macintosh and Acorn Archimedes. Based on the Motorola 68000 microprocessor, the Amiga differs from its contemporaries through the inclusion of custom hardware to accelerate graphics and sound, including sprite (computer graphics), sprites and a blitter, and a pre-emptive multitasking operating system called AmigaOS. The Amiga 1000 was released in July 1985, but production problems kept it from becoming widely available until early 1986. The best-selling model, the Amiga 500, was introduced in 1987 along with the more expandable Amiga 2000. The Amiga 3000 was introduced in 1990, followed by the Amiga 500 Plus, and Am ...

RS-232
In telecommunications, RS-232 or Recommended Standard 232 is a standard originally introduced in 1960 for serial communication transmission of data. It formally defines signals connecting between a ''DTE'' (''data terminal equipment'') such as a computer terminal, and a ''DCE'' (''data circuit-terminating equipment'' or ''data communication equipment''), such as a modem. The standard defines the electrical characteristics and timing of signals, the meaning of signals, and the physical size and pinout of connectors. The current version of the standard is ''TIA-232-F Interface Between Data Terminal Equipment and Data Circuit-Terminating Equipment Employing Serial Binary Data Interchange'', issued in 1997. The RS-232 standard had been commonly used in computer serial ports and is still widely used in industrial communication devices. A serial port complying with the RS-232 standard was once a standard feature of many types of computers. Personal computers used them for connection ...

Mouse (computing)
A computer mouse (plural mice, sometimes mouses) is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows a smooth control of the graphical user interface of a computer. The first public demonstration of a mouse controlling a computer system was in 1968. Mice originally used two separate wheels to track movement across a surface: one in the X-dimension and one in the Y. Later, the standard design shifted to utilize a ball rolling on a surface to detect motion. Most modern mice use optical sensors that have no moving parts. Though originally all mice were connected to a computer by a cable, many modern mice are cordless, relying on short-range radio communication with the connected system. In addition to moving a cursor, computer mice have one or more buttons to allow operations such as the selection of a menu item on a display. Mice often also feature ...

BCPL
BCPL ("Basic Combined Programming Language") is a procedural, imperative, and structured programming language. Originally intended for writing compilers for other languages, BCPL is no longer in common use. However, its influence is still felt because a stripped down and syntactically changed version of BCPL, called B, was the language on which the C programming language was based. BCPL introduced several features of many modern programming languages, including using curly braces to delimit code blocks. BCPL was first implemented by Martin Richards of the University of Cambridge in 1967. Design BCPL was designed so that small and simple compilers could be written for it; reputedly some compilers could be run in 16 kilobytes. Further, the original compiler, itself written in BCPL, was easily portable. BCPL was thus a popular choice for bootstrapping a system. A major reason for the compiler's portability lay in its structure. It was split into two parts: the front end p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TRIPOS
At the University of Cambridge, a Tripos (, plural 'Triposes') is any of the examinations that qualify an undergraduate for a bachelor's degree or the courses taken by a student to prepare for these. For example, an undergraduate studying mathematics is said to be reading for the ''Mathematical Tripos'', whilst a student of English literature is reading for the ''English Tripos''. In most traditional English universities, a student registers to study one field exclusively, rather than having " majors" or " minors" as in American, Australian, Canadian, or Scottish universities. In practice, however, most degrees may be fairly interdisciplinary in nature, depending on the subject. The multi-part tripos system at Cambridge also allows substantial changes in field between parts; the Natural Sciences Tripos is especially designed to allow a highly flexible curriculum across the sciences. Etymology The word has an obscure etymology, but may be traced to the three-legged stool candid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Business Operating System (software)
The Business Operating System, or BOS, was initially developed as an early cross-platform operating system, originally produced for Intel 8080 and Motorola 6800 computers, then redeveloped for actual businesses and business models. The technology began subsequently for Zilog Z80-based computers, and then later for most microcomputers of the 1980s, then developed into a premium automated software solution for Investors and Asset Managers alike. CAP Ltd, a British company and at the time one of the world's largest Information Technology consulting firms, developed BOS. CAP designed BOS and BOS applications for platform-independence. Via a management buyout (MBO) in 1981, BOS was spun off to three interlinked companies, MPSL (MicroProducts Software Ltd) which looked after the sales and marketing of BOS, MPPL (MicroProducts Programming Ltd) which looked after both the development of BOS and various horizontal software packages, and MicroProducts Training Ltd. BOS was distributed o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PDOS
PDOS is a discontinued multiuser multitasking operating system, written in assembly language developed in the early 1980s by the Eyring Research Institute for the Texas Instruments TMS9900 Introduced in June 1976, the TMS9900 was one of the first commercially available, single-chip 16-bit microprocessors. It implemented Texas Instruments' TI-990 minicomputer architecture in a single-chip format, and was initially used for low-end m ... processor, and later ported to the Motorola 68000 processor. At the time its speed, accuracy and power made it ideal for process control. It was used in system development for education and industrial uses. Eyring also sold application programs (e.g. a statistics package) for the operating system. References Monolithic kernels 68k architecture {{Operating-system-stub ...

Idris (operating System)
Idris is a discontinued multi-tasking, Unix-like, multi-user, real-time operating system released by Whitesmiths, of Westford, Massachusetts. The product was commercially available from 1979 through 1988. Background Idris was originally written for the PDP-11 by P. J. Plauger, who started working on Idris in August 1978. It was binary compatible with Unix V6 on PDP-11, but it could run on non- memory managed systems (like LSI-11 or PDP-11/23) as well. The kernel required 31 KB of RAM, and the C compiler (provided along with the standard V6 toolset) had more or less the same size. Ports Although Idris was initially available for the PDP-11, it was later ported to run on a number of platforms, such as the VAX, Motorola 68000, System/370 and Intel 8086. There was also a version that used bank-switching for memory management, that ran on the Intel 8080. In 1986, David M. Stanhope at Computer Tools International A computer is a machine that can be programmed to carry o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CP/M
CP/M, originally standing for Control Program/Monitor and later Control Program for Microcomputers, is a mass-market operating system created in 1974 for Intel 8080/ 85-based microcomputers by Gary Kildall of Digital Research, Inc. Initially confined to single-tasking on 8-bit processors and no more than 64 kilobytes of memory, later versions of CP/M added multi-user variations and were migrated to 16-bit processors. The combination of CP/M and S-100 bus computers became an early standard in the microcomputer industry. This computer platform was widely used in business through the late 1970s and into the mid-1980s. CP/M increased the market size for both hardware and software by greatly reducing the amount of programming required to install an application on a new manufacturer's computer. An important driver of software innovation was the advent of (comparatively) low-cost microcomputers running CP/M, as independent programmers and hackers bought them and shared their crea ...
