A few days ago I had inquired about Fortran/Latex on the DecStations. I received only 1 mail message, and here it is : > > I had a few questions about the Decstation 2100 and DS5000 running Ultrix 4.0 > (RISC) > > (1) is there a public domain version of tex/latex around for these machines? Sure; TeX has been running on the machines since before they were announced.... The UWash distribution should work fine. > > (2) is there a public domain FORTRAN compiler available for these machines? > I looked at the subsets and did not find a fortran compiler for RISC > machines listed there even though there was a VAX fortran compiler > mentioned. No public domain one I know of; we sell a Fortran compiler as a layered product. > > (3) I intend to run NFS and YP on the two machines and since the /usr > file system occupies about 150 MB, and the 2100 and 5000 are binary > compatible, I wondered if there was a ``best'' way of saving space > without causing too many problems later.

The machines are fully binary compatible; different systems were only required for basic machine support before Ultrix 4.0, which supports all machines. We run 5000's, 3100's, 2100's all from the same /usr areas here. Unless you use YP elsewhere, I'd recommend using Bind/Hesiod for name services, though. YP is far from a wonderful name server... Thanks to Jim Gettys for this information. shirish.

I should have responded earlier. I've been using the 'F2C' package available from research.att.com, and then running the results through the C compiler on my DS3100. It's cheaper the DEC fortran, and seemed to barf less often. I've had several programs in which 1.31 fortran died, but f2c -> cc1.31 didn't. In the cases where f2c -> cc1.31 *did* die, running it through 'gcc' gave a correct run, albeit 15% slower. For programs that f77 *did* accept, I didn't see any performance difference between f77 and f2c. MIPS made a good C compiler. As for latex, it's out-of-the-box.
