All Macintosh Prologs should run fine on any PowerMac (under 68K 
emulation, if not natively).

LPA MacProlog32 runs great on PowerMacs, but only under emulation.  With 
serious processing (i.e., minimal disk and screen I/O), a stand-alone 
MacProlog32 executable that ran in nearly seven minutes on a Quadra 800 
(25MHz 68040) ran unmodified with the same data on a PowerMac 8500 
(120MHz PPC604) in about 1.5 minutes.  This was with language processing;
numeric computation has even greater speed up.

I believe LPA is considering releasing a PPC native Prolog compiler.  
If you are interested, please let them know.  (I have at least once!)

Also, ALS Prolog is available on 68K Macs, and also available on
IBM PPC machines running AIX (with native compilation).  Perhaps ALS
could also be persuaded to port their native PPC compiler to the MacOS.

See the Prolog FAQ for other Macintosh Prologs.
