In at least the more recent versions, Intel FORTRAN-80 on ISIS-II was

The ISIS-II PL/M compiler was bootstrapped from the PL/M cross-compiler
that was written in FORTRAN, and it's entirely possible that early versions
of Intel FORTRAN-80 were developed that way as well.
On the other hand, Intel also had a FORTRAN-80 product, which was
unrelated
to Microsoft FORTRAN-80. Intel FOTRAN-80 ran on
their MDS development
systems under the ISIS-II operating system, and the compiler was written
in
PL/M.
Which is even funnier when you realize that the PL/M compiler
was written in Fortran.
