Does anybody know where to get a public domain OPS5 (source or objectcode) 
running on IBM-PCs - maybe on the net?
There should 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.
It  seems to  be common for the people who advert PC-OPS5s not to make any 
comment about inclusion  of the Rete-Match. They only make proposals like:
 
" Our implementation is so  efficient that you'll think your PC is a full-
  sized mini-computer."
 
There are even some "full implementations" which do not use Rete-Match!
Has anybody had any experience with
 
- Sierra OPS5 by Inference Engine Technologies
- 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.
