'''David C. Broughton''',(died on February 02, 2017)<br/>was a British computer consultant and computer chess programmer. His first chess program [[Vega]], written on the [[Z80]] [https://en.wikipedia.org/wiki/NorthStar_Horizon North Star Horizon] machine, had finished 2nd behind [[Sargon]] at the [[PCW-MCC 1979|2nd PCW-MCC]] tournament held in London in November 1979, and he was soon recruited by [[David Levy]] and [[Kevin O’Connell]] to work for their companies [[Philidor Software]] and since 1981 [[Intelligent Software]]. He worked on the project [[Philidor]] which [[8086]] port emerged to [[Parker Chess]], and to the [[Saitek|SciSys]] [[Chess Champion Mark V]] <ref>[http://www.chesscomputeruk.com/html/chess_champion_mark_v.html Chess Champion Mark V] from [http://www.chesscomputeruk.com/index.html Chess Computer UK] by [[Mike Watters]]</ref>. Broughton’s work for the Mark V was in the form of Z80 [[Assembly|assembly]]. As the Mark V had a [[6502]] processor, the program had to be extensively translated and rewritten. So credit for the Mark V program has to go both to [[Mark Taylor]] and David Broughton, though David Levy is known to credit the Mark V to Taylor <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>.
