Who's next? HP, SGI, Sun? They've all benefitted/contributed to/
from Linux. SCO'll be claiming next that
OpenOffice was derived from 'ed'!! Heck, There's probably
some Linux code in OpenServer and UnixWare! This could
get very circuitous. I wonder if M$ paid off SCO
for UNIX services for WinXX? Anyway, I thought that AIX was derived
from Mach (OSF) and that Mach was derived from BSD.
(it's been too long... I've forgotten all that stuff now.(
although, what I remember of early AIX is that it was
very ATT system V, Release III like (my mind is going...
got to get (my body)out of here!)))
Just say NO to SCO!!

AIX genesis

There are (or were) more than one "AIX" source bases... In 84-86 I
worked at IBM on the first one. It was an IBM-enhanced port by
Interactive Systems Corporation of ATT System V to a virtual machine
(VRM) on the RT PC. That would be the original System V,
sometimes referred to as release zero, back when the man pages
were a still a single volume - Jan 1983 is the date on mine. SVR2
stuff got pulled in later.

By the way the RT PC had little in common with an Intel PC: just that
there was an 80286 coprocessor option, and it had PC compatible 8
and 16 bit I/O slots... beyond that it was simply the first RISC ala IBM
architecture out the door - a single chip big endian commercialization
of IBM Research's "801".
