We were lectured by Herman Hauser who started ARM.  Incredible guy.  They called him "Herman the German", but he was actually Austrian.  ARM got sold for pennies, compared to what incredible technology it was.  He said to us that arm went from 0 to 100m in 3 years which at the time was UK's most successful ever company.  There's a story of bill gates flying to cambridge to get a picture with HH.  He said their big mistake was that they didnt focus on the American market until it was too late.  Still amazing tech.
