IBM architecture - RT
IBM architecture - RS/6000
IBM architecture - S/370
Intel architecture - i386

(rumors of)
Intel architecture - i860	(Wizard PS/2 cardset with 4xi860)
whatever comes out of Steve Chen's supercomputer work

Of course, with IBM not licensing AIX source to anyone, these are only
IBM machines, but that is not the same as AIX being a non-portable OS.

Rumors are that IBM's customers are pressing very hard for source
licenses and that someday such licenses will be available.  Whether
that would lead to ports to other machines, I can't predict.
