This is hosted on the website of Mary S. Van Deusen, who seems to be the editor of the Journal where this article was published in.
I really recommend looking at the other parts of her website[1], especially if you're interested in the history of computer science / programming [2].
Her YouTube Channel also contains interesting Videos [3].
I'm too young and did not live at that time, but I'm happy that she preserves these materials.<p>[1] <a href="http://www.iment.com/maida/" rel="nofollow">http://www.iment.com/maida/</a><p>[2] <a href="http://www.iment.com/maida/map/computers.htm" rel="nofollow">http://www.iment.com/maida/map/computers.htm</a><p>[3] <a href="https://www.youtube.com/watch?v=VvU3pJbZBj0" rel="nofollow">https://www.youtube.com/watch?v=VvU3pJbZBj0</a>
