I was wondering whether C= supported directly writing to the chips
registers.  I know you would have to do a Forbid()/Permit() and
make sure blitter DMA was finished etc. to be multitasking friendly,
but does C= state that any new chip set will be compatible with
the old one.

ie. would my program break on an Amiga 4000 if I wrote to the 
chips for speed.
