The RSX-11 AME still runs on OpenVMS-VAX V7.3 (or whatever the official
name is.) As does ROSS/V (RSTS/E emulation). I don't know if you can
get support for VAX-11/RSX, since Mentec seems to have crawled into the
woodwork. We no longer have any supported ROSS/V customers, but offer
me enough $$$$$$$$$$$$$$$$$$$$. :-)
However the oldest RSX executables are from the early 1970s.
RSTS/E .BAC files from V6A (1974?) should still run. I don't remember
if anyone has ever tried anything older than that. Same with mid-70's
RT11 executables that ran under real RSTS/E back then. I'm not sure
when the original PIP.SAV was released, maybe with V6B (early 1976),
but it should still work on ROSS/V on VAXes unless it has Y2K problems.
