The
TI-30 Galaxy was designed in Europe with pedagogical features in mind. It got
large keys in a well-thought layout.
The first generation of the TI-30 Galaxy was introduced already in 1984 and manufactured by Toshiba in Japan. It is based on the T6975S single-chip calculator circuit. In 1987 the complete design of the TI-30 Galaxy and its sibling TI-52 was revised and production of the calculators shifted to a Texas Instruments facility located in Rieti, Italy.
An obvious difference between the first and second generation of the TI-30 Galaxy is the number of batteries! The first generation uses one LR44 battery, while the second generation uses two cells. From much higher importance is the electronics inside. The Texas Instruments CD4808 calculator circuit used in the TI-30 Galaxy manufactured in Italy is less accurate in most calculations than the Japanese version. This is unusual for a TI calculator chip, normally the Toshiba IC's are the disappointing ones.
The design of the TI-30 Galaxy was changed in 1988 again, don't miss the black colored TI-30 Galaxy.
