It seems olcott also knows that HHH fails to reach the machine address 
00002183, because it stop the simulation too soon. A correct simulation 
by the unmodified world class simulator shows that it does reach machine 
address 00002183. Even HHH1 shows it. But HHH fails to machine address 
00002183.
Why does olcott ignore this truth? The evidence is overwhelming.
