On September 16, 2021 Clive Sinclair died at the age of 81.
Sinclair was known for computers like the ZX80, ZX81, ZX Spectrum und QL (“quantum leap”). Especially the ZX81 and ZX Spectrum were very successful systems. In adition in 1972 he also launched the pocket calculator “Sinclair Executive” which was much smaller than other calculators at that time. In 1983 the “TV80” was launced – a very compact television using a picture tube which displayed the picture to the side whereby the device could be built very flat overall for the conditions at the time.
One invention which was not that successful was the electric vehicle “C5” from 1985 where only 17000 copies got produced for 8 months. Also the digital wrist watch “Black Watch” from 1975 was mostly a disaster – much too short battery life, the danger of destroying the electronics with static charge and inaccurate time which was depending on the current temperature.
Despite the failures, Clive Sinclair’s impact on creating affordable computers for end users should not be underestimated. The ZX81 was revolutionary back then – a personal computer at a price virtually anyone could afford. The ZX Spectrum later became a fixture in the home computer market of that time, alongside the devices from Commodore and Atari.
