I guess having a big fat guy for A/UX advertisement kind of says how Apple saw UNIX even then.

Jobs were also not that keen into UNIX, around this time NeXT was already going on, and some of the surviving remarks including his presence at USENIX, was similar to Microsoft's tatics, in the sense of bringing UNIX applications and custmers into NeXTSTEP, and then offer them tools unavailable in any other UNIX.

OpenSTEP effort, and collaboration with Sun only started after the sales not going that well as expected.

Nonetheless, I only saw A/UX live in 1994 at Lisbon's IT conference (CEBIT in miniature), and it looked kind of interesting.
