I just received this week a CoCo2B, but instead of have a 74LS785 SAM, it
have an old 6883. The result is an erratic memory behavior with NitrOS-9
crashing when loading, etc.
Anyone has any documentation or datasheet about this newer SAM ? I have
done a quick search on google but found nothing relevant.
