A tape-based piece of unique Unix history may have been lying quietly in storage at the University of Utah for 50+ years. The question is whether researchers will be able to take this piece of middle-aged media and rewind it back to the 1970s to get the data off.

The news was posted to Mastodon by Professor Robert Ricci of the University of Utah's Kahlert School of Computing.

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

The nine-track tape reel bears a handwritten label reading:

UNIX Original From Bell Labs V4 (See Manual for format)
