Can someone shed some light on the compatibility (or otherwise) between the various versions of AIX - in particular is it true that AIX 370 is 1.2 - the same 1.2 as AIX PS/2 1.2? I know there are big differences between these and AIX V3, but I wasn't aware that the others had converged yet. Cheers -- Lindsay A.

The compatibility between AIX 370 1.2 and AIX PS/2 1.2 is very, very good. Why? Because they are built from the same source tree. Virtually every program (including the kernel) comes from the exact same place. Notable exceptions are the compiler (and related components) and some very specific 386 or 370 tools (DOS merge on 386en only and VM/CMS interaction tools for the 370). Hope that clarifies things. BTW, the same holds true for AIX 1.2.1.

AIX/370 and AIX PS/2 are both at V1.2. With the exception of relatively few files the kernels and applications for the 2 platforms are built from the same source. You should find few incompatibilities between these systems (unless, of course, you start talking about things like hardware support and interaction with VM). The RISC 6000 runs V3. The V1.2 and V3 architects have worked together to try to maintain compatibility across the family. Despite the numbering, V3 is not a superset of V1.2. Each platform has unique features. The systems have been converging, and despite the differences the various platforms are more like each other than are most other pairs of machines running flavors of the Unix OS.
