Description

A dream calculator of the 70's, priced at $4,200 in today's dollars (2024), right on your iPhone!
RPN-67 SD is the iPhone version of RPN-67 Pro, the first complete simulation of Hewlett-Packard's legendary HP-67 programmable calculator for the iPad. Produced from 1976 to 1982, the HP-67 was a huge success among scientists, engineers and other professionals. Thousands of programs were written for it. Now you can run them right on your iPhone, with more ease and faster than ever before. To get you started quickly, run the built-in program cards, or choose from the large number of programs available as free downloads from our website.

RPN-67 SD Reviews

Fácil de Programar

Perloni on

Cinco estrelas e muito mais para este aplicativo. A calculadora hp-67 original perde muito para este emulador que agregou vários recursos do iPhone e expandiu sua capacidade funcional, além de eliminar certas limitações operacionais da original. No campo de programação, a RPN-67 SD dá um show, melhor, um curso partindo do básico ao avançado. Claro, você pode também desenvolver seus próprios programas, além de tantos que já acompanham o emulador. 150 no momento, mais um monte no Site do desenvolver (seção: What’s new), que deve ser explorado para aproveitamento máximo do aplicativo. Quanto ao preço, comparando com o modelo original, este emulador está de graça. Ah, qualquer dúvida a respeito do seu funcionamento, Willy Kunz, do suporte, estará pronto para responder. Já testei e fui bem atendido. RPN-67 SD para iPhone tem quase todas as funções da RPN-67 Pro ou RPN-97 Pro para iPad. Para iPad eu indico a 97 Pro. O que difere a SD das outras é complemento adicional da RPN a menos que não afeta sua funcionalidade como calculadora. NP não é programável, evite. Recomendo, ótimo aplicativo !

Excelente

Incredibly well implemented.

Very good, but found a math error

I used a HP-67 for years and loved it. This app makes me feel at home. However, I recently found a small, but significant math error. With the display set to 2 decimal places, enter the number 28,361.48. When entered, the number rounds to 28,361.50. I was doing a financial calc and this was the error. Update! Problem fixed! The Developer said it was caused by a precision change in IOS.

Love this app

Excellent simulation of the calculator I had in college. Wish there was a Hp 97 version for the iPhone.

I owned a 67

Good replica of 67. I have one issue that could be quickly solved. When I press the f or g key and then the display key, and enter a 4, the number of digits does not change from 2 to 4 and I would be happy.

Best RPN calculator

This was my first scientific calculator in real life. It is great to have the simulator on my iPhone. The special features added make it into a HP-41 or 42S! It comes packaged with some great samples. Am having great fun with it.

Really cool throwback.

My first HP calculator was an HP 29. A few years later, I got an HP 67. Later I bought a 15C and when I started an MBA program i got a 12c. It means a lot to have a really faithful representation of my old friend. I currently have this emulator plus a 12c and 15c (from different a vendor) on my iPhone. I love them all. Take it from somebody who know, all the emulators replicate their real world counterparts.

Works, Looks, and Feels Just Like a Real HP-67 Scientific Calculator

The HP 67 was my second HP calculator. I got it right out of college and used it heavily at work. It has long since demised. This is such s faithful replication. I really love it. It seems to be accurate and the next best thing to having a physical calculator in your hand. Thanks to the author for this product.
