There was an internet in the time around RotJ and they had a newsgroup which was used to discuss the movie. Google Groups used to have an archive of the discussion, but i'm having difficulty finding the info... Can't remember if it was R.A.S.S.M. or another group name...
Edit:
Google Groups Advanced Search you can select the years to search through, the archive starts in 1981, so put in whatever query you want and there are a bunch of sw discussions back then
