Home computing and the gaming industry have their origins in the iconic early 80s hardware, documented here in an homage to an eccentric pioneer

You’ll need a pretty high geek tolerance level for this very detailed and specialised account of Sir Clive Sinclair’s bestselling ZX Spectrum home computer, whose appearance in 1982 with its rubbery keys was thought to be as lovably eccentric as the man himself. But with this he revolutionised the market, educated the British public about the importance of computing, and virtually created the gaming industry from scratch. It was originally to be called the “Rainbow” in homage to its groundbreaking colour graphics; Sinclair instead insisted on “Spectrum” as it was more scientific-sounding.
