   The assembler works simply by   
   adding a G though, which is all I need.   
      
   Ok, so the person writing the assembler   
   may potentially need to change opcodes.   
      
   But you could keep the opcodes the same if   
   you were happy to go pure 64 bit.   
      
   Not an actual zarch.
