1970's & 1980's RetroFuturism

Hey folks, I'm looking at starting a project with a Retrofuturistic style - and I need as many sources to pull from as possible. So - what do you think the best Retrofuturism films, books, comics, games are from the 1970's and 1980's?

Just for clarity, I'm leaning into CassetteFuturism.

Cheers!
