I'm originally from AZ but we moved away when I was 3. I did go to college there, though.
6809??? That was the very processor in the TRS-80 Cocos! The more I think, yes, that is far more likely to be the CC on a 6809.
I work with embedded stuff too. My old workplace used 68000s as their bread-and-butter processor and I used assembly code, because there was less than half a K of ram (lol). Now I do embedded C using Nucleus operating system.
Nice to see another 50+ year old on here.
I like your avatar. Is that a CC register from a 6800 or a 6809 8-bit processor?
I work with embedded programming. I used to have a TRS-80 Color Computer as a kid.
