TI-92-II_PCB.jpg (174265 Byte)Beyond the additional 128k Memory you get the choice of 5 user languages (English, French, German, Italian and Spanish). We assume that the TI-92 II is identical to the TI-92 but integrates the TI-92 E module available in Europe.

The next upgrade was done either with the TI-92 PLUS Module containing 384k Byte Flash ROM or the TI-92 Plus calculator itself.

A serial port of the calculators allows the connection to the Calculator-Based Laboratory system CBL, its successor CBL 2, the Calculator-Based Ranger CBR and its successor CBR 2.
