=Chess Challenger X=
==ACM 1986==
In 1986, at the [[ACM 1986|17th ACM North American Computer Chess Championship]], Fidelity showed up with a huge experimental, parallel machine, named ''Chess Challenger X''. Authors were [[Ron Nelson]], [[Dan Spracklen]], [[Kathe Spracklen]], and [[Danny Kopec]] as [[:Category:Opening Book AuthorsAuthor|Book author]]. It had a [[Z80]] controller, and 16 or more [[68000]] 16-bit processors. The controller was written in [[C]], the 16 or more Spracklen programs in [[Assembly|assembler]] <ref>[http://www.computerhistory.org/chess/full_record.php?iid=doc-431614f6ca4a7 The ACM's Seventeenth North American Computer Chess Championship and The Sixth World Microcomputer Chess Championship] from [[The Computer History Museum]], [http://archive.computerhistory.org/projects/chess/related_materials/text/3-1%20and%203-2%20and%203-3%20and%204-3.1986_17th_NACCC/1986%20NACCC.062303062.sm.pdf pdf]</ref>.
Chess Challenger X scored 50%, losing from [[Rebel|Recom]] and [[Belle]]. Notably, in the same tournament, another Fidelity computer programmed by the Spracklens with a Kopec book took part, as [[Fidelity|Fidelity Experimental]] with a [[68020]] processor. It did not score better in that strong field and finally placed 10th.
