  Might be a big-endian/little-endian issue. A Z80 (if I recall) would lay
down 16 bit quantities as:

        L0 H0 L1 H1 L2 H2 ...

  while a 6809 (which I know) would lay out 16 bit quantities as:

        H0 L0 H1 L1 H2 L2 ...

  So maybe that's what he's talking about?

  -spc (But in either case, you'll still end up with two files and I would
        think that as long as you know which one you need where ... )
