'''CHEOPS''',<br/>
a '''Che'''ss-'''O'''riented '''P'''rocessing '''S'''ystem with a dedicated chess processor, developed end of the 70s at [[Massachusetts Institute of Technology|MIT]] by [[John Moussouris]], [[Jack Holloway]] and [[Richard Greenblatt]], derived from the original conception and design of a 8x8 hardware chess array instrumented by [[Edward Fredkin]]. CHEOPS was used by [[Alan Baisley|Baisley's]] [[Tech#Tech2|Tech 2]] and a [[Brute-Force|brute force]] version of [[Richard Greenblatt|Greenblatt's]] [[Mac Hack]] <ref>[[John Moussouris]], [[Jack Holloway]], [[Richard Greenblatt]] ('''1979'''). ''[http://portal.acm.org/citation.cfm?id=61701.67028 CHEOPS: A Chess-orientated Processing System]''. [http://www.doc.ic.ac.uk/~shm/MI/mi9.html Machine Intelligence 9], reprinted ('''1988''') in [[Computer Chess Compendium]]</ref>, but unfortunately have never competed in computer chess tournaments with this approach. According to [[Joe Condon]] and [[Ken Thompson]], already working on a chess hardware for [[Belle]], the problem with CHEOPS was the lack of positional [[Evaluation|evaluation]] support <ref>[[Joe Condon]], [[Ken Thompson]] ('''1982''').
