I was informed yesterday you can also load the file using the pull out side menu on the Medly VM as well as the desktop "IMPORT/EXPORT" button on the desktop. Just another option to load the file into the VM's filesystem. Following that, the usual Right Click desktop EXEC -> Interlisp shell followed by (LOAD "RING.LISP") followed by (HUNGARIAN.RINGS) in the InterLisp EXEC window. :)
