Ok then, is it possible to increase the speed of the A3000 beyond 25 mhz? 
Or, would it be possible to increase the speed of RAM accesses. I am most 
interested in the possibilities of running an 040 at >40 mhz.

One other thing... The chip RAM speed. Does the CPU still access it at 7.14 
mhz, or has chip RAM also been increased to 25 mhz for CPU accesses?
