**💻📰 1972 Unix V2 "Beta" Resurrected**
A first-time poster to the TUHS (Thirty Years of Unix History) mailing list announced the successful recreation of a working system from Digital Magnetic Recording (DMR) tapes. These tapes, part of the TUHS archive, contained early versions of the Unix operating system. Specifically, the poster recovered a kernel from a tape labeled "s1" and accompanying distribution files from "s2," representing a version of Unix between Version 1 and Version 2. This kernel predates the previously known earliest machine-readable Unix kernel ("unix-jun72"). The recovered system boasts features differing from "unix-jun72," although specifics are not detailed in this excerpt.
The work involved forensic analysis of the DMR tapes. The poster previously communicated their findings via email to others, who then forwarded parts of the correspondence to the list. The achievement lies in recovering and booting a functional system from these historically significant tapes, providing a glimpse into the early development of Unix. The recovered system represents a critical piece of the Unix historical record.
