It seems like a re-implementation to me. Take this TVM problem from Dieter:

N: 10
i: ?
PV: 50
PMT: -30
FV: 400
P/YR: 1
end-mode

There isn't a single HP financial calculator that can return an interest rate on this.

Except for this HP-12c 'brazil/comma' version.

That would apply to many new HP-12cs though?

I wonder about this, but I also wonder why.

Exactly - it's not hard to get a copy of the HP-12C firmware - so if you're faking it anyway, why not use that?

Bob, I'm not referring to the Prestige. This a gold HP-12c sold in Brazil. Someone previously pointed out the taller '%' symbol suggesting it may be fake - however, I've attached a picture from the official HP Brazil website.

The picture also matches the image that people have posted in their reviews. Most people are happy with the product, but there is certainly a recurrent theme of people who have noticed some functions aren't working. It's only when you really push the TVM problems that you find it falls very short of the ability of regular HP financial calculators at times (on other occasions exceeding it).
