As well you should. I am honestly curious (for my own satisfaction) as
to what the natsemi docs say the delay code should do (can't imagine
they say "use io port 80 because it is unused"). I don't have any
copies anymore. But mere curiosity on my part is not worth spending a
lot of time on - I know you are super busy. If there's a copy online
at a URL ...

I agree that the problems of chip logic and ISA delay are all tangled
up, probably more than need be. I hope that the solution turns out to
simplify matters, and hopefully to document the intention of the
resulting code sections a bit more clearly for the future.
