The HP-45 was the second scientific calculator introduced by Hewlett-Packard, adding to the features of the HP-35. Especially noteworthy was its pioneering addition of a shift key that gave the other keys alternate functions.
The calculator was code-named Wizard,[1] which is the first known use of a code name for a calculator. It also contained an Easter egg that allowed users to access a not-especially accurate stopwatch mode. An accurate version of this stop-watch mode was in 1975 officially featured in the successor of the HP-45; the HP-55.
