Yes, but maybe the forced march at Athena was a year or so later, ’88 or ’89?? There was a preceding IBM internal “forced march” involving Bruce Walker from LCC, people from Palo Alto responsible for AOS (two co-authors of https://technologists.com/sauer/Convergence_of_AIX_and_4.3BSD.pdf <https://technologists.com/sauer/Convergence_of_AIX_and_4.3BSD.pdf> plus a couple of others) and AIX people. The work in that 1989 Uniforum paper was done in 1988, targeting AIX 3, as discussed a little more in https://notes.technologists.com/notes/2017/03/08/lets-start-at-the-very-beginning-801-romp-rtpc-aix-versions/ <https://notes.technologists.com/notes/2017/03/08/lets-start-at-the-very-beginning-801-romp-rtpc-aix-versions/>. 

When I left IBM at the beginning of May 1989, I was running AOS on my home RT and AIX 2.2 on my office machine.
