I'll just  have to start all of them and see which have the fullest
set of compilers.  :-)  Maybe have to find a version of emacs that
is publicly available that will build on Primos.  :-)

I wonder if anyone has a copy of the sources for EDV?  that was our
common editor when I did this for a living.  It was a very good full
screen editor and was written in Fortran (with calls to some low
level Primos stuff for the single character input and such).

Ah...  Sources.  That was my ballywick back in those days.  Maintaining
the OS and layered products for a cluster of 850's at West Point.  Those
were the days.

I barely touched 20 saw nothing beyond that.

Well, I guess I don't need to go looking in the attic then. :-)
I think I was the only one who took the class that actually kept the
manual, which is how I ended out with more than one copy.  :-)

I would say that the biggest help other than compilers would be EMACS. I
may actually still have the Prime EMACS Manual.  I think I kept that
because I use EMACS on other systems, too and it was a good manual.

Thank you.  That stuck in my head but reading the pocket guides I still
have didn't refresh it for me.
