**M????          Genie, Quad Pentium  [no datasheet, some info]    c95
***Notes:
It looks  like this  was never released,  very little info,  the 4-CPU
support   of  the  Pentium   is  inconsistent   with  the   Intel  SMP
architecture.

"
3) The Genie Chipset (Acer Labs: 10B9/4281) (8/27/95)
This is  a chipset by Acer  Laboratories Inc. (ALI)  which is intended
for  use in  multiprocessing systems.  Specifically, the  chipset will
support up to four P54C, P55C, Cyrix M1 or AMD K5 processors, though I
don't  know if  you  can "mix  and  match" the  CPUs  (though I  doubt
it). I've had  no reports of success or failure  with boards which use
this chipset.  "
