One of the arguments for RISC is that the 6502 has over 200 registers, all
conveniently located on the direct (zero) page of memory.
.. And one of the arguments against its RISC nature is that the
instructions all take varying numbers of cycles to execute, whereas a RISC
processor typically has all instructions set to a certain number of cycles.
