Simh is rather nice.  It's long been my go-to for PDP11 and VAX
emulation.  Hacking on it about 15 years ago to have better battery
performance (mostly spinlock-hunting) on OS X was fun, too.  It tends to
feel very "abstract," though, because every machine goes through the
same interface.

Most of what made, for example, using Hercules not feel like just
running another VM is that so much of the console experience is
preserved (albeit at some necessity because of how IBM mainframes treat
the consoles as extra-special).  I guess I was hoping for something less
like simh and more like Hecules.
