Did anyone use FORTRAN?  I do remember IBM wrote the OS/360 FORTRAN (H) compiler in FORTRAN.


PRIMOS, the OS used by Prime Computers was partially written in FORTRAN, at least in early versions.  I think they migrated to something else later.

Although I didn't work with the machines myself, I remember seeing my colleagues digging in FORTRAN code chasing system problems.

Primos was a conglomerate of a number of languages.  Not including
C.
