Home * Engines * Chess-Master

Chess-Master [1]

Chess-Master,
a dedicated chess computer series manufactured in the 80s by VEB Mikroelektronik „Karl Marx“ Erfurt, East Germany, in West Germany sold by Radiophon. Chess-Master ran on an 8-bit U880 CPU, which was an unlicensed Z80 clone, and had 10 KB ROM and 2 KB RAM. The chess program was initially written by Dieter Schultze and Rüdiger Worbs.

Automatic piece recognition was implemented with Hall effect sensors under each square of the chessboard, while pieces had two reverse directed permanent magnets with different compensation embedded, so that a cyclic running multiplexed I/O program, also polling the keyboard, could recognize the pieces [2] [3] .

Chess-Master played the 3rd World Microcomputer Chess Championship 1983 in Budapest, running on a 2.5 MHz processor, searching 12 - 15 nodes per second [4], and competed with Fidelity Sensory 9 for the title of the best commercial entry [5].

Chess-Master Diamond [10]

The improved Chess-Master Diamond was contributed by Rüdiger Worbs and Wolfgang Pähtz [11] , and was released in 1987 [12] .
