I'm reminded of the film The Year We Make Contact [1984] the sequel to 2001 A Space Odyssey and set nine years later! The Soviets and the Americans have to join up their capsules-something that happened later in real life. When the Americans leave their shiny computerised domain they find that the Russian cabin is a cross between an Edwardian Gents Toilet and an old fashioned submarine ie all beautiful brass and copper piping plus "valves" that aren't at all electronic-back to future eh
I've always believed that story re the Americans laughing about radio valves in a downed Mig Fighter until someone says "Nuclear EMF Pulse". In the savage Nuclear Winter film THREADS [coincidentally also released in the highly significant year of 1984 and about an attack on Britain] the first thing to fail, in the Control Centre under Sheffield Town Hall, is the solid State Radio Equipment!
