Sybase ase installer

i am looking for an installer of Sybase ASE 11.9.2.6 for HP-UX. tried buying from the local distributor but he can only give me the latest version. any idea how i can get a copy?

You can typically buy a license and back-rev the media, did you ask about that?

i’m hesitant to do that since this says only back-rev to 15.x versions are supported.
