For what it's worth, about the only thing a 68010 buys you over a 68000
is that it has a small instruction cache that will speed up very tight
loops. For instance, the 680x0 architecture has no native string
handling instructions, so you have to write a tight loop to, say, copy
the characters of one string to another. The 68010 makes these run quite
a bit faster than on the 68000.
