Facts:
1. the ST line is a 68000 hard and soft box (no '10, no '20, etc)
2. We would all love to have efficient and safe multitasking.
3. The new memory chips are easily available in 100ns to 80ns variety.
4. The problem with the 68851 (?) MMU chip is the 50ns or so delay.
5. We dont want wait states.
6. What is called MMU in the ST is not what the rest of the computer world
   call a MMU, whose functionnalities are needed to implement safe
   multitasking (segment protection and translation).
7. It should not be very hard to insert a MMU between the 68000 and the
   rest of the chips.

Question:
How to stuff fast memory, MMU chip in the ST, and slightly modify the
&|"'@)$#% GEMDOS call to have the necessary process/memory call cleaned up ?

May be an answer is OS9, or a modified Minix, just keeping the graphic/window
part of the then defunct GEMDOS ???

If you are not harware interested, just forget it,
If you think I said something totaly brain damaged, well, let me know.
