I have a really naive question about the MMU in the A2500: What does it actually *do* for you? I thought MMUs performed such functions as address translation, and were also used to produce separate address spaces for separate tasks. I didn't think that the A2500 used it for either of these purposes. Does the MMU have a concrete purpose when running AmigaDos, or is it only for Amiga Unix and/or future use? Just curious. Thank you! Bruce Bowers "I'm just some guy. I don't need a disclaimer."

There may (or may not) be MMU support in AmigaDos 1.4. I can hardly wait for a "protected" AmigaDos (as long as things don't slow down too much.)
