How hard would it be to revive Eurisko, to the point of understanding how it worked and being able to implement it in modern systems?

I've always been fascinated by what it could accomplish on such limited resources. It seems possible that the tech would be useful even today.

You might want to read “Why AM and Eurisko Appear to Work” before embarking on that project.

If you have the code, an Interlisp system like the revived Medley, and the several papers Lenat authored about the design of Eurisko, it should be “just” a matter of putting the pieces together and figuring out how to get something running.

The file LRR.DRI[AM,DBL] also contains what looks like a REPL log of starting & running it.
