	Of course you realize that these speeds _can_ be greatly improved
upon.  Generic benchmarks are really annoying, you know?  The best bench-
mark, in my opinion, would take the best possible speeds for each machine.
And it's not like you have to roll up your sleeves and hijack the FPC either.
Some guy I know wrote his own benchmark doing exactly the above, but
with a 32K buffer, and the time went down to somewhere in between the Mac
Plus and the Amiga.
