A good paper on Chorus:

Apparently Chorus was not "unix" until the SOL team joined them in 1984!
Its nucleus seem very much like a microkernel.
For example there was Bull’s Chorus which I seem
to recall was based on Mach or a competing microkernel (it was a very long time ago and I
used it for no mare than about two hours..).
Close, not quite. Contemporaries but
not the same.
Chorus was a C++ rewrite of Gien's Pascal based 'SOL' systems [Gien M.
(1983). “The SOL Operating System”, USENIX Association, 1983, Proceedings of the Summer
‘83 USENIX Conference, Toronto, Canada, July, 1983, Pages 75-78.]
