        But whhhat about all those old, old Suns, the ones without back to
        back capacity. What about the tens of thousands of NI5010's or
        3C501's. People bought them, have them, are working with them
        daily even though no double buffering is available. Its not just
        a querstion of being a lowball vendor, reality is the fact that
        old outmode hardware is out there and used! Software must be
        cognizent that it will not always run in ideal situations. In
        fact, I define good softwarre as that which can perform adaquately
        under less than ideal environmental situations.
