Re: vintage F77 compilers for sale

I'd expect 1 and 2 to run on XP, although I don't know where you'll
find an XP machine with a 5 1/4 inch floppy. :-) If you do, though,
they can be set up to run on a floppy-only machine.
You not only need a 5.25" floppy drive (I have one on this XP box)
you also need a DOS boot disk (v3.3 or later, including 7.0 and 7.1)
BECAUSE XP WILL NOT RECOGNIZE SINGLE SIDE FORMATTED DISKS. And
MS Fortran 3.2 was released on single sided disks (probably for
backward compatibility with DOS 1.0 and early PCs with single sided
floppy drives). MS 3.2 was the last version that could target DOS 1.x.
It is also really F77, just that it is Subset F77 (with extensions).

4 won't work under XP. It works under 98 if you set up a shortcut DOS
prompt with the right options, and can work under ME if you use the
shortcut created under 98.
Actually FPS1 can be made to work under XP, it is the included PharLap
386/DOS extenders that have problems under XP. If you have a later
version of 386/DOS or TNT/DOS from PharLap both FPS1 and the EXEs
it generates can be run just fine. Been there, done that.
