It would be nice if we could speed up the UNIX PC but its custom MMU and unknown software incompatabilities probably rules out a 68020 daughter board. Just recently, however, products have been coming out for the Amiga which put a higher speed (14Mhz) 68000 on a daughterboard which matches the processor to bus speeds when accessing the system bus. Apparently, there is a similar product for the Macintosh which incorporates an on board cache. I wonder if there are any high speed versions of the 68010 available and if it would work if substituted for the 68000 in the daughterboard for the Mac. A 16Mhz or so 68010 with a write through cache should work just ducky. I don't hold out high hopes, however, as Motorola hasn't shown signs of speeding up their down line processors and I'm not even sure these sped up 68000s are Motorola parts not some knock-off. Food for thought. Maybe someone more in touch with the current state of availability for 68000 style processors can educate. David Albrecht
