The Fifth World Microcomputer Chess Championship took place from September 7-15, 1985, at the World Trade Center located at the Zuidas in Amsterdam, the Netherlands. Despite a field of 16 chess computers in the commercial group, there were six participants with up to three entries each. A 32-bit version of Richard Lang's Mephisto Amsterdam won conveniently, followed by two 16-bit versions of the same program [1] . Additionaly, there was an amateur group with five participants. The title of the Amateur World Microcomputer Chess Champion was confidently won by Frans Morsch's program Nona with a 100% score.
