Back in the mid 1980s, when British TV broadcasters weren't afraid to put science and engineering content on mainstream channels during peak viewing, Channel 4 commissioned a pair of programmes which followed the Ford Cosworth team as they developed a new V6 turbo engine. This was just as electronic engine management was making serious progress, and the programmes (particularly the second) give quite a bit of time to the electronics side of things.
It was surprising just how low budget it was, and just how small the teams were. It looks like the engines are made in some back-street garage compared to the operating theatres of today. Things to watch out for are a high tech digital multimeter, a TRS80 Model 100, a bloke in a suit and tie leaning over a racing engine doing 10,000rpm and Ross Brawn looking like a 16 year old fat spotty kid from the local school who they got in to operate the computer.
The electronics content starts around 10 minutes from the end of episode 1, but if you are into F1 then they are both worth watching.
