Here's a link: http://www.spies.com/~aek/alto/index.html On a page: http://www.spies.com/~aek/orphanage.html that links to the first, link, the author implies he's got a work-in-progress emulator started. He has some docs also. What I don't think exists anymore is a readable pack containing Smalltalk-72, Smalltalk-74, or Smalltalk-76. Supposedly, Smalltalk-78 was implemented only on the portable Notetaker. Smalltalk-80 would most likely have been implemented for the Alto, but by then, much faster Xerox workstations were available, and people stuck on Altos would have thought of themselves as second-class citizens. Archives do exist of Smalltalk-80; however, they are largely unavailable. Fortunately, Alan Kay, Dan Ingalls, and others who created ST80 at PARC have duplicated the effort now that they work for Disney. The revamped ST80 is called Squeak, and you can download a version of Squeak for almost every platform. For more information on Squeak, check out this link: http://squeak.cs.uiuc.edu/ Regards, -doug q
