- Yes but code hunks can contain data and data hunks can contain code. You

- another processor for all cases(without an unlimited machine).

- I don't believe you would get anywhere near 30-40% of real world 680x0
- Amiga programs static translated to PPC (unless you have an unlimited machine
- of course). In the end it is more practical to use dynamic-compilation and
- the 680x0 is a nice chip to do that with since programs are suppose to use
- cache clearing calls and a MMU is not required in AmigaOS case.
-
- The real question is will there be a interpretive or dynamic-complation
- engine supplied with the PPC boards/machines. And if the in the likely
- event of interpretive at first when would dynamic come along.
