Il s'agit d'une TI-84 Plus normale munie d'une version d'OS modifiée (OS = Operating System, c'est-à-dire système d'exploitation), lui permettant de communiquer en USB avec un module vocal dont elle est surmontée.
Lors de la conférence internationale T3 2013 Adriweb avait eu le plaisir de tenir entre ses mains l'un des tous premiers exemplaires, muni d'une version d'OS "2.55/ORh" modifiée donc à partir de l'OS officiel 2.55MP.
Toutefois, la version d'OS récupérée par la suite sur notre échantillon était différente, "2.55/ORk". Nous comprenions alors que la dernière lettre minuscule indiquait donc la version de la modification 'vocale' apportée à l'OS 2.55MP de TI, et qu'il avait donc existé des versions intermédiaires: "2.55/ORi" et "2.55/ORj".
Il semblerait que ce soit la saison des mises-à-jour de la gamme TI-z80 en ce moment, car aujourd'hui Orbit Research sort lui aussi une nouvelle version de l'OS, "2.55/ORn", et il y a donc eu deux versions intermédiaires sans annonce publique, "2.55/ORl" et "2.55/ORm".
Les ajouts et corrections sont très nombreux.
Au menu des corrections, on notera la lecture correcte des textes affichés à l'écran ou dans les menus dans diverses situations auparavant problématiques:
- textes tronqués par des points de suspension
- textes comportant d'autres caractères spéciaux
- heure, quelque soit le mode horaire réglé
Au niveau des nouveautés, on retient:
- une assistance spécifique à certains écrans: réglage de l'heure, gestionnaire de mémoire, aide du catalogue si installée
- une alerte de batterie déchargée par vibreur pour le module vocal
- une indication spécifique des points d'intersection avec les axes lors de la 'lecture' sonore de graphiques (technologie SonoGraphTM)
Pour bénéficier de toutes les améliorations de ce nouvel OS, vous devrez également mettre à jour séparément le firmware de votre module vocal, qui lui passe directement de la version 1.0.4 à la version 1.1.0.
Mais, ça n'a pas chômé chez Orbit Research avec précisément 37 corrections de bug et pas moins de 20 ajouts de fonctionnalités, où le moindre petit détail semble avoir été pris en compte et étudié pour offrir la meilleure accessibilité possible au public concerné !
