Merlin,
a computer chess program developed in the late 70s and early 80s by four students from Vienna University of Technology, Hermann Kaindl, Helmut Horacek, Marcus Wagner and Roland Schreier, supported by project supervisor Werner DePauli-Schimanovich-Göttig. Merlin competed at various ACM North American Computer Chess Championships and two World Computer Chess Championships in the 80s, the WCCC 1983 in New York and WCCC 1989 in Edmonton, at the WCCC running on IBM 370 compliant Siemens 7.890 F (1983) and IBM 3090 (1989) [1]. It won the International Computer Chess Tournament 1984 in Baarn, The Netherlands [2].
Disney's version of Merlin [3][4]

Internals

As mentioned in Werner DePauli-Schimanovich's 2006 book Europolis 6 [5] and the reprinted paper Das Schachprogramm Merlin ... by Helmut Horacek and Marcus Wagner [6], Merlin was initially based on the didactic program Chess 0.5 by Larry Atkin and Peter W. Frey, as published 1978 in Byte Magazine, also written in Pascal [7] except some time critical, often called routines, which were re-written in CDC assembly by Wagner. Merlin was basically a brute-force depth-first searcher with knowledge-based selectivity [8] , using extensions as well as null move to determine threats [9] .
