Encore une belle machine de l’\u00e9poque 1975\/1976. La SANTRON 300SR<\/em> a un aspect plut\u00f4t anonyme. Elle ne semble ni connue ni recherch\u00e9e. Un mod\u00e8le \u00e0 oublier ?<\/p>\n

Non bien s\u00fbr ! Que nous montre-t-elle de prime abord ? Une silhouette biseaut\u00e9e qui fait penser \u00e0 Hewlett-Packard<\/em>, un calage d’affichage \u00e0 gauche, des chiffres rouges constitu\u00e9s de micro-segments, voil\u00e0 qui \u00e9voquerait bien l’univers de\u00a0Novus<\/em>.<\/p>\n

Pratiquons quelques tests de calculs pouss\u00e9s pour tenter de d\u00e9celer la signature de l’\u00e9lectronique. Voil\u00e0 le verdict qui tombe, nous avons affaire \u00e0 un processeur de marque Rockwell<\/em>, le m\u00eame qui anime la Rockwel Anita 1041<\/em> (*), la Sanyo CZ-2172<\/em><\/a>, et l’Olympia CD603<\/em><\/a>. Du tr\u00e8s beau monde.<\/p>\n

La SANTRON 300SR<\/em> est une calculatrice simple mais\u00a0empreinte d’une classe discr\u00e8te. La courroie, le galbe concave travaill\u00e9 de la fa\u00e7ade en t\u00e9moignent.<\/p>\n

Sur le plan du calcul, dix chiffres plus deux d’exposant (pas de chiffres de garde) pour des calculs scientifiques classiques. La pr\u00e9cision est tr\u00e8s correcte, la vitesse de calcul dans la fourchette haute. Le clavier, sans d\u00e9clic, est parfait. Enfin trois piles AA alimentent l’afficheur \u00e0 diodes.<\/p>\n

Une originalit\u00e9 : en cas d’erreur, quatre segments s’allument tout \u00e0 gauche pour dessiner le \u00ab\u00a0O\u00a0\u00bb de Overflow<\/em>, (= d\u00e9passement de capacit\u00e9).<\/p>\n
