Texas Instruments introduced in 1984 with the TI-30 Galaxy a calculator with pedagogical features in mind. It got large keys in a meaningful layout but sports only an 8-digit display and disappointing calculating accuracy.
The TI-52 introduced in 1986 improved both disadvantages and could be called a perfect calculator. Don't miss the TI-52 Prototype using the beige housing of the TI-30 Galaxy.
The first generation of the TI-52 was manufactured in Japan by Toshiba but Texas Instruments shifted in 1987 the production together with the TI-30 Galaxy to its Rieti facility in Italy.
Dismantling the featured TI-52 manufactured in February 1986 and comparing it with a later TI-52 assembled in Italy reveals some interesting differences. The original design makes use of two rigid printed circuit boards (PCBs) while the second generation is based on only one, two-sided flexible PCB.
Compare the housing of the TI-52 with the stylish TI-52 SOLAR.
