[net.micro.mac] Query: Prolog for the Macintosh

        I recall seeing some queries about Prolog for the Mac, but no real
conclusions or opinions, so I am asking again for a little advise: 
	I have seen ads for the following implementations, and was curious
whether anyone had any experience with one of the them.  Computer Language 
reviewed the OSS Prolog, saying it was friendly but somewhat flawed for 
medium to complex jobs.  Are there any other implementations of note?

    Chalcedony Prolog/m,        $99.95,  La Jolla, CA  619-483-8513
    Personal Prolog, OSS Inc.,  $74.95,  San Jose, CA  408-446-3099
    Advanced AI Systems Prolog, $150,    Mt. View, CA  415-961-1121

In particular, the following considerations are somewhat important:
     1.   It should be a non-trivial subset of Clocksin and Mellish.
     2.   Can one fit a medium-to-large program into a 512K Mac, or
          is more memory a *practical* requirement.
     3.   How good is the user-interface?  In particular, the debugger
          and editor.
     4.   Speed...

Thanks,
