The Mini #CommonLISP I have been working on now runs on CP/M with 2416 free cons cells. Enough to load Ken Kahn's tiny PROLOG and run a few simple queries.
The #AgonLight (18MHz eZ80) loads the LISP part of the code (236 lines) in 11 seconds. Simple programs run at acceptable speed, but slightly more complex PROLOG queries take minutes. 😊
