Day in Tech History

HP41c Programmable Calculator

Hewlett Packard came out with their first Programmable calculator in 1979. The HP-41c was the first to give alphanumeric display capabilities. It would actually tell you what to do (ex. “ENTER RADIUS”) instead of leaving your wondering. It also had four ports that could be used to expand memory, install a Thermal printer, magnetic reader or bar code scanner.
