	EXACTLY!!!! What WE need to do is port something like MINIX to the
	Apple II using PRODOS as the filing system.  I suggest we start
	the project on the GS in order to create a running package by the
	end of the summer.  Then once the algorithm is set we can port it to
	the II+/e/c etc.

	All this disscussion about a MMU is useless.  The Memory Manager
	Toolbox will be plenty for single user multitasking. You HAVE to
	have a hardware MMU only when you want to run multiuser to prevent
	one user from tromping on others.  In a single user environment if
	memory get's trampled...it just means you can't multitask THAT
	particular application and you have to reboot.  IInix ( the name for
	Apple UNIX ) won't be able to multitask EVERYTHING at first, we may
	have to add patches to get weird programs like games to work
	and some may never work.  Such are the problems of developing your
	own OS.  But the important thing is to not give up on the project
	just because we don't have and MMU!!!!!!!!!!!!!!!!!!!!!!!!!

	Amen!!!!  This may be a difficult project but it is by no means
	impossible!
