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

I wonder whether it will be readable or, more likely, have suffered from print-through from being stored so long. Great find though.

Here's hoping it still reads, after all these years. 🤞

@argv_minus_one @AlisonW @ricci I bet it wouldn’t directly read, but I also think those clever archivists have ways to get the actual magnetic image and compensate for write-through and suchlike!
