- I do a little bit of 680xx programming for the Macintosh, and
- have occassionally seen mention of a "zero supressed register",
- denoted by e.g., ZA0. I couldn't find any mention of such an animal
- in the Motorola User's Guides, and am curious what it is. Is it
- something to do with the MMU and/or specific to a particular OS? I
- guess if I don't know what it is, I probably will never have a need
- for it, but I'm still curious.
