It was an incomplete, slow, non-standard OPS5 but was reasonably priced (under $400) and useful for some applications. A later release was supposed to include Rete but the beta version I saw was still pretty buggy. By now though, it might be solid. I reviewed OPS5+ (from Computer * Thought of Plano, Texas, 214-424-3511) on Byte's BIX computer information service in June of 1987. OPS5+ is a very fast, and complete OPS5 for the PC with useful extensions. It interfaces well with external procedures written in C. It is also very expensive (around $1700). You also have the option of running the Common Lisp version of Forgy's OPS5 under a PC Common Lisp, though it'll likely be slower than OPS5+. By the way, anyone looking for a PC-based production system language should seriously consider NASA's CLIPS, available from COSMIC (404-542-3265)for $200. It is program number M87-11021. The documentation is an additional $17. It is written in C and source is provided. I'd be happy to send out copies of the reviews.
