Hello

I am currently looking for some resource that would show how the internal control logic works on 6502 on the hardware level.
I am interested in by-cycle breakdown, (ex. what control lines are actuated on each stage of the instruction, what happens on clock transition high and low <- this is very important part, etc.)

Would appreciate any helpful resource on the topic.

I'd always go first to visual6502, for example
http://visual6502.org/JSSim/expert.html ... ,DPControl

I'm not sure if you'll be most interested in plaOutputs or DPControl.

If you prefer a C program, try Perfect6502 which is the same data and the same algorithm
