To build a computer with 48-bit addresses and to give it 2**48 memory cells, you would need more cells than there are atoms in the Earth. Addresses bigger than 48 bits are probably not worthwhile, unless you need a discontiguous (sparse) address space. -- Andrew Klossner (decvax!tektronix!orca!andrew) [UUCP] (orca!andrew.tektronix@csnet-relay) [ARPA]
