The source for Doug Lenat's legendary EURISKO program has at long last been found and can now be run using Medley Interlisp.
Install Medley Interlisp
Open an Interlisp Exec by hold right-clicking on the background and releasing on "Interlisp" in the EXEC sub-menu.
Change to the directory where you downloaded EURISKO
cd /home/foo/EURISKO/
It is recommended to disable the Medley feature that asks to continue after a full page of text has been output. (This is reset on window resize)
