More Smalltalk
I just spotted another Smalltalk implementation:
ChocoSmallTalk is a hybrid SmallTalk/Lisp implementation in Common Lisp. The purpose of this project is an embedded SmallTalk in Lisp, known as a meta-circular implementation of lisp as an add-on. As time permits this project should be usable on ARM based processors on handhelds to make a real lisp-smalltalk machine.
