Expert System Shell

My HND project was to write an expert system inference engine. The target system was to be a IBM PC, with the code developed in C. However I chose to code all the algorithms first on my BBC Micro in BBC Basic, as that was available at home. When the logic was correct, I translated the code into C for my HND final year project. After passing the HND course, I polished the BBC Micro version and sold it to an educational software house.
