Sketchpad

This link was removed and might be dead: Looking Back The TX-2 Computer and Sketchpad http://www.ll.mit.edu/publications/labnotes/LookingBack_19_1.pdf However as the link is a bit obscure, and the failure is a timeout on the URL, I suspect this is just a temporary failure of the link. So I've put it here for good keeping. --duncan.lithgow (talk) 08:29, 19 May 2013 (UTC)
