'''Mark Taylor''',<br/>
a British computer chess programmer, in the 80s working for [[David Levy|David Levy's]] and [[Kevin O’Connell|Kevin O’Connell's]] companies [[Philidor Software]] and [[Intelligent Software]]. Mark Taylor, a recruit from outside the computer chess tournament circuit, was a [[6502]] expert who developed his programs on a [[Commodore PET]]. The [[Saitek|SciSys]] [[Intelligent Chess]] <ref>[http://www.chesscomputeruk.com/html/intelligent_chess.html Scisys Intelligent Chess] from [http://www.chesscomputeruk.com/index.html Chess Computer UK] by [[Mike Watters]]</ref> computer and [[PetChess]] were mainly programmed by Mark Taylor. In an interview David Levy mentioned Mark Taylor as the most talented and genius programmer of [[Intelligent Software]] <ref>[http://www.schach-computer.info/wiki/index.php/Levy,_David Interview with David Levy, Feb. 2006 by 'hard] from [http://www.schach-computer.info/wiki/index.php/Hauptseite_En Schachcomputer.info - Wiki]</ref>.

Mark Taylor worked with Levy to produce a program for a [https://en.wikipedia.org/wiki/Hitachi_Ltd.

Levy developed a chess playing algorithm for this chip which played fully legal chess including [[Promotions|pawn promotion]], [[En passant|en passant capturing]], [[Castling|castling]], and even managed mate with KR v K in some versions all in 160 nibbles of RAM. A piece of work that Taylor is still rightly proud of today <ref>[http://www.chesscomputeruk.com/html/chess_computers_-_the_uk_story.html Chess Computers - The UK Story] from [http://www.chesscomputeruk.com/index.html Chess Computer UK] by [[Mike Watters]]</ref>. The chip went into a series of small portable [[Saitek|SciSys]] machines - [[Mini Chess]], [[Mini Chess#Junior|Junior Chess]] and [[Mini Chess#Graduate|Graduate Chess]], all released in early 1981. The 4-bit program also initiated [[Eric White|Eric White's]] involvement in computer chess business and long time collaboration with Levy, when [https://en.wikipedia.org/wiki/Hong_Kong Hong Kong] based manufacturer ''White and Allcock'', forerunner of [[Newcrest Technology]] introduced the CXG brand with [[CXG Sensor Computachess]] in 1981 <ref>[http://www.schach-computer.info/wiki/index.php/CXG_Pocket_Chess CXG Pocket Chess] from [http://www.schach-computer.info/wiki/index.php/Hauptseite_En Schachcomputer.info Wiki]</ref> <ref>[http://www.schach-computer.info/wiki/index.php/CXG_Sensor_Computachess CXG Sensor Computachess] from [http://www.schach-computer.info/wiki/index.php/Hauptseite_En Schachcomputer.info Wiki]</ref>.

Taylor was also involved in the [[Philidor]] project, and was responsible to translate the [[Z80]] program for the SciSys [[Chess Champion Mark V]] 6502 branch, also deployed for the [[Milton Bradley Phantom]].
