Cliff Sinclair was born on July 30, 1940. His father and grandfather were engineers. Young Clive had to work a lot after school – the house did not do well. As it turned out, it was an excellent school for him – he repaired radios and amplifiers, and thus learned more about electronics. Before graduating from school, he started selling DIY electronic kits by mail. He was set to earn his first money at the age of 18 as an author at a publishing house that publishes electrical engineering textbooks.
In 1961, Sinclair founded Sinclair Radionics, which sells components for small transistor radios. The Sinclair Executive calculator hit the market next – and it turned out to be a huge hit among the British. The next watch was one of the first electronic watches, but unfortunately it turned out to be so inaccurate that it failed in the market. A historic moment for the British inventor was the era of the home microcomputer. Thanks to the MK14, it appeared on the market, and then the ZX-80 (February 1980) and ZX-81 (1981) were put on the market. They were a huge success, but the biggest breakthrough was the ZX Spectrum from 1982, the successor to the ZX-81, and produced until 1992. Apart from the Commodore 64, it was the most popular cheap computer in the late 1980s and early 1990s in Poland.
After selling the computer company to Amstrad, Sinclair built his last computer in 1987, the Cambridge Z88, which was used primarily by journalists as a typewriter. In 1983, Sinclair was knighted for his services.
Interestingly, in 2010, Sinclair admitted in an interview with “The Guardian” that he does not use personal computers. According to him, the device at that time “has been in operation for a very long time” and has a very large and completely unused memory.
