There is more information.  The two programs were rebel and genius.  This was
reported here by someone that attended a talk by either Hsu or Campbell and they
asked.  Second, 10-0 was the tip of the iceberg.  It was actually 38-2, as
reported in IEEE Micro in the current issue.  And finally, DB Junior played
dozens of public games.  At two consecutive Supercomputing conferences I walked
into the tournament hall and found it playing GM players like Robert Byrne (to
name just one GM).  I believe that Hsu reported that DB Junior's performance
rating over a whole bunch of games was 2750 or something close.  Deep Thought
II produced a 40/2hr performance rating over 2650 to take the final Fredkin
prize.  So there is _plenty_ of data about the machine...  And it is all pretty
impressive data to boot..
