[Simh] Off topic: ULTRIX question

Hi,

If i am honest i think there would be significant advantages to just
running the same OS on all the bits of hardware, NetBSD has a much wider
hardware support base, Alpha, pmax and VAX.

http://wiki.netbsd.org/ports/pmax/
http://wiki.netbsd.org/ports/vax/

Have a look to see if it supports the models you have.

NetBSD also has pretty up to date GCC support,.. but lots of other
compilers as well

I would use GCC 4.9

http://pkgsrc.se/lang/gcc49
https://gcc.gnu.org/onlinedocs/4.9.3/

Which for Fortran supports the old F77 and F95 standards as well as F2003
and F2008

https://gcc.gnu.org/onlinedocs/gcc-4.9.3/gfortran/Fortran-2003-and-2008-status.html#Fortran-2003-and-2008-status

GCC like GEM is split frontend/middle/backend, so the C,C++,Fortran, etc
compilers are quite separate from the targets.

There are Alpha, MIPS and VAX backends, which i guess i implicit as thats
what NetBSD uses to compile the OS.
