Hide information about Sinclair

Sinclair Research Limited was founded by Sir Clive Sinclair in the 1960s to take advantage of a boon in home electronics and the desire to bring electronics projects to the masses.

It started off by selling small projects for people to build at home, including amplifiers and radio kits.  During the late 1970s, a range of calculators came out, with their first home computer, the Sinclair ZX80 being released for under £100 in 1980.

Although still in kit form, it was not until the launch of the ZX81 in 1981, that Sinclair Research began to gain a mass following.  The Sinclair ZX Spectrum (1982) and ill-fated Sinclair QL (1984) soon followed, but the Company's products and name were sold to rival Amstrad in 1986, following financial difficulties due to poor sales of the Sinclair QL, the flat screen pocket TV (TV80) and the first electric car, the Sinclair C5.

Sinclair launched the portable computer the Cambridge Z88 under the name Cambridge Computer Limited.

Sir Clive Sinclair still continues to produce different products today, although a long way from the computer heyday - he has produced electric and folding bicycles, an X1 radio which fits inside your ear, a Wheelchair Drive Unit and even a sub-aqua SEADOO SEA-SCOOTER.
