It's a long time since I've run v2, but the rest all run on my 11/73 as far as I remember.  It may depend on the exact config (SYSGEN) but it certainly won't work unless you have exactly the right boot block on the media.

V2 doesn't have sysgen.  But yes, the boot block is device specific (at least in the early versions, I don't have experience with the later ones).  You can use PIP to write a boot block of your choosing.
