Info: This calculator tastes different, it was a dear friend Joerg of datamath.org who gave it to me. At first glance, the TI-150 looks incredibly familiar to those of us who collect vintage Texas Instruments calculators. It combines the wedge-shaped design of the TI-2550 with the silver bezel surrounding the display of the SR-10. The screen itself appears to be a miniaturized Panaplex display, a feature already seen on desktop models like the TI-3500. Furthermore, its internal microchip, the TMS0852, was integrated with minor modifications into Canon's Palmtronic LD series most notably in the must-have LD-80. But just how rare is the TI-150? That is the ultimate question: by all accounts, these calculators are quite scarce, with rumors suggesting that only 4,000 units were ever produced.
