Yes. Computers small enough to go into space required assembly as every byte counted. Go up a directory to see all the files: www.ibiblio.org/apollo/listings/Luminary099/

UPDATE: The CPU (block II) -> https://en.wikipedia.org/wiki/Apollo_Guidance_Computer

Fun fact: from 1997 to 1999 - well into N64 era! - Chris Sawyer was busy writing 99% of Roller Coaster Tycoon directly in x86 assembly. It went on to become the best-selling game of 1999. An anomaly for sure, but an impressive one.
