AU/X for PowerPC would have given them a contender
AU/X was a pretty awful Unix cobbled together to meet a narrow market need
unrelated to the markets Copeland was intended to address. It's singular
grace was it let Apple say with a straight face "yes, you can run Unix on
our hardware" (and to a lesser extent, say "and see, it looks pretty like a
Mac"). It wasn't a contender in the Unix market, much less the "platform
to take Apple to the next level" market.
