I'm still having some glitches with my 6800 system and would like to do a proper RAM diag. From reading, it seems like CDAT is the most exhaustive.. but I cannot get it to run. I can load and then run it.. but it immediately fails at address 8000. Since I understand this is used for I/O I am wondering how I would adjust CDAT so it ignores that space and does everything else? Any suggestions would be most appreciated. I think you can alter the addresses with most and least significant bytes but don't understand quite how.
