I don't know what VAX hardware VMS 1.5 supported, what VAX hardware
that Simh supports, or what the overlap is between the two.

There's a reasonable chance that someone will chime in with experience.



You are limited to what the VAX-11/780 system had for peripherals and
typically under 8MB ram (it maxed at 16mb).
Well, for command-line computing (well, this IS the classic computing list) you can do a lot. Our first 11/780 had half a megabyte of memory. Friday afternoon one memory board went bad, and I pulled it out. A user group ran a gigantic batch job of mechanical analysis over the weekend on 256 K! I was amazed, I really thought it would thrash itself to death on that.

I ran a microVAX-II at home on one meg for years.

But, I never experienced VMS before about version 3.4, I think. I'd really hate to run any VMS that didn't have loadable device drivers. Doing the brute force sysgens was so RSX-11 ish. I think VMS 1.5 still had a bunch of utilities running in PDP-11 emulation.
