The program that did this was called "23fix" (since it "fixed" things so that they could be run on a non split i&d 11/23) > Robert Tillyard asked "Would SCO->Caldera have copies of this [PDP/11 > XENIX]?"

Unfortunately all of the "official" SCO archives from this era went into some offsite storage facility about 10 years ago, never to be seen again. I expect that there are still a few copies around, but I don't personally have one. By the way, just to complicate things even more, SCO really didn't do much at all with XENIX/11 since they already had their own V7 based UNIX, called "Dynix" (a name which was later sold to Sequent). Most of the actual XENIX/11 systems that I encountered were actually supplied by the "Software Products Group" of Logica (which was ultimately acquired by SCO back in 1986)
