I don't mind sharing.  However, there are others that do mind so I
regret to say that right now, I can't.  If the others work out the
issues they have, then I may be able to share.

I have both editions.  The second one is better than the first, and
there's very little in the first that you'd miss in the second.  I
only have both because I've been hacking on mips a long time.

I'll take a look at those...  The first two are most likely silly
forgotten commits.  The last one is a file that was removed.  You can
remove it from the files.mips file.  It was unused by the current mips
code.
