Actually, it takes 4G of RAM to fill a 32-bit address space. A 64-bit
address space will require 4 billion times that much, or approximately
1.8x10^19 bytes of memory. Enough memory to fill a 128-bit address space
would be approximately 3.4x10^38. Making this much memory using current
technology would require more raw material than available in the solar
system. If you had bulk transmutation of elements you might be able to
do it.
I think what he really meant was that he wanted a 128-bit data bus and a
64-bit address bus. This would be much more useful in general, though
not too useful on a Z-80.

That was exactly what I thought when I saw Arfon's posting.
Might as well wish for a 12-cylinder engine and dual carbs for a lawnmower;
it would be more practical.
