a [[Dedicated Chess Computers|dedicated chess computer]] with integrated travel sensory pegboard. It was the '''first''' own computer under the brand name '''CXG''', manufactured by ''White and Allcock'', the forerunner of [[Newcrest Technology]] <ref>The very first one was the [[Cassia Chess Mate]] aka CXG Computachess I, a [[Clones:Category:Clone|clone]] of [[Ron Nelson|Ron Nelson's]] [[Chess Challenger|Chess Challenger 10]]</ref> <ref>[http://www.schaakcomputers.nl/hein_veldhuis/database/files/09-1979%20%5BA-3976%5D%20Cassia%20-%20Chess%20Mate.pdf Cassia - Chess Mate], pdf hosted by [[Hein Veldhuis]] (Dutch)</ref> <ref>[http://www.hiarcs.net/forums/viewtopic.php?t=6768&start=205 Re: Ron Nelson Chess Challenger 10] by [[Ron Nelson|ChessChallenger]], [[Computer Chess Forums|Hiarcs Forum]], January 24, 2016</ref>.
