|Introduced on May 1 1973, this was the
third handheld electronic calculator sold by HP, and the
second scientific model. It built on the success of the
HP-35, adding many new features. Some were taken from the
HP-80, others were completely new, including the LAST X
command, numbered data registers, store and recall
register arithmetic, built-in conversion constants, and
selection of trigonometric modes (DEG, RAD, GRAD).
It is the first handheld known to
have had a code name - "Wizard". Early
models had a built-in timer
The HP-45 is a favourite
among collectors; especially HP-45s with the timer. There
was a large desktop version of the HP-45, with a built-in
printer, called the HP-46.
