\"Tecxon\"<\/p>\n

 <\/p>\n

J’ai eu la chance d’acqu\u00e9rir cette rare et fort jolie TECXON<\/em>, qui m’est venue de Bulgarie.<\/p>\n

Une marque peu connue, peu \u00e9toff\u00e9e (moins de 5 mod\u00e8les r\u00e9f\u00e9renc\u00e9s \u00e0 ce jour), peu assum\u00e9e avec son manuel de 6 pages\u00a0minuscules mentionnant juste\u00a0Slide Rule<\/em> en couverture, signe d’une TECXON<\/em> vraisemblablement bon march\u00e9.<\/p>\n

Comme la Logitech LC90S<\/em><\/a><\/span>, la TECXON<\/em> s’orne en fa\u00e7ade d’une illustration de\u00a0la courbe de Gauss<\/em>. Le calcul des probabilit\u00e9s selon la distribution normale \u00e9tait en fin des ann\u00e9es 70 le signe d’une machine puissante, le nec plus ultra des fonctionnalit\u00e9s scientifiques de poche.<\/p>\n

La 650<\/em>, en parfait \u00e9tat de marche et aux contact m\u00e9talliques intacts en 2024, souffre cependant d’un mal nouveau. La nappe caoutchout\u00e9e charg\u00e9e d’\u00e9tablir la liaison interne entre les touches et la carte \u00e9lectronique se dess\u00e8che et se d\u00e9sagr\u00e8ge petit \u00e0 petit, avec pour cons\u00e9quence une r\u00e9ponse difficile des touches aux emplacements concern\u00e9s. Un mal\u00a0probablement appel\u00e9 \u00e0 se d\u00e9velopper sur les mod\u00e8les les plus anciens.<\/p>\n

Ci-dessous \u00e0 gauche, d\u00e9tail de la nappe, \u00e0 droite la tr\u00e8s r\u00e9pandue puce NEC D1856G<\/em><\/p>\n
