I was at Middlesex Poly in the late 80s / early 90s doing an AI degree. I'm pretty sure one of the things we used was the EXSYS expert system shell running on VAX/VMS (because that's where I first came across the name). We didn't use it much though because the AI group had a bunch of early Macs that everyone preferred.
