Since the parallel IO port is out on

Yeah, I know, but the numbers still look good anyway. I think
that's a good equation - take "anything", divide it by Win98,
and realize a 15:1 slowdown.
Next go around, DOS will cease to exist anyways, and Roman
will have to retire. Me, I'm moving to the Palm - just think
of it like the PC before Windows.
