Decimal machines, such as the 1620 and 1401?  Of course, these aren't
word-oriented machines either, but variable-length systems.   Conversion
between either of those and your VAX is not simply a matter of
byte-swapping.

Or how about architectures not using a word length that's an integral
number of bytes?
