Some people claim thar the 6502 is a RISC processor. It's not.

Hill I'll die on: The 6502 is about as unRISCy as a 4500 transistor 8-bit CPU can possibly be. It has over a dozen addressing modes, and is not orthogonal at all.

That says nothing about whether the 6502 is good or bad. In my opinion it was/is quite good for a lot of things, but not necessarily best for everything. It was, however, absolutely brilliant for the time it was introduced (late 1975).
