As you know, I am mch more of a hardware person, but I have talked ot the
1793 etc disk controllers (and the 279x is much the same as a 179x with
some of the support chips built-in). If oyu have any specific questions I
will see what I can rememebr...
I also have the data sheets for both these chips if you don't have them
