I'm following Ben Eaters videos too, they are very good.
My first exposure to a 6502 was a KIM-1,
at the university, which was brand new at the time.
I still have the parts of the Apple II+ (only lost the case) but they are not assembled,
and probably need some restoration.
This is another channel that I can recommend:
This guy is running a hardware turing machine to emulate a 6502 system running packman.
