The GGM had exchangeable modules with programs from multiple authors, [[Boris|Boris 2.5]] based on [[Sargon|Sargon 2.5]] by [[Kathe Spracklen|Kathe]] and [[Dan Spracklen]] further improved by [[Terry Fredrick]], [[Morphy]] by [[John Aker]], the opening module [[Morphy#Gruenfeld|Gruenfeld]] by [[Larry Atkin]], [[David Slate]] and [[John Jacobs]], the endgame module [[Morphy#Capablanca|Capablanca]] by Atkin and Slate, and the [[Steinitz]] module by Atkin, all [[6502]] based. There were also other game modules available, such as [[Checkers]] <ref>[[http://www.schaakcomputers.nl/hein_veldhuis/database/files/12-1980%20%5BK-1001%5D%20Applied%20Concepts%20-%20Borchek%20%28championship%20checkers%20module%29.pdf|Applied Concepts - Borchek (championship checkers module)]] (pdf) by [[Hein Veldhuis]]</ref>, and the [[Othello]] program [[Peter W.

=Tournaments=
==ACM 1980== 
The [[Boris|Boris X]] GGM module was registered for the [[ACM 1980]]. A brief description is given in the tournament booklet with [[Applied Concepts]] CEO [[Alan Mead]] as representative <ref>[[http://www.computerhistory.org/chess/full_record.php?iid=doc-431614f6cdeeb|The Eleventh ACM's North American Computer Chess Championship]], [[http://archive.computerhistory.org/projects/chess/related_materials/text/3-1%20and%203-2%20and%203-3.1980_11th_ACM_NACCC/The_Eleventh_ACMs_North_American_Computer_Chess_Championship.1980.062303015.sm.pdf|pdf]] from [[The Computer History Museum]]</ref> :
|| {{__BORIS EXPERIMENTAL__, Alan Mead, Applied Concepts, Garland, Texas}}

{{The program uses [[Alpha-Beta|alpha-beta]] pruning with recently developed and improved search heuristics. The program runs in 8k of program space and has nine levels of play including two tournament levels. The tournament level play is expected to be 100 points stronger than the present BORIS 2.5 program.}} ||

But //Boris X//, despite registered, finally did not play the [[ACM 1980]]. [[Kathe Spracklen]] had filed a protest, claiming //Boris X// is too similar to //Sargon 2.5//, and requested mutual comparison of the source code. After John Aker admitted that //Boris X// was a revamped //Sargon 2.5//, //Boris// was rejected <ref>[[http://www.schaakcomputers.nl/hein_veldhuis/database/files/01-1981%20%5BE-4701%5D%20Applied%20Concepts%20-%20Morphy%20Edition%20Master%20Chess%20%28module%29.pdf|Applied Concepts - Morphy Edition Master Chess (module)]] (pdf) by [[Hein Veldhuis]]</ref> <ref>Evan Katz (**1981**). //The Eleventh North American Computer Chess Championship//. [[Personal Computing]], Vol. 5, No. 2</ref>.

==WMCCC 1981==
The Great Game Machine participated at the [[WMCCC 1981]] in [[http://en.wikipedia.org/wiki/Travem%C3%BCnde|Travemünde]] with the [[Morphy|Gruenfeld/Morphy/Capablanca]] and [[Morphy|Applied Concepts X]] entries in the commercial and open groups. The Applied Concepts personal involved withdrew their programs after some rounds from both sections of the tournament, due to a bug in their [[Morphy#Capablanca|Capablanca]] module <ref>[[David Levy]] and [[Kevin O’Connell]] (**1981**). //A New World Champion//. Chess, October/November 1981, [[http://www.chesscomputeruk.com/html/publication_archive.html|Publication Archive]] from [[http://www.chesscomputeruk.com/index.html|Chess Computer UK]] by [[Mike Watters]]</ref>

==ACM 1981== 
At the 12th [[ACM 1981]], [[Boris|Boris X]] was mentioned in the tournament booklet with a list of its authors and Applied Concepts representatives <ref>[[http://www.computerhistory.org/chess/full_record.php?iid=doc-431614f6ce737|The Twelfth ACM's North American Computer Chess Championship]], [[http://archive.computerhistory.org/projects/chess/related_materials/text/3-1%20and%203-2%20and%203-3.1981_ACM_NACCC/1981_ACM_NACCC.sm.062303017.pdf|pdf]] from [[The Computer History Museum]]</ref>, but did not participate, likely also because [[David Slate]] was already competing with [[Nuchess]]:
