One reaason why you don't hear much about that is because the first
version of Microsoft Fortran for the PC wasn't real great.
It was written in Microsoft Pascal.

How does this connect to Microsoft's FORTRAN-80 for CP/M circa 1977?
unrelated product, with no apparent connections, that I'm aware of. The
8080/Z80 FORTRAN-80 would have been a better starting point!
Bob Wallace wrote the original Microsoft Pascal; I don't know who wrote
the [PC] Fortran, other than being told that it was written in
Microsoft Pascal, and to avoid the run-time library.

I did some reverse-engineering of the Microsoft FORTRAN-80 compiler, and it
appears to be hand-written in 8080 assembly.
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.
Exactly.
Microsoft Fortran for the PC, written in Pascal, was not related to
Microsoft FORTRAN-80 for CP/M, which was written in 8080 assembly.
Microsoft Fortran for the PC was not related to Microsoft FORTRAN-80 for
TRS80, which was a derivative of Microsoft FORTRAN-80 for CP/M, which was
written in 8080 assembly. Because the TRS80 was Z80, I would not be
surprised if some of the TRS80 specific code in Microsoft FORTRAN-80
for TRS80 might have used some Z80.
Microsoft Fortran for the PC was written in Pascal.
It was an unrelated product.
I don't think that any of the Microsoft Fortran products were related to
the Intel FORTRAN-80. Did Microsoft ever develop anything in PL/M?
Did Microsoft ever develop anything for ISIS-II?
