If you are used to making calculations with Reverse Polish Notation then this calculator isa welcome replacement for the original 50-year old edition.However, many of its problem-solving capabilities (= programming) are nowmuch easier to do on a PC or laptop where one has much more visibility of what one is doing.

Upon reception I noticed that there was no protective foil on the display the keyboard nor the back. I found this to be very odd and a potential indication of a fake. However everything else seem to be fine.

In het begin van de jaren 80 was de HP 41C de rekenmachine die iedereen wou hebben maar slechts weinigen zich konden veroorloven. Deze 12c is de opvolger van de opvolger en een heruitgave... aan een prijs waar ik me tegenwoordig helemaal niet druk over maak. Het is mijn standaard rekenmachine geworden.De handleiding is van een ongezien fantastische kwaliteit (en ik mis dat bij nieuwe rekemachines heel erg. Ook de handleiding van een HP prime vind ik maar niets).Alllen de toesten zijn niet van de kwaliteit die je op de oorspronkelijke HP machientjes vond.

Härlig retro räknare och supersnabb leverans.

La mejor calculadora RPN cientifica que puedes encontrar.Además es pequeña.

I had one of these when they were originally launched, back in the early 1980s and loved it. I used it for my A’Levels and degree but sadly had it stolen. By then it was no longer available on the market. When I saw that a Collector’s Edition was available I was so excited.I was a little concerned that Amazon has it described as a Financial calculator but after looking carefully at the images and sending off a quick question it was confirmed that it was the 15c Scientific calculator so I had to buy it.The build quality is superb, the keys are so nice to use, the lcd is crisp and clear and the landscape, Voyager, format is such a joy to use. It also comes with a full and comprehensive manual, something of a rarity today.It might seem expensive for a scientific calculator but in fact it is worth every penny. It is a powerful scientific calculator with programming capability. Matrices, polar and stats are all available. And the RPN logic is so powerful and, once you’re used to it, is so intuitive. Since the calculator no longer has the sapphire on silicon NUT processor, the battery life might not be measured in decades but it will still be impressive.

Edizione da collezione. L'utilizzo di una HP RPN programmabile è un viaggio nella storia. Cofanetto, morbida custodia di qualità e owner's handbook di 294 a colori. Stavolta hanno fatto le cose per bene !
