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.

OK... That kind of makes sense.....When I get my pod pluged into the working board again (once I've fixed the header) , I'll try to do some homework !!!
eg.... read location 0000 in.... and see if its 16 bits and the pair of 8 bits matches the first bytes of both roms :-)
