Maybe - but I'd like to see if the overall typeface is similar. There's something chunky about the n, i, FV, PMT, PV in the Brazil model - it's not just the % that is tall.

Yup - would make you think if it was being sold there at that time, we would see more in circulation?

I wonder, but the firmware is dated more recently.

But he had it for less than a day! Bear in mind that superficially, you might not notice the differences. Puzzle 1 and 1b are very straight-forward solves, and the HP-12c 'comma' (as I've been calling it) returns exactly the same result for 1, and one extra digit for 1A. It in fact beats the regular HP-12c for puzzle 2, returning a result as accurate as the HP-12c platinum.

It's only when you push the device with edge-case TVM problems, or by the sounds of it, specific NPV/IRR (I'm not in finance and I don't really understand what that calculates) or try to change the radix that you would encounter the error.
