TI-2000_1.jpg (42298 Byte)Okay, you finally found the TI-2000 in the Exactra part of the Datamath Calculator Museum. The label on the backside of the TI-2000 indicates with the bold "Made in Italy" already that the TI-2000 was manufactured for the European market.

TI-2000_Disp.jpg (56225 Byte)Let's compare it with the other Exactra models. First of all, the housing is known from the Exactra 21, the colour from the Exactra 20 and the missing Fix/Float switch from the Exactra 19.

Dismantling the TI-2000 reveals immediately the small display used in the Exactra 19 and Exactra 20, too.

But what kind of calculator is behind the TI-2000? None of the Exactra line! The printed circuit board (PCB) of the calculator is identical to the Exactra 20 but the missing Fix/Float switch is "hardwired".
