  Forgive me if this is a tremendously stupid question, but...

  I have an old Micronics 386DX-20 motherboard.  Since the
introduction of the 486SX, I can't help but ask if it is possible
to pull my 386 and plug in the SX.  My understanding of the 486SX is
that it is a 486DX w/o the FPU stuff in it.  If this is true,
then it would seem that it is externally functionally equivilent to
a 386DX.  Is there even a prayer that the pins signals are the
same?                        Thanx in advance, Marty
