>Which Mephisto Version Beat Deep Thought?
An Experimental version of Mephisto defeated Deep Thought(predecessor to DEEP
BLUE) in the 1989 North American Computer Chess Championship
this was not a commercially available dedicated Mephisto computer,but my guess
is it contained the Mephisto Portorose program by Richard Lang
here is the game:
NACCC 1989
Round 5
Mephisto X -- Deep Thought
