RPN-65 SD 3.9

Introducing RPN-65 SD, the innovative iPhone adaptation of the RPN-65 Pro, a remarkable simulation of Hewlett-Packard's iconic HP-65 programmable calculator designed for iOS. Originally available from 1974 to 1977 with a hefty price tag of $795 (close to $5,000 in today's currency), the HP-65 made waves in the industry. Beyond its programmability, it boasted a motorized magnetic card reader while maintaining a pocket-sized form that could be snugly carried in Bill Hewlett's shirt pocket.
