Somebody here at our local Amiga Developper Forum in Toronto did a hack
like this. He uses a 16MHz clock, but as far as i understand, he has to
switch it back (at the right time) to 8MHz to access the chip memory and
the coprocessors. This switching is done on the fly, it seems to work, he
has a nice little green/red light on the front of the machine which changes
color when the processor changes speed.
It seems MUCH more complicated than just connecting the clock pin of the
68000 to a faster clock.
The name of the guy is Earl Pottinger.
He has done a few other hardware hacks like an el cheapo memory expansion
made by stacking the memory chips and soldering their pins together....
it seems to work...
