I just read this thread, so sorry to jump in so late.

The Green Book is often available from Powell's in Portland. THey carry new
and used technical books.

If you don't have a copy you should; it's full of neat papers on the
'early' years of -80.

There is also a quite long paper in the second History of Programming
Languages book from Addison-Wesley on the history of Smalltalk by Alan Kay.
It has examples of -72 as well. This book should still be in print. (1995?)
