Naive question:  I've got the opportunity to get a 25 Mhz  M68030
and  M68882  for  a  reasonable  price.  Can I use them in my Mac
accelerator board (a TSI Gemini which allows for just  this  kind
of chip upgrade) but keeping the clock speed at 16 Mhz?  The rea-
son I don't want to change the clock speed is (a) probable incom-
patibility  with  my hard disk and floppy drive and (b) even if I
wanted to I could only boost the board to 20  Mhz  (according  to
the manual).

Thanks in advance for any advice on this.
