Thank you. It's a big article, it starts on the page 90 and ends on 147(!) there. Also, the article is from 1981 and Tesler already works for Apple, as seen on the first page.

To compare with the article date, Apple Lisa was released January 19, 1983 (and, by the way, Macintosh January 1984, iPhone January 2007, iPad January 2010 -- Jobs certainly had a system).
