The System V kernel was never designed to be a production kernel. It was
designed to provide a level of function from an R&D organization. AT&T sold
binary licenses for $60 for 2 users and $250 for unlimited users, whether you
bought it direclty from AT&T or bought it from a comapny which had a source
license ($100,000).
Circa 1990, there were at least 5 companies I knew of that had a source
license and sold "improved" versions of System V, with the improvments
being in performance. Most of that in device drivers.
I didn't even know that AT&T had a version of their own until 2 or 3 years
later when I was offered a copy of it complete with a PC emulator so you
could run mmultiple MS/DOS sessions.
I can only remember three of them, Everex (ESIX), Interactive (which later
became Solaris via a stay in Rochester), and SCO (the real one), but I'm
sure there were others. Not counting SGI, DEC, HP, Apple all of which sold
a version of System V.
I'm not counting SUN because AFIK, they did not buy a license from AT&T,
they bought a company which had a license.
