Need info on SysV/AT f77 compiler

[leein at uicsrd.csrd.uiuc.edu]

Hi, there!

Has anyone used Microport Sys5/AT for FORTRAN program developments?
Is it relaible?
I heard that f77 compiler comes with Sys5/AT Software Development Package
for 286 machines.
What company's f77 is that?  Green Hill's?  (386 f77 is Green Hill's)
Is it dependable?

   Thank you in advance for any kind of information.
