6th edition had fc <http://man.cat-v.org/unix-6th/1/fc> but it would not
take a standard F4 (or F2) deck to my knowledge. It may have been in 5th
also. It was pretty limited. As I said, I remember one of the arguments
for why not UNIX in the EE Dept was the lack of a 'proper' Fortran
implementation.
I remember an an early attempt at f2c in those days [which I think came
from UMich], but it did not work much better than fc itself as it was a
subset language. FYI: f2c was much later (I want to say 82-83ish and post
f77). But it was what Ted and I used to start to convert advent to C for
the UNIX, so that was pre V7 and must have been 76ish.

VAX/VMS Fortran was under development at the same time as the
Fortran-77 standard. For the VMS Fortran development team, the new
F77 features weren't a particularly high priority at the time because
there wasn't any existing code that used them, whereas there was a ton
of dusty-deck IBM FORTRAN II and FORTRAN IV code out there, especially
in the educational market DEC was keenest to sell the VAX into. F77
features were implemented over time in VAX/VMS Fortran, and after a
couple of releases it was fully Fortran-77 compliant. But at first
release in 1978 it was an extended subset of F77.
Was f77 the first Fortran for UNIX, or were there other compilers for
Fortran before f77 came along?
