Wasn't a lot of Voyager's code written in C?

It was being built before or just shortly around the time that C was being made.

Per sources found on Hacker News:

"The spacecrafts’ original control and analysis software was written in Fortran 5 (later ported to Fortran 77). Some of the software is still in Fortran, though other pieces have now been ported to the somewhat more modern C."

There's good discussion about it here also that may indicate that this is the ground software and was written in Fortran V, not Fortran 5. To my mind though, C was still far too new at the time for it to be the smart choice here, and I'd assume custom assembly along the lines of what was needed for the AGC is needed here.

TIL. I thought C was older than that.
