This is "Micro Men", an awesome 2009 BBC production about the early pioneer days of micro computing in the United Kingdom, which has lasting repercussions globally until today. It is the story of Clive Sinclair, founder and CEO of Sinclair Radionics, later company Sinclair Research, and Chris Curry, who was working over 13 years for Sinclair until due to some differences they split up.
Chris Curry then together with Hermann Hauser and Andy Hopper founded Acorn Ltd., a fierce competitor for Sinclair on the domestic educational market. Acorn created then in 1983 the ARM CPU, which became ubiquitous today in tablets and smartphones.
Ironically mid of the 80s both companies then were sold, Sinclair to Amstrad (Alan Michael Sugar Trading) and Acorn to Olivetti. Below is first the pure movie.
This is from the 10th anniversary of the movie in 2019, where Chris Curry, Steve Furber and Hermann Hauser - so the original Acorn Ltd. founders - did come together to watch the movie, and gave their comments upon it whenever they wanted to. So in short a "react video" to the movie, which gives some pretty interesting insights. Probably the thing you should watch for some interesting insights if you don't mind the smaller view size of the movie.
Their chat after watching the movie, giving even more insights:
