The last release of apple A/UX was 3.1 that came with my AWS95 machine, before that there was A/UX 2.0 for the IIfx and other machines in that era. What I want to know is was A/UX 1.0 ever released and what systems/requirements did it need to run? Until recently there was very little information on A/UX 2.0 on the web and I still havnt seen anything on 1.0 at all (3.0 is well documented). If it does exists its probably 14+ years old.
