What is latest version of AIX PS/2?

Fri Dec 7 00:04:52 AEST 1990

What is the latest version of AIX PS/2 operating system? I have
currently 01.02.0300. I have also a card I can swap for a POSIX
conformance PTF, but I don't know whether it is already in 01.02.0300. 

And yes, this question is also put to local IBM, but no answer, so I
turned to the net.
