   That's too bad...

   Well, by this definition, I would suppose that every micro-programmed CPU
is considered RISC, as microcode only has a limitied amount of instructions.
What makes a CPU a RISCy one, in my mind, is one where the _user_ has few
instructions, and instead of micro-coded, it's hardwired.
