In March 1981, Sinclair Computers was renamed '''Sinclair Research Ltd''' and the [[Sinclair ZX81]] was launched. In February 1982, [[Timex Group USA|Timex Corporation]] obtained a license to manufacture and market Sinclair's computers in the [[United States|USA]] under the name [[Timex Sinclair]]. In April the [[ZX Spectrum]] was launched. In July Timex launched the [[Timex Sinclair 1000|TS 1000]] (a version of the ZX81) in the United States. In March 1982 Sinclair Research Ltd made an £8.55m profit on turnover of £27.17m, including a £383,000 government grant to develop a flat screen.

In 1982 Clive Sinclair converted the Barker & Wadsworth [[mineral water]] [[bottling line|bottling factory]] at 25 Willis Road, Cambridge, into the company's new headquarters. (Following Sinclair's financial troubles, the premises were sold to Cambridgeshire County Council in December 1985.)

In January 1983 the ZX Spectrum personal computer was presented at the [[Las Vegas]] [[Consumer Electronics Show]]. In September the Sinclair [[TV80]] pocket [[television]] was launched, but was a commercial failure.

In 1983 the company bought Milton Hall in the village of [[Milton, Cambridgeshire]], for £2m, establishing its ''MetaLab'' research and development facility there.

In late 1983 Timex decided to pull out of the Timex Sinclair venture which, due to strong competition, had failed to break into the United States market. However, Timex computers continued to be produced for several years in other countries. Timex Portugal launched improved versions, the [[Timex Sinclair 2048|TS 2048]] and [[Timex Sinclair 2068|2068]]; that company also developed and launched the [[Timex FDD3000|FDD3000]], a [[floppy disk]] system, although it was not well received by the market.{{Citation needed|date=January 2020}}
