That seems like a strange number. I’d have thought that the sweet spot for cheapest large quantity flash ROM would be a bit larger. Someone might want to examine the board to see which chip they used, in case there’s hidden gold. (Buried extra functionality is traditional in calculators, back to when the only difference between a basic four-banger and one with square root and memory were the missing keys on the keyboard.)
With the TI-84 in use for so long, I’m surprised that no one has hacked the hell out of it. (Or have they?)
