Here's a look at "the world's largest supercomputer" in the socialist utopian future predicted by a 1960 East German science fiction film
The movie is "Der Schweigende Stern," released in the west as "First Spaceship on Venus."
Like other Soviet-bloc films, it forecast a utopian future in which socialist scientific advancement led the world.
In this scene, the scientists are using the supercomputer to decipher an alien message recorded on a device ejected from an alien spacecraft before it crashed.
The movie is full of pretty cool high-concept SF stuff that you didn't see coming from the West in those years.
