TI-30 Galaxy was designed in Europe with pedagogical features in mind. It got
large keys in a meaningful layout.
The first generation of the TI-30 Galaxy was manufactured in Japan by Toshiba, the company behind the TI-66 Programmable. Dismantling this TI-30 Galaxy reveals a single-chip calculator circuit T6975S, obviously an enhanced version of the T6974S found in the TI-30 SLR line.
The T6975S was used in the TI-30 Galaxy Solar and their twins for the US market, the TI-35 Galaxy resp. TI-35 Galaxy Solar.
Production of the TI-30 Galaxy was later shifted to Italy, don't miss the second generation of the TI-30 Galaxy sporting a different calculator circuit and powered by two batteries instead of just one battery.
If you are interested in the calculating accuracy of scientific calculators don't miss the Calculator forensics and trace down the TI-30 Galaxy to the Canon card F-63 introduced already in 1980.
The more powerful sibling TI-52 enhanced the display
capability to 12 digits and improved the disappointing calculating accuracy of
the TI-30 Galaxy.
