    That "part" being the 65C816 micro-processor. :)

    To clarify that a little, you mean exceeding 4 MB in the _memory
expansion slot_. My Apple IIgs is perfectly DMA compatible with its
5.125 MB of memory, simply because 1.125 MB of that memory is located 
on the motherboard with the remaining 4 MB in the expansion slot. Any
memory on the motherboard does not count when talking about DMA.
