In the UK in the 80s IBM had large bill-board adverts that ran along the lines of “…we took UNIX and added a million lines of code …..”.
I always thought (rather unfairly) YES, and every one of them was wrong.

However one of my car registration plates is "AIX OK”.  I changed my mind later on….

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.
