Can anyone o
Can anyone see a reason why this should not work.
Why not replace the 8 meg 68000 in the ST with a faster 10-16 meg part.
Cut the trace to pin 15 (the 8 meg clock) and replace it with either a 
system generated 16 meg clock ( one goes to the MMU already) or a 
external clock.
This way only the 68000 will be speeded up providing faster cpu operations,
memory accesses will still be at 8 meg so you don't have to replace ram, and
I/O operations will also be at 8 MHz.  - Kinda like the older ibm pc speedups.
