From a programming point of view, how easy is accessing IDE compared to a
typical FDC ('765 or similar)? I did write some assembler to access an IDE
drive about 12 years ago, but have long since forgotten details! :-)
IDE (or CF) is easier than floppy. First, it's buffered so you do not
have the tight timing problem of FDC data transfer rates. Second, the
the interface is around the same as for an PPI or serial port more or less.
