Launch year

Calculators launched 1995 or later

The modern HPs and the reissues: the 12C Platinum of 2003, its 2006 25th Anniversary Edition and the 2008 Prestige, then the 15C Limited Edition of 2011 and the Collector's Edition of 2023, made by HP's licensees. They run on CR2032 coin cells and use newer processors, so they're much faster than the originals they copy. Several are still sold new, so a used one should cost less than new, and a reissue should never be sold as an original.
