The first 6500 was completely pin compatible with the 6800. Motorola objected, sued MOS and won. So MOS had to change the pin order. I don't know if the names of the pins were involved as well but I can imagine that they changed them as well to be on the sure side. It certainly wouldn't hurt. The hardware manual is from before that episode, as far as I can make out? Segher Message was sent through the cbm-hackers mailing listReceived on 2016-07-26 09:00:22
