HP-45 Hewlet-Packard Scientific Calculator |
 |
| "Introduced on May 1 1973, this was the third handheld electronic calculator sold by HP, and the second scientific model...It is the first handheld known to have had a code name - "Wizard"... The HP-45 is a favourite among collectors; especially HP-45s with the timer." Wlodek Mier-Jedrzejowicz. | |
