Oops, I forgot about that. You're right; the 68010 saves slightly more
state on the stack than the early 68000. I have a feeling that was fixed
in later 68000; some traps save more state than others.
You can't get 68010s any more, unless you can find old stock somewhere :-(
You can still get 68000s and 68020s.
