Squeak still has the old MVC interface if one wants to use it.

Playing around with it for a few minutes not everything works.  For
example trying to open a change sorter gives a traceback.

I'd stick with Morphic either on Cuis or Squeak.  Though Cuis will be
further from the BlueBook it has the advantage of being smaller and
cleaner.  It's probably easier to learn with that.

The other thing to think about is the idea that you learn Smalltalk
from a book is probably the wrong way to go about it.  Unlike lots of
other languages Smalltalk is meant to be discoverable from within the
system. You learn it by exploring.  

At first that can be slow as you figure out what magic word you need
to search for.  But rather quickly it becomes easier and easier to
find stuff.
