Could somebody say a bit more about clock doubling and all that? I
found under 1.0 that I had to say "hiclock" to get my Cardinal 700
card to work properly. I've tried all the hacks I can think of, and
1.1 still needs hiclock. I have a feeling it would help for me
to understand exactly what hiclock does and why.
