The "grey wall" came with VMS Version 5.  I believe that CD distribution 
began somewhere around version 5 also.  Version 5.5-2 or something like 
that would probably be the best choice.  I believe that lots of 
enhancements happened during version 5.???  I might have the old CDs. 
If you cannot find any let me know and I'll see about making a copy.
