What's New
• If "Enhancements" are set to "Off", loading an empty card will blink "0.00" and program memory will be cleared to NOPs, like on a real HP-65.
• Some fonts have been changed from Courier to Menlo for better legibility.
• Screens "Paper Tape Printer", "Program Usage", and "Program Description" may be dismissed by dragging them down, in addition to swiping them horizontally.
App Description
World's first pocket computer! Now running on your iPhone.
RPN-65 SD is the iPhone version of RPN-65 Pro, the first complete simulation of Hewlett-Packard's stunning HP-65 programmable calculator for iOS. Produced from 1974 to 1977 at an initial price of $795 (that's close to $5,000 today!), the HP-65 was a breakthrough. Not only was it programmable, it also contained a motorized magnetic card reader - and still fit into Bill Hewlett's shirt pocket.
Experience this revolutionary calculator on your iPhone. With over 180 original HP programs included with the app, you can get started right away.
