First the gripe:  I called up PH today to find out postage and handling costs.
In the process, I found out that I won't get a $60 discount on the
Mac version, since the earlier version I bought was for the PC. (Of
course there was no Mac version back then, but thats beside the point.) Is
this official policy on PH's part, or did I just run into a salesperson
who erred on the side of caution?

Now my question:  Does MacMinix switch user processes into user (68000) mode,
or does it allow user programs to execute supervisor mode instructions.  If
the above method is not used, then does the included cc check for
illegal operations (like overstepping memory bounds)?

The thrust of my question is whether MacMINIX can be used as a secure 
multiuser system.
