Founding and early years
On 25 July 1961, Clive Sinclair founded his first company, Sinclair Radionics Ltd. in
CambridgeThe city of Cambridge is a university town and the administrative centre of the county of Cambridgeshire, England. It lies in East Anglia about north of London. Cambridge is at the heart of the high-technology centre known as Silicon Fen – a play on Silicon Valley and the fens surrounding the...
. Sinclair Radionics developed hifi products, radios, calculators and scientific instruments. When it became clear that Radionics was failing, he took steps to ensure that he would be able to continue to pursue his commercial goals: in February 1975, he changed the name of Ablesdeal Ltd. (an off-the-shelf company he bought in September 1973 for just such an eventuality) to Westminster Mail Order Ltd; this was changed to Sinclair Instrument Ltd in August 1975.

and some parts taken from an earlier Sinclair calculator. Curry was impressed and encouraged Sinclair to adopt this as a product; an agreement was reached with Williamson but no contract was ever signed. National Semiconductor had offered to redesign the project so that it used only their components and they also offered to manufacture the boards.
In June 1978, Science of Cambridge launched the microcomputer in kit form, marketed as the

Commercial success and home computers
In March 1981, Sinclair Computers was renamed
Sinclair Research Ltd and the

in May of the year (in 1982 it had upheld complaints about delays in shipping Spectrums). Especially severe were allegations that it was cashing cheques months before machines were shipped. The QL was nowhere near as successful as Sinclair's earlier computers. In the autumn Sinclair were still publicly predicting it would be a "million seller", with 250,000 sold by the end of the year. QL production was suspended in February 1985, and the price was halved by the end of the year.
The ZX Spectrum+, a repackaged ZX Spectrum with a QL-like keyboard, was launched in October 1984 and appeared on

's shelves the day after release. Retailers stocked the machine in large numbers in expectation of good Christmas sales. However the machine did not sell in the numbers expected and, because retailers still had unsold stock, Sinclair's income from orders dipped alarmingly in January. The Spectrum+ had the same technical specifications as the original Spectrum. However, an enhanced model, the ZX Spectrum 128, was launched in Spain in September 1985, with development funded by the Spanish distributor Investronica. However, the UK launch was delayed until January 1986, due to large unsold stocks of previous models held by retailers.
At the January 1985 Las Vegas Consumer Electronics Show, Sinclair re-entered the United States market, announcing the "FM Wristwatch Radio", an LCD wristwatch with a

Return to invention
Since 1986 the company has continued to exist, but in a completely different form than it did in the early 1980s. In 1993, 1994 and 1995 Sinclair made continuing losses on decreasing turnover, and began to worry investors since Clive Sinclair himself was using his own personal wealth to fund his inventions. By 1990 Sinclair's entire staff had been reduced to Sinclair himself, a salesperson/administrator, and an R&D employee. By 1997 reportedly only Sinclair on his own was working at his company.
