We ran a version of Berkley Unix on our VAX 11-780’s back in the day.
Litigating with IBM is never a good idea. The Justice department learned that years ago (after litigating from 1969 - 1982.) It appears that patent trolls haven’t figured it out yet. (Although SCO eventually found out the hard way).

I no longer do software, so I can’t verify usefulness.
Wait, I thought the late Jimi Hendrix started Project Monterey, and Eric Burdon wrote a song about it...
