I don't know where the fellow got his information, but I was told that AIX
started out as AT&T code, but went through not one but two rewrites.

HOWEVER, when the 1983 transition happened and AIX became a primary site
effort (as discussed in the cited reference), there were those new to
the effort and new to Unix that thought they could redefine behaviors
inappropriately.
For example, I recall one person trying to enforce only one root login
at a time. Larry made it quite clear to that person that we were not
going to violate Unix tradition in that manner.

in terms of rewrites from manuals, while it was
not the first, as I
understand it, AIX was an example of "read the manual, write the
code."
Unlike Coherent, it had lots of cases of things not done quite right.
One standout in my mind was mkdir -p, which would return an error if
the full path existed. oops.
But it was pointed out to me that Condor had all kinds of code to
handle AIX being different from just about everything else.

used it as printer servers for a bunch of inexpensive
Centronics based printers. lpd based server to server transfers. Took the
printing burden off the main systems. Someone came out with a network based
print spooler box (Milan ??) later on which I switched over to after MW
passed into obscurity.
