Please keep in mind that the high fp score came from Digital's
Alphastation 500/500 which starts at $26,000 for a base system. The
clone makers charge about $3,500 for their base systems.  Concerning
this matter, here's a recent posting from the axp/Linux list:

Perhaps the difference in performance between Digital's systems and the
clones using the same CPU will diminish when better motherboards are
introduced.
