I had this experience with a Tadpole N40, running AIX 3.

I simply DD'ed the drive, took the image...
$ strings aix-machine.img | grep root:
...to get the password line.

Dump that into a passwd file and run john (the password cracker utility) on
it for a couple days.

I don't think Linux can mount the early AIX filesystems directly.
