Preach it, brother!

Yes.

The PDP-8 family has compilers for both FORTRAN II and FORTRAN IV.  16 bits?
What could we possibly do with all that address space? ;-)

FORTRAN.  FORTRAN D (DOS/360), F and G (OS/360), which were FORTRAN IV
compilers (retronamed "Fortran 66").  VAX/VMS Fortran 77, except most VAXen of
the day you seem to be talking about ran BSD Unix and Fortran was handled by
f2c.

I learned FORTRAN IV on an IBM 1401, a decimal computer, before moving on to
PL/1 and COBOL (and FORTRAN) on the System/360.

FORTRAN was, and still is, widespread, even if it doesn't look anything like
itself these days.
