I never said that the 1997 programs needed to be run at 200mnps.  You said that.
 I think the 1997 programs were close to DB, not that far behind.  1997 version
of Rebel on todays fastest single AMD would beat DB 96/97 in my opinion.  DB
96/97 needed the blazing speed, not the commercials.  The HW/SW today would beat
DB 96/97.
