Just for general information -- someone from Motorola once told me that
the margin for a 68010 is about 20%. He said that if you plan to push it
that far, it's best to use the kind that comes in a ceramic case instead
of bakelite. The reason is that the problems associated with pushing
the clock speed arise from overheating, and the ceramic chips dissipate
heat a little better than the bakelite ones.
I know a few Amiga owners who successfully pushed 12 MHz 68010's to 14 MHz,
so I guess it can really be done.
