This one is great:
http://users.ipa.net/~dwighth/smalltalk/St76/Smalltalk76ProgrammingSystem.html
but doesn't mention meta-classes. On page 34 of Alan Kay's "The Early
History of Smalltalk" paper there is a drawing labeled "Smalltalk-76
Metaphysics". All classes were instances of the class Class object,
which was a subclass of the class Object. Little Smalltalk initially
had the same design (which makes all classes have the exact same set of
class methods) but has moved to a more Smalltalk-80-like system in
version 4.
There is a simulation in Squeak of Smalltalk-72, not 76.
