The CDC Fortran IV compiler for the 6000/CYBER series (FTN) was written in about 170k lines of Compass. About 5k lines of Fortran IV code implemented part of the debug support.
The compiler was very well written and well commented.
I have zipped up version 4.6 of the Fortran IV compiler source printed out on an emulated CDC CYBER mainframe running NOS 2.8.1 and shared it via Google Drive:
The other 6000/CYBER series Fortran IV compiler called RUN was garbage but it compiled very quickly so it was only used at universities for student jobs. RUN dated back to early versions of the SCOPE operating system which was garbage too.
Enjoy
