  First I heard of this trick.  Has any other net type folks pulled this off?
  How (well) does it work?  Does the other hardware (custom chips and such) get 
  affected by this hack?  From what I can tell, he is only feeding the 68000
  the new clock rate, is this the case?  If so, how the the rest of the 
  system handle this?  Oh well, enough questions for now!!!

   Any input would be great.  Sounds like a nice cheap means of doubling your
   processor speed.  By the way, how much faster does the thing "actually" 
   go now (i.e. compiles and such)?? 
						See ya all later, Mike...
