Regardless, there are some important differences in these calculators that are worth discussing. I teach Finance and the current calculators are unrecognizable to me. If you've been around the finance industry for a while, you know this is the best calculator on the planet.
#Hp 12c financial calculator 30th anniversary edition code
Maybe these Invertec-made HP-12C's are the ones that people complain about as being not as good as the "old ones"? You might want to google that, there's info out there which supports this conjecture.Īnyway, if these 30th anniversary edition ones made in 2011 have become scarce and cost too much (I just bought one on Amazon, August 2015, brand-new in box for $99) and you just want a "regular" HP-12C, but you cannot somehow determine whether the very actual calculator that you will receive has model code (on the back) KN or IN, or whether the % key has round o's or vertically-stretched o's, I wouldn't buy it. The haptics on these keys are a model for all electronic devices and really contribute to rapid, accurate, touch-typing. If you buy a regular "non-anniversary" HP-12C, it might be made at the Invertec factory, the "IN" in the model number, which means it will have a slightly different font on the keys (look at the % key), slightly duller and less-legible shades of orange and blue paint for the f and g functions, and a slightly mushier key feel with less snappy (but silky!) feedback pop-which is too bad, because this keyfeel is really one of the best things about the HP-12C. And that's when I learned about the different factories that HP uses. Last year I bought a regular HP-12C model # HSTNJ-IN04 that failed after less than one year-which is unusual, because these things are famous for lasting decades. The 30th Anniversary Edition with model # HSTNJ-KN05 is the best one to get, because it was only made at the Kinpo factory-which is the "KN" in the model number. There is no acceptable substitute for this calculator! It's the perfect tool for rapid number-crunching.
