Ah, right. Anyway, buttons (1/x), (x^2), and 3,6,9 don't work right on my ti1270 emulation. I checked the bits on the die pic under the smudge for faults. I found 1 bad bit! But seems to have no effect at all on the emulation.
ti1270raw.bin offset $174, change $11 to $51.
D'oh- sorry about that bit. I just checked the full die again and I didn't notice any other errors.
That's a weird collection of buttons not to work- I'd expect a full row or column, not a mix of buttons on 3 different columns and 4 different rows.
seems to have no effect at all on the emulation.
