This colorful calculator sold in Europe is basically a TI-30 with some functions hidden by the keyboard plate. Inside you'll find the calculator chip of the SR-40 resp. the TI-30 models. Even the contacts of the missing keys are on the printed circuit board.

Compare this TI-15 with another European TI-30 variant, the TI-33 and don't miss the unique Studio 29.
