The HP 65 calculator was an amazing piece of technology for its time in the 1970’s and still highly valued among collectors today. A highly reguarded piece of engineering that NASA used on space missions in the 70’s as well. At the time real computer time was expensive at Universities and required keypunch cards,that had to be turned into computer data processing center to see if they would run and to retrieve a large print out, very time consuming. The HP65 was handheld had a magnetic card reader built in that allowed the user’s to write programs up to 100 steps or use preprogrammed magnetic card programs.
