Hmmm..  You won't get too far on a IIvx...  Hopefully soon, though.  We
made a few assumptions in our original port that turned out to be invalid.
A couple of these have prevented otherwise usable systems (like the ci/si
and probably the vx and friends) from working.  These are largely based
on the migration of MacOS to using the MMU...  *Sigh*  In the next few
weeks, we hope to get clear of that problem and get on to more interesting
device drivers, etc.

Actually, I'd surmise that for the IIvx, the hardware address are similar,
but that the memory map for RAM is not what we expect.  This is just a guess,
though, largely because I don't want to try to find out right now.  It looks
like we'll be able to get our hands on a IIci for a little while, so it might
be useful for you to see how different the IIvx is from the IIci.

Thanks for your interest!  I hope that you'll get a chance to run it
