Who made the Sinclair ZX80?

It was made by Sinclair Research, founded by the inventor Sir Clive Sinclair. Besides the MK14, the ZX80 was the first home computer for under £100, supplied in kit form in 1980 for home-assembly. A more expensive assembled version was also available. Sinclair Research went on to produce the more successful ZX81 (1981) and ZX Spectum (1982), but then went into meltdown with three successive product failures: the Sinclair QL computer (1983), the TV80 pocket TV (1984) and finally the Sinclair C5 (1985). Sinclair Research was finally sold to Sir Alan Sugar's Amstrad, while Sir Clive retained Sinclair Research Limited as a one-man company to promote his inventions.
