HP 65 programmable pocket calculator
The HP-65 was similar to the HP-35, HP’s first handheld scientific calculator, new features included a card reader, the slot to hold a card below the display and the second slider switch to select program or run modes. The HP-65 was HP’s fifth handheld electronic calculator. HP65 was nicknamed "Superstar", the HP-65 was the first magnetic card-programmable handheld calculator, which is why some call it the "world’s first handheld computer."
