Squeak is derived from ST-80 release 1, which was shipped to hardware vendors like Apple. The system has evolved gradually over time. There have been a lot of improvements, and a lot of cruft built up too. I don't know of a crib sheet of differences between Squeak and ST-80, but there is a good crib sheet for Squeak, it's called *Terse Guide to Squeak*. It's in the help menu in recent Squeak images, and also here:
