Indeed. Maybe it is at 0xfff00000, but the A1200's 68060- or ppc.library
protects the area from the M68k.
The 68k boot code is copied to 0xfff03000 with CopyMem() while multi-
tasking and MMU are still enabled, so it might help to switch everything

Ahhh, thanks! The formatting was gone, so I got confused.
So it's true that the first slot grows downwards and the second slot

But that's ugly! I wonder what happens when you put in a 4 MB SIMM
together with the 32 MB SIMM? I hope the memory is contiguous?
