World's first pocket computer! Now running on your iPad.
RPN-65 Pro is 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 more 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 iPad. With 170 original HP programs included with RPN-65 Pro, you can get started right away.

• Backstepping from step 001 to 000 in modes UI and Plus is now supported. In addition, step 000 is labeled as "[TOP]".
• In vintage mode, typing "GTO.digit" and "LBL.digit" would not start a number entry.
• Also in vintage mode, single-stepping an instruction like LBL 5 would not be executed as on a real HP-65 when the mode switch was flipped to W/PRGM and back to RUN between steps "LBL" and "5".
