@itsmemario1 - May I ask why you want a circa 1996 at&t unix variant, rather than a more recent bsd variant? Yeah, sometimes I install old os variants just to tinker with...
Mostly its experimenting with the past and a travel into the past. Just for fun. Though, sometimes I stumble across such retro stuff at work. Im not always in charge, but now and then it helped to have at least heard about very old computer stuff and leads to interesting, nightly conversations.
