<span id="PrestigeMephistoX"></span>In round 5, [[Chess Challenger|Prestige Challenger]], operated by [[Dan Spracklen]], played [[Mephisto (H)|Mephisto X]] operated by [[Ossi Weiner]] and [[Thomas Nitsche]], as reported by [[Frederic Friedel]] <ref>[[Frederic Friedel]] ('''1984''').''Move from the East''.Report of the WMCCC 1983, [[Personal Computer World]], January 1984</ref> . At move 40, Mephisto had a big advantage, but started to miscalculate and after 75...Qc7, Weiner could hardly wait for the imminent adjournment and adjudication by the master, and had some arguments with [[Fidelity Electronics]] representative [[Peter Reckwitz]] <ref>[http://www.game-ai-forum.org/icga-tournaments/round.php?tournament=66&round=5&id=9 Budapest 1983 - Chess - Round 5 - Game 9 (ICGA Tournaments)]</ref> :
