In January 1985, Sir Clive Sinclair was the most celebrated inventor in Britain. He had put a computer into more than five million homes, sold the first machine in America to break the hundred dollar barrier, and been knighted for it. Eleven months later his vehicle company was in receivership, his personal fortune was gone, and the entire country was laughing at a white plastic tricycle you had to lie down to drive.
This is the full story of how Sinclair rose from factory reject transistors and a rented room in Cambridge to the ZX81, the ZX Spectrum and a hundred million dollar year, and how the Sinclair C5 turned all of it into a punchline in under a year. The Black Watch disaster nobody learned from. The BBC contract lost to a former colleague. The QL announced before it existed. The Christmas that broke the home computer market. The freezing launch day at Alexandra Palace where journalists ended up pedalling. And the five million pound sale to Amstrad that closed the book on the greatest run in British consumer electronics.
If you grew up loading games off cassette tapes and waiting four minutes for the screech to end, this one is for you.

In the 70's Sinclair opened my world, in the 80's it showed me the possibilities, in the 90's it gave me more power and freedom, in the 00's it gave me the internet, in the 2010's it gave me my own webshop which it still operate and run.
All because of a 1K 8-bit memory machine with no sound or color, on a portable tv... Forever grateful to Clive Sinclair.
