You need to find out how that machine stores bytes in memory, or on
disk; ask someone familiar with this hardware. Saying "AIX some
version" might not be specific enough - you need to know what
microprocessor is in this machine.

Most likely, this is some kind of Power machine; AFAIK, they are
big-endian.
