- I don't think this is the case (but I would love to be wrong...). I beleve
- the #clocks each insn takes is more like the 386, then the i486. I know the
- i486 takes 1 cycle to add 2 registers, I think the i386 takes 3, and I think
- the cy486 does also. The cy486 _does_ multiply quite fast 'tho, I think faster
- then the i486.
