I've used a few later versions of rule-based tools like https://www.cambridge.org/core/journals/knowledge-engineering-review/article/comparative-evaluation-of-three-expert-system-development-tools-kee-knowledge-craft-art/008CC6CCEE4436E18688B26647753423 https://www.cambridge.org/core/journals/knowledge-engineerin... but never got to try the original Lisp ones.
