Sir Clive Sinclair's life in computing
Sir Clive Sinclair's ZX Spectrum computers were in large part responsible for creating a generation of programmers back in the 1980s, when the machines and their clones became best-sellers in the UK, Russia and elsewhere.
Many of today's forty-somethings got a first taste for video gaming with Spectrum classics such as Atic Atac, Jet Set Willy and Manic Miner.
But while such titles are remembered with fondness, it's easy to forget that back in 1982 Sir Clive was taken seriously when he claimed his technology was set to surpass IBM's PC platform to become the dominant force in home computing.
The BBC's Leo Kelion spoke to Sir Clive Sinclair about his life in computing.
