  If you are using just a plain-vanilla 68000 in your machine, this is
completely impossible.  If you have installed a 68010 in your ST (I tried
it, and was in the process of hacking TOS to work with the '010, but lost
interest), there MIGHT be a way to do it (the 68010 has some _really crude_
method built-in for handling memory swaps).  If you somehow shove a 68030
into your ST's 68000 socket, you would then be able to use the '030's
built-in PMMU (paged memory management unit) to do the dirty work for you
(the "Virtual" INIT for the Mac does this, and I would assume something
similar could be whipped up by some intrepid ST programmer.
