   They would've been wiser to split a 32-bit address across two registers   
   instead of using a 4-bit shift and add.  That would've allowed for an   
   easier transition to 32-bit.   
      
   If you want to read about some of the problems transitioning to 32-bit,   
   see the 68000 micro-procesor which had 24-bit addresses.  Programmers   
   found uses for those upper bits ...  The 68000 series migrated to   
   32-bit addresses and couldn't execute older software.   
      
   Sound familiar? E.g., x86 A20?  (No foresight.)
