Yes, but need some modifications.

The picture is my test memo, based on information from Hans' site.

I went to Hans' web site to take a look. My goodness, I guess it's been awhile. Much more info' there since the last time I visited. Still haven't found the modification you show but I will keep looking.

Thank you.

Cheerful regards, Mike

Not all 65C02's are the same.

The short answer: yes, but see Liu's notes.
