'''Harm Geert Muller''' ('''HGM'''),<br/>
a Dutch physicist and since 1976 computer chess programmer. He wrote a blitz program for the [[PDP-11]] and programs for the [[6800]] and [[6502]] 8-bit µ-Processors, released under the name [[Usurpator]], which competed in several [[Dutch Open Computer Chess Championship|Dutch Computer Chess Championships]]. In [[DOCCC 1986|1986]] HGM came up with a matchbox computer with a [http://www.baltissen.org/newhtm/65sc816.htm 65SC816] CPU for the purpose of running Usurpator <ref>[[Jaap van Oosterwijk Bruyn]] ('''1986''').

'''Harm Geert Muller''' ('''HGM'''),<br/>
a Dutch physicist and since 1976 computer chess programmer. He wrote a blitz program for the [[PDP-11]] and programs for the [[6800]] and [[6502]] 8-bit µ-Processors, released under the name [[Usurpator]], which competed in several [[Dutch Open Computer Chess Championship|Dutch Computer Chess Championships]]. In [[DOCCC 1986|1986]] HGM came up with a matchbox computer with a [http://www.baltissen.org/newhtm/65sc816.htm 65SC816] CPU for the purpose of running Usurpator <ref>[[Jaap van Oosterwijk Bruyn]] ('''1986''').
