Re: The story goes..
Umm. What?
The press reported on Clive Sinclair beating Chris Curry about the head with a rolled-up newspaper in The Baron of Beef in Cambridge during the run-up to Christmas 1984, after seeing an ad in it for Acorn that compared their warranty returns with Sinclair's. Curry was a former employee who'd quit in 1978 after a dispute about new computer models and founded Acorn instead.
Sugar and Sinclair didn't meet much and were only seen in public together for press coverage of the sell-off of Sinclair Research's computer business to Amstrad.
