-> this 9005, 9013s, and 9019 stuff. Could someone please explain IBM's

I'll try but I may get part of this wrong.

Vesrion 1.x of AIX refers to that code which will run on a PS/2 or 
on a 370. The latest version in this line is 1.2.

Version 2.x of AIX refers to that code which will run on the RT
series of computers (I don't believe it runs on anything else).

And finally 3.1 load ????? runs on the ne RISC/6000 line from IBM.
The load numbers 89xx (hopefully no one is still using any of these)
and 90xx refer to pre-release loads of AIX version 3.1 with the
xx referring to the week of the year and any letter following 
the xx being a sub revision. Basically you shouldn't have to worry about 
these because if you order now by the time you get delivery there
should be a GA code and all you need to do is order AIX for a 6000.
If you start mentioning load numbers to IBM sales folks they start
looking back at you with a blank face :-).
