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.
