yes, where to ?

With respect to your first question, I subscribe to MWJ and, after a
modest amount of looking on the web, find that the MWJ archives seem to
go back only as far as 2002. I was unable to locate a copy of the 1988
paper elsewhere on the web, which seems strange. Perhaps someone out
there has a paper copy and can scan it. I would also imagine that a
paper copy could be located in some university library.
But then, you have probably already been down those same paths.
