See https://notes.technologists.com/notes/2017/03/08/lets-start-at-the-very-beginning-801-romp-rtpc-aix-versions/ 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.

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. >> >> >> On Sun, May 1, 2022, 7:46 AM Ron Natalie wrote: >>> >>> Mark Williams Coherent was one I worked with on the PC many years ago. >>> >>>> On May 1, 2022, at 11:34, Andrew Warkentin wrote: >>>> >>>> What was the first "clone" functional Unix (i.e. an OS not derived >>>> from genetic Unix code but highly compatible with genetic Unix)?
