Since the AT/Once apparently only connects through the 68000 socket, there
should be no problem.  A 68000 signals are identical on all of the
machines.  In fact, I see no reason why the AT/Once cannot be used on
ANY 68000 based machine, provided you port the software also.

Whatever you plug into the 68000 socket must look, smell, and react like
a 68000.  The 286 on the AT/Once must be accessed as a peripheral to the
68000.  Whatever they have done, it seems to be the simplest way to do
it since I can only see a few support IC's.

I would suspect that if you unsolder the 68000 provided on AT/Once and
replace it with a socket, an accellerator (Lucas) could possibly be
utilized also.  Of course the stack of boards could get pretty high!

These are only my opinions and experiences.  No Flames!
Of course, helpful information will be appreciated.
