[OFFER] AT&T UNIX System V Release 4.0 Version 3.0
I found this really obscure version of SysV here: https://archive.org/details/svr4-v3.7z. To be percise, I rebuilt it from the source code. (For now, it only contains the install media for a very basic system, with no add-ons, but I am trying to find a way to build all of the add-ons from the original sources)
