While cleaning a storage room, our staff found this tape containing #UNIX v4 from Bell Labs, circa 1973
Apparently no other complete copies are known to exist: https://gunkies.org/wiki/UNIX_Fourth_Edition
We have arranged to deliver it to the Computer History Museum

Magnetic tape can last multiple decades. There’s no telling whether THIS magnetic tape lasted that long, but the medium is pretty hardy.
Keep 'em in a salt mine.
