## RPN-35 SD Description
Am 4. Januar 1972 stellte Hewlett-Packard den HP-35 vor, den ersten wissenschaftlichen Taschenrechner der Welt, der so klein war, dass er in eine Tasche passte - genauer gesagt, in Bill Hewletts Hemdtasche. Der HP-35 war sofort ein Hit bei Studenten, Ingenieuren und Wissenschaftlern. Trotz seines hohen Preises von 395 Dollar (heute etwa 3000 Dollar) verkaufte er sich im ersten Jahr zehnmal besser als erwartet.

Erleben Sie diesen einzigartigen Rechner, der HP im Jahr 2009 den prestigeträchtigen Titel „IEEE Milestone in Electrical Engineering and Computing“ gewann.


Merkmale:

- Fotorealistisches Look-and-Feel
- Drei Skins: Version 1, Versionen 2 & 3 (1973) und endgültige Version 4 (1974)
- Vintage-Modus und Erweiterter Modus
- Tastenklick und Tastenaufleuchten, beides optional
- Wischen nach links über die Anzeige zur Korrektur von Zahleneingabefehlern
- Ausschneiden/Kopieren/Einfügen von Anzeigewerten
- Anzeige von Stapelregistern und Speicherregistern
- Alle Dezimalpunkte bis auf einen leuchten, wenn die Batterieladung des iPhones unter 5 % sinkt.


Vintage-Betriebsart
In diesem Modus werden die Eigenheiten einer echten HP-35 simuliert:
- Ursprüngliche Arbeitsgeschwindigkeit
- Stapelregister Z wird bei trigonometrischen Funktionen nach T kopiert
- Führende Nullen können eingegeben werden; Nullen können negativ gemacht werden
- Eine negative Zahl kann durch Drücken von CHS vor oder nach der Zahl eingegeben werden
- Eine Tastatureingabe oder RCL unmittelbar nach STO hebt den Stack nicht an
- Nur für Version 1: Simulation einer Reihe von bekannten arithmetischen Fehlern

Erweiterte Betriebsart
- Nichtflüchtiger Stack und Register
- Verwendung der Register 1 bis 9 mit HP-45-ähnlicher Registerarithmetik
- Register 0 arbeitet als LastX-Register
