For those who might be interested:

Based on a couple of suggestions, I tried to use macutils.  Turns out 
that the last version is circa 1992, c code, no autoconfig file, a make 
file that requires some work.  Found a packaged version for Debian, 
built a virtual machine, installed the package.  Unfortunately, when all 
was said and done, it told me "unrecognized file format."

So I then went into the wonderful world of Mac emulation.  Last time I'd 
looked at things like Sheepshaver, you had to have a retail CD 
containing OS 9, otherwise you were SOL.  This time, I found a 
pre-packaged version that installed and booted just fine - actually, 
just download, unzip, click, and you have OS9 running in a window on a 
modern Mac, with shared files -- way cool.  (For those interested - look 
at 
http://www.macwindows.com/Emulator-for-Mac-OS-9-in-OS-X-updated-for-Mountain-Lion.html 
for download links).

Then I had to dig up a copy of DDExpand - found one at 
http://macgui.com/downloads/?file_id=22663 - had to unstuff it (remember 
stuffit - happen to have a modern copy on my machine), then move the 
unstuffed file to a shared folder (along with the files I wanted to expand).

 From there, it expanded files perfectly.  Of course then I had to use 
Word 2008 to open the resulting files, under Word 2011, I just got blank 
pages.

Thanks,

Miles Fidelman
