Right - either current NetBSD or the Ultrix 4.5 is what I would do. If NetBSD will run
the Ultrix layered products, that would be the system with the most; but I'm not sure
if that will work. Ultrix for instance supports DEC (VMS) FTN - which I know you (Will)
have been messing with. That is the best (most complete) FTN for Vaxen. I believe there
is Ada, PL/1 and maybe even Basic2 and Cobol/RPG [I think most of not all of the VMS
languages for the VAX were released on Ultrix but frankly, I don't remember].
I don’t know if NetBSD has Ultrix binary compatibility on VAX, but it does on MIPS—so much
so that a few years back, someone accidentally pointed their NetBSD boot at the wrong
partition on their DECstation and Ultrix booted right up using the NetBSD kernel!
