It has been illuminating, surprising, but not shocking, the last week of so,
to learn from from posts here, that AIX/370 was hard to get and mostly a
university offering. What we (AIX people associated with RT/PC and then
RS/6000) were told was that "everybody", especially Federal customers,
wanted what became known as TCF (the original Locus work) for 370 and PS/2.
I remember one Federal Systems Division person who seemed especially
effective as a Locus advocate. I'd always assumed AIX/370 and AIX PS/2
became more available than reported here, but I left IBM before they were
released.
Enumerating factions/companies, just regarding AIX & Unix, there were the
Federal Systems faction/company, the academic factions/company (primarily
two factions, BSD & TCF, in Palo Alto), the PS/2 faction/company, the
Rochester System/38->AS/400 faction/company, the Austin development lab,
several Research locations (primarily Yorktown), ...
There was also AOS (Academic Operating System) which was basically
repackaged BSD 4.x ported to the IBM/RT PC[1]. At MIT's Project
Athena, most people massively preferred it to AIX, but we were force
marched to AIX by 1987 or 1988. :-/
