Conchess was manufactured by Consumenta, a German company based in Munich. The owners of Consumenta Peter-Ingolf Genicke and Klaus Heyne became interested after witnessing the success of a new experimental chess program called Prinzchess 2.9 from Sweden programmed by Ulf Rathsman. This program had just finished second in the 1981 Microcomputer Chess Worldchampionship held in Stockholm, Sweden.
Ulf Rathsman agreed the use of Princhess and the chess computer brand Conchess was launched in 1982. Conchess only lasted through 2005, but during this short period they build beautiful modular chess boards and chess modules.
