By the way, 64 bit addressing was not that useless. RAM size isn't the 
only thing here. A VAX has 32-bit address space at a time when machines 
shipped with 512K, and something like 4 Megs was considered huge. The 
large virtual address space still made a big change on how you could 
write your software.
