Does anybody know where to get a public domain OPS5 (source or objectcode) 
running on IBM-PCs - maybe on the net?
There ought to be an unmaintained Common-Lisp version which I think could be
ported to GCL or XLISP. Performance is not the main point although the es-
sentials (RETE-Match) should be included.
As far as "professional" (expensive!) versions are concerned:
It  seems to  be common for the people who advert PC-OPS5s not to make any 
comment about inclusion  of the Rete-Match. 
 
There are even some "full implementations" which do not use Rete-Match!
Has anybody had any experience with
 
- Sierra OPS5 
- OPS5+
- TOPSI 2.0
 
Are these programs full implementations (given VAX-OPS5 as kind of reference)?
I would be very thankful for every comment on the topics mentioned above.
