Someone will be along in a minute to tell you to watch Micro Men, an amusing and fairly accurate BBC dramatization of the Sinclair/Acorn rivalry :) but I'm here to recommend that you watch the Computer History Museum's interview with Hermann Hauser the erstwhile director of Acorn - he's very charming: https://m.youtube.com/watch?v=Y0sC3lT313Q
I'm fairly sure they've got one with Chris Curry too, but I can't spot it just now.
It's an entertaining watch, although a fair bit of dramatic licence is taken when depicting various anecdotes that would be well-known to readers of The Micro User and similar magazines of the time.
