VAX/Smalltalk-80?

Just in the middle of getting a fresh OpenVMS install set up on my VAXStation (the original having been done years ago when I barely had any idea what I was doing,) and looking through various repositories for interesting software to put on there, and I got to thinking about something I recalled reading about a few years back. I know from the book "Smalltalk-80: Bits of History, Words of Advice" - http://sdmeta.gforge.inria.fr/FreeBooks/BitsOfHistory/BitsOfHistory.pdf - that, back when, there were two implementations of Smalltalk-80 for VAXen - the first was Unix-based, done by an independent research group, while the second ran under VMS and was actually developed within DEC. This version - VAX/Smalltalk-80 - was headed up by Stoney Ballard and Stephen Shirron; anybody know if there's a surviving copy out there, if it was ever available outside DEC to begin with?
