You know, it is so far in the past now I cannot recall if "The 6845 was only in the Videx cards" is true or not. I suspect you are right and I am confusing Apple's weird video RAM layout with the 6845. Now I need to go check on my old Apple II.
Update: You are correct. It appears I have reached "that age."
