Actually, I think that I looked at some benchmarks that had the MacII faster
than the LC in interger operations as well. I wasn't suprised since the LC only
has a 16bit data bus. Personally I think it is a shame to tie a 020 down to a
16 bit data path.  I wonder how much money (on a per unit base) apple saved by
doing this?  Anyone know?

  One more question, does anyone know why the FX's PDS runs at 20MHZ? Is it due
 to the fact that the 030 spilts it clock in half, thus making the efective
 speed of the bus 20Mhz. I guess my real question is if the PDS is a
asynchronous or synchronous bus. Since you already have the Nubus, why not have
the PDS run at the speed of the main cpu?

   Please E-mail, unless you think that someone else might be interested in
   knowing.


   Later,
