Fun fact: The BESM-6 was a Soviet era computer used for a wide variety of tasks, like the processing of the space mission telemetry data of the Apollo-Soyuz test mission in 1975. Between 1968 and 1987 they built 355 of these massive room sized computers. Each had a computing power of 418 kiloflops.
A Rasberry Pi 5 has 24,000x the computing power of all of them combined.
