If a 68000 system uses 8 bit roms then they will be interleaved in the
memory map, hence generating the rom signature for just the 8 bit rom on
it's own is not going to match.
I guess it either uses a different algorithm, or you need to interleave
the two roms, and generate the checksum for the new double sided rom.
biggest pain I found with the Fluke pod is that you can only do 16 bit
read/writes - I had some hardware that had a custom chip that processed
32 bit writes, so had to 'poke' some machine code in to ram and call
that to do the job.
