Sinclair Research Ltd
Sinclair Research Ltd is a British consumer electronics company founded by Clive Sinclair in Cambridge. It was originally incorporated in 1973 as Westminster Mail Order Ltd, renamed Sinclair Instrument Ltd, then Science of Cambridge Ltd, then Sinclair Computers Ltd, and finally Sinclair Research Ltd. It remained dormant until 1976, when it was activated with the intention of continuing Sinclair's commercial work from his earlier company Sinclair Radionics, and adopted the name Sinclair Research in 1981. In 1980, Clive Sinclair entered the home computer market with the ZX80 at £99.95, at that time the cheapest personal computer for sale in the United Kingdom. In 1982 the ZX Spectrum was released, becoming the UK's best selling computer, and competing aggressively against Commodore and Amstrad. At the height of its success, and largely inspired by the Japanese Fifth Generation Computer program, the company established the "MetaLab" research centre at Milton Hall near Cambridg ...

Sinclair Radionics
Sinclair Radionics Ltd was a company founded by Sir Clive Sinclair in Cambridge, England which developed hi-fi products, radios, calculators and scientific instruments. History After raising funds to start the business by writing articles for ''Practical Wireless'' magazine, and borrowing £50, Clive Sinclair founded Sinclair Radionics Ltd. on 25 July 1961. Sinclair initially worked alone in the evenings in a room in London (he was still a technical journalist during the day), selling radio kits by mail order. Radios and Hi-Fi Radionics initially developed hi-fi equipment; it released its first product, the Sinclair Micro-amplifier, in December 1962. The assembly and distribution of this product were contracted out to Cambridge Consultants. In 1963 Sinclair Radionics introduced their first radio with the "Sinclair Slimline" in kit form at forty-nine shillings and sixpence (£2.47½). A year later, in 1964, Sinclair released the "X-10" amplifier, one of the first comm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commodore International
Commodore International (other names include Commodore International Limited) was an American home computer and electronics manufacturer founded by Jack Tramiel. Commodore International (CI), along with its subsidiary Commodore Business Machines (CBM), was a significant participant in the development of the home personal computer industry in the 1970s, 1980s and early 1990s. The company developed and marketed the world's best-selling computer, the Commodore 64 (1982), and released its Amiga computer line in July 1985. With quarterly sales ending 1983 of $ (equivalent to $ in ), Commodore was one of the world's largest personal computer manufacturers. History Founding and early years Commodore co-founders Jack Tramiel and Manfred Kapp met in the early 1950s while both employed by the Ace Typewriter Repair Company in New York City. In 1954, they formed a partnership to sell used and reconditioned typewriters and used their profits to purchase the Singer Typewriter Company. ...

Microcomputer
A microcomputer is a small, relatively inexpensive computer having a central processing unit (CPU) made out of a microprocessor. The computer also includes memory and input/output (I/O) circuitry together mounted on a printed circuit board (PCB). Microcomputers became popular in the 1970s and 1980s with the advent of increasingly powerful microprocessors. The predecessors to these computers, mainframes and minicomputers, were comparatively much larger and more expensive (though indeed present-day mainframes such as the IBM System z machines use one or more custom microprocessors as their CPUs). Many microcomputers (when equipped with a keyboard and screen for input and output) are also personal computers (in the generic sense). An early use of the term ''personal computer'' in 1962 predates microprocessor-based designs. ''(See "Personal Computer: Computers at Companies" reference below)''. A ''microcomputer'' used as an embedded control system may have no human-readable input ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chris Curry
Christopher Curry (born 28 January 1946 in Cambridge) is the co-founder of Acorn Computers, with Hermann Hauser and Andy Hopper. He became a millionaire as a result of Acorn's success. In his early career days, he worked at Pye, Royal Radar Establishment and W.R. Grace Laboratories. Then, in April 1966 he joined Sinclair Radionics where he worked for 13 years. He was involved with their hifi products and their Sinclair C5 electric vehicle. In 1972, he helped Sinclair Radionics to launch its first electronic calculator, the Sinclair Executive. He set up Cambridge Processor Unit Ltd. (CPU) in December 1978. Their first product was the Acorn Microcomputer (later called the System 1). In 1983, he co-founded Redwood Publishing with Michael Potter and Christopher Ward and they bought the ''Acorn User'' title. In 1985, he founded General Information Systems Ltd (GIS) and remains the director. In 2012, he announced his latest project for GIS, Care with Canary. Early life Cu ...

National Enterprise Board
The National Enterprise Board (NEB) was a United Kingdom government body. It was set up in 1975 by the Labour government of Harold Wilson, to support the government's interventionist approach to industry. In 1981 the Conservative government of Margaret Thatcher, combined the NEB with the National Research Development Corporation (NRDC) to form the British Technology Group. Background The NEB was the brainchild of the economist Stuart Holland and the Shadow Secretary of State for Industry Tony Benn in the early-1970s, and was modelled on the Italian Istituto per la Ricostruzione Industriale (IRI), which was seen to have successfully restructured the Italian economy after World War II. In its original conception, the NEB was intended to extend public control and ownership of the economy, by taking a stake in the UK's leading manufacturing firms, which would then be required to make planning agreements to meet economic targets. Although the leadership of the Labour Party did not f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shelf Corporation
A shelf corporation, shelf company, or aged corporation is a company or corporation that has had no activity. It was created and left with no activity – metaphorically put on the "shelf" to "age". The company can then be sold to a person or group of persons who wish to start a company without going through all the procedures of creating a new one. Reasons for buying Common reasons for buying a shelf corporation include: * To save the time involved in taking the steps to create a new corporation. * To gain the opportunity to bid on contracts. Some jurisdictions require that a company be in business for a certain length of time to have this ability. * To show corporate longevity in order to attract consumers or investors. * To gain access to corporate credit. These reasons are open to criticism. Many years ago, it would take months to properly incorporate a business. However, it is now quite easy, at least in Australia, Canada, the United States, Western Europe and Dubai, to d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TV80
The Sinclair TV80, also known as the Flat Screen Pocket TV or FTV1, was a pocket television released by Sinclair Research in September 1983. Unlike Sinclair's earlier attempts at a portable television, the TV80 used a flat CRT with a side-mounted electron gun instead of a conventional CRT; the picture was made to appear larger than it was by the use of a Fresnel lens. It was a commercial failure, and did not recoup the £4m it cost to develop; only 15,000 units were sold. ''New Scientist'' warned that the technology used by the device would be short-lived, in view of the liquid crystal display technology being developed by Casio is a Japanese multinational electronics manufacturing corporation headquartered in Shibuya, Tokyo, Japan. Its products include calculators, mobile phones, digital cameras, electronic musical instruments, and analogue and digital watches. It ....

Formal Verification
In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics. Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code. The verification of these systems is done by providing a formal proof on an abstract mathematical model of the system, the correspondence between the mathematical model and the nature of the system being otherwise known by construction. Examples of mathematical objects often used to model systems are: finite-state machines, labelled transition systems, Petri nets, vector addition systems, timed automata, hybrid automata, process algebra, formal semantics of programming languages such as operational semantics, ...

Wafer-scale Integration
Wafer-scale integration (WSI) is a rarely used system of building very-large integrated circuit (commonly called a "chip") networks from an entire silicon wafer to produce a single "super-chip". Combining large size and reduced packaging, WSI was expected to lead to dramatically reduced costs for some systems, notably massively parallel supercomputers. The name is taken from the term very-large-scale integration, the state of the art when WSI was being developed. Overview In the normal integrated circuit manufacturing process, a single large cylindrical crystal ( boule) of silicon is produced and then cut into disks known as wafers. The wafers are then cleaned and polished in preparation for the fabrication process. A photographic process is used to pattern the surface where material ought to be deposited on top of the wafer and where not to. The desired material is deposited and the photographic mask is removed for the next layer. From then on the wafer is repeatedly processed in ...
