Hi, Research Unix Editions 8, 9, and 10 will no longer have copyright asserted over them. https://www.spinellis.gr/cgi-bin/comment.pl?date=20170328 says they contain, amongst other things, "graphics typesetting tools" so perhaps there's something of interest to today's troff users in them. Cheers, Ralph.
