- Time-warp alert: AFAIK the 68020 and its optional MMU hardware weren't
- available until 1985. Si I think Michael is saying that there was no real
- choice.

- They made provision allright (MEMF_PUBLIC), but it was decided to let features
- come before protection. I still feel this is one of the decisions that make the
- Amiga stand out from the crowd.

- afraid to do something worse than UNIX!
