HP 15C Financial Calculator - Collector's Edition

1980年代後半米国留学中にHP-15Cを購入しました。ヘビーユーザーではありませんが、既に40年弱使用しています。壊れず未だに使えているのですが、他に代え難いデザインと逆ポーランド記法とキータッチが大好きなので、今回HP-15C Collector's Editionを購入しました。かなり割高な価格でしたが、hpロゴが付いている点もファンにはたまりません。コレクター仕様ですが普段使いしています。復刻されて演算速度が速くなっているそうですが実感できません。キータッチは少しソフトになっている感じです。iPhoneのエミュレーターアプリも使っていますが、エミュレーターではキータッチは再現できません。マニアしか買いませんよね。故障したら修理できるのかなぁ？

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.

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.

Calcolatrice certamente di elevato costo (la qualità vedremo se è paragonabile al passato), anche troppo. Disolito il punto debole sono i tasti ed è presto per dirlo, però si spera che l'iniziativa continui e che la bustina (dato il costo elevato) sia di pelle vera oppure che si renda disponibile after-market. Ormai pochissime calcolatrici adottano la logica RPN, che però consiglio a tutti, essendo educativa del pensiero tecnico e scientifico oltre ad essere ottima per allenarsi a comprendere alla sequenza di calcolo ottimale. Unico miglioramento atteso: prezzo un po' troppo elevato.
