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. 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.
