Information about MENUNIX is available in Report AD-A108929 form the government clearinghouse, dated November, 1981, by Gary Perlman. The article is 25 pages long, and is titled: "Two Papers in Cognitive Engineering: The Design of an Interface to a Programming System, and Menunix: A Menu-Based Interface To Unix (User Manual)". This seems to also exist as report 8105, November, 1981, from U of C San Diego. Happy researching!
