Home * Engines * LogiChess

LogiChess,
the first chess program by Kaare Danielsen developed in 1981 for the Z80 processor. It competed at the 2nd European MCC 1981 (3rd place) [1] and two World Microcomputer Chess Championships in 1981 and 1983, at times supported by Hartvig Ekner [2].

SciSys & CXG

As 4K dedicated chess computer program, LogiChess was ported to the 6800 instruction set compatible Hitachi HD6301V1 and Newcrest 6301 8-bit controllers. It was sold in approximately 200.000 units [3] from SciSys as SciSys Explorer, SciSys Concord II and SciSys Companion II, and from RadioShack as Tandy 1650 [4]. Another 4K [5] branch was realized for Newcrest Technology, for the CXG Computachess III in 1984 [6], as well inside the CXG Star Chess of 1985 [7] [8]. According to its author, LogiChess is still the strongest 4K chess computer in the world [9].

Lexibook

The Motorola 6800 LogiChess branch was still in production in the 2000s, as used in all the Lexibook computers [10] with 68HC08 compatible microcontrollers [11] [12] [13] [14].
