This TI-35 Galaxy is 100% identical with the TI-30 Galaxy sold in Europe. It was designed in Europe with pedagogical features in mind and introduced large keys in a well-thought layout to the students.

Manufactured in Japan it uses a Toshiba calculator integrated circuit similar to the TI-30 SLR. The same chip was used inside the TI-30 Galaxy Solar and the TI-35 Galaxy Solar sporting additional solar cells.

We discovered three "calculator pairs" in the Galaxy series:
