Scientific model with a fluorescent display; similar in styling to the TI 30.

At first glance is the European TI-45 identical to the SR-40. Surprisingly the TI-45 features a green fluorescent display, a major exception in the Majestic-line.

Two variations of the TI-45 were reported, they differ in the mask over the display. The later model with a molded TI-logo and TEXAS INSTRUMENTS nameplate. Our model is the earlier one.
