The 6808 is a ramless 6802 so the instruction set should be identical. I'm not
sure how they relate to the 6800 and 6809.

Does anyone here know if the 6808 had additional instructions over the 6800. I
know that
the 6809 covers both of them but I can't find any datasheets for the 6808/02. Im
afraid to
use the CPU reference cards by Jon Bowen since they tend to miss some
instructions. I
heard rumors of a bug in the MAME 6808 driver and Im having problems verifying
all the
opcodes.
  thanks, jess
