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 comme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sinclair Research
Sinclair Research Ltd is a British consumer electronics company founded by Clive Sinclair in Cambridge in the 1970s. In 1980, the company entered the home computer market with the ZX80 at £99.95, at that time the cheapest personal computer for sale in the United Kingdom. A year later, the ZX81 became available through retailers, introducing home computing to a generation, with more that 1.5 million sold. In 1982 the ZX Spectrum was released, becoming the UK's best selling computer, and competing aggressively against Commodore and Amstrad. A combination of the failures of the Sinclair QL computer and the TV80 pocket television led to financial difficulties in 1985, and a year later Sinclair sold the rights to its computer products and brand name to Amstrad. Sinclair Research Ltd continued to exist as a one-man company, marketing Clive Sinclair's inventions.

MTV-1
The MTV-1 Micro TV was the second model of a near pocket-sized television. The first was the Panasonic IC model TR-001 introduced in 1970. The MTV-1 was developed by Clive Sinclair ( Sinclair Radionics Ltd). It was shown to the public at trade shows in London and Chicago in January, 1977, and released for sale in 1978. Development spanned 10 years and included from the UK government in 1976. The MTV-1 used an AEG Telefunken black-and-white, electrostatic deflection cathode ray tube (CRT) and included a rechargeable 4- AA-cell NiCad battery pack. It measured and weighed . It was able to receive either PAL or NTSC transmissions on VHF or UHF, the world's first multi-standard TV. A Welsh company, Wolsey Electronics, manufactured it for Sinclair.

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. It was modelled on, and hoped to replicate the success of the Italian Istituto per la Ricostruzione Industriale (IRI), a public holding company, which was seen as having been a major component of the Italian economic miracle after World War II. In Holland's view, nationalisation had gained a bad name in Britain because only run down or declining industries had been nationalised, so public ownership became associated with failure; the IRI on the other hand was a p ...

Digital Watch
A watch is a timepiece carried or worn by a person. It is designed to maintain a consistent movement despite the motions caused by the person's activities. A wristwatch is worn around the wrist, attached by a watch strap or another type of bracelet, including metal bands or leather straps. A pocket watch is carried in a pocket, often attached to a chain. A stopwatch is a type of watch that measures intervals of time. During most of their history, beginning in the 16th century, watches were mechanical devices, driven by clockwork, powered by winding a mainspring, and keeping time with an oscillating balance wheel. These are known as '' mechanical watches''. In the 1960s the electronic ''quartz watch'' was invented, powered by a battery and keeping time with a vibrating quartz crystal. By the 1980s it had taken over most of the watch market, in what became known as the quartz revolution (or the quartz crisis in Switzerland, whose renowned watch industry it decimate ...

Sinclair Sovereign
The Sinclair Sovereign was a high-end calculator introduced by Clive Sinclair's company Sinclair Radionics in 1976. It was an attempt to escape from the unprofitable low end of the market, and one of the last calculators Sinclair produced. Made with a case of pressed steel that a variety of finishes, it cost between and at a time when other calculators could be purchased for under . A number of factors meant that the Sovereign was not a commercial success, including the cost, high import levies on components, competition from cheaper calculators manufactured abroad, and the development of more power-efficient designs using liquid-crystal displays. Though it came with a five-year guarantee, issues such as short battery life limited its usefulness. The company moved on to producing computers soon afterwards. The design by John Pemberton won a Design Council award, and there are examples of the Sovereign in the Museum of Modern Art in New York. It had a Mostek MK50321N main integ ...

Sinclair Oxford 300
Sinclair Oxford was a range of low-cost scientific calculators manufactured and sold by Sinclair Radionics in England from 1975 until 1976. History In November 1974, Gillette wanted to enter the consumer electronics market, so consulted Sinclair, who designed for them the ''Gillette GPA''. Whilst the GPA was released, Gillette put the product on hold after a short time due to economic and pricing uncertainties. Sinclair would use the GPA design for the Oxford range, the development and tooling of which had been paid for by Gillette. The first model was the ''Oxford 100'', launched in Spring 1975 for (all prices exclude VAT); and essentially the same as the GPA. Both the Gillette GPA and Oxford 100 models used 8 digit displays with red light-emitting diodes (LEDs), 4 functions, 9 volt PP3 batteries, and measured . Models All the Oxford models were similar in appearance; the 150 was introduced in 1975 introducing the ability to calculate percentages and square roots. The ''Oxford ...

Value Added Tax
A value-added tax (VAT or goods and services tax (GST), general consumption tax (GCT)) is a consumption tax that is levied on the value added at each stage of a product's production and distribution. VAT is similar to, and is often compared with, a sales tax. VAT is an indirect tax, because the consumer who ultimately bears the burden of the tax is not the entity that pays it. Specific goods and services are typically exempted in various jurisdictions. Products exported to other countries are typically exempted from the tax, typically via a rebate to the exporter. VAT is usually implemented as a destination-based tax, where the tax rate is based on the location of the customer. VAT raises about a fifth of total tax revenues worldwide and among the members of the Organisation for Economic Co-operation and Development (OECD). As of January 2025, 175 of the 193 countries with UN membership employ a VAT, including all OECD members except the United States. History German indust ...
