I had an e-mail from someone who said:
PDP-11 Sys V is apparently derived from Unix CB 3.0, not from the
normal route... Or so says the great interweb :)
I found a family tree that suggests this. Know anything about this?
I hadn't heard of this before, can anybody substantiate or negate this
assertion, or shed more light on the genealogy od PDP-11 System V?
Thanks, Warren

It contains Features from CB Unix but was not the same thing. In particular shared memory
and semaphores were contributed by Dale’s team but it was PWB 3.0 that was rebranded
system III and then updated and released by USG aka summit eventually as sys V. System
IV was not released outside the bell system I’m not sure if it ever went out inside.
Sent from my PDP-7 Running UNIX V0 expect things to be almost but not quite.

In case people are wondering, I found this
https://www.quora.com/What-is-Unix-and-why-is-it-important which contains a
blue-oval chart that shows it being derived from CB Unix 3. But that the
sources were also different than the ones for VAXen, etc. At least that's
the implication here. Is this chart in error?

@Warner Losh - the picture with the blue balloons is so wrong.... There
are a ton of errors, starting with claiming PWB 1.0 came from Fifth Edition

OK. So I should ignore it then... Thanks for the clarification...

Yep, as we say, it has more holes in it than Sonny Corleone.
