DHC11 seems to be a bit clearer than IDA, it breaks the 6800 instructions
down, and you get the binary setting for the data direction
registers...easier for me to interpret at least...I think it handles
6809, claims to handle the 680X CPUs.<br><br>

<dd>I'm using this to decrypt the 6800 pod ROM so I can figure out the command codes...I hope...but I really am no expert on 6800 assembly (or any assembly - more a hardware sort of guy) so if ANYONE wants to help....I've figured out a bit of it...
<dd>Interesting side note the 6800 ROM also contains the 6502 code...So you might be able to change a 6800 to a 6502, you CAN change a 6502 to be used in a 6800 application, read the 6502 pamphlet and check the schematics<br><br>
