    For those blissfully ignorant [like I was until today], the PIO mode is
    the bulk of functionality and the SCB mode is an extension of the PIO mode.

    So, the PIO chapter is sehr busy, many tables or register images... Let
    me regather my arcane powers before returning to this forlorn hope.

    NOTE: Lots of images that IBM didn't label. I think I got 'em all.
    Maybe. -LFO

    No images [yet]. The PIO section convinced me that the image naming
    convention HAS to be SIMMple.
