VINTAGE HP 15C SCIENTIFIC CALCULATOR WITH ORIGINAL SLIP COVER AND MANUAL

May 12, 2018

Iconic engineering calculator

Etched on a component substrate made of saphire, it got extremely power efficient and durable. A real gem in both senses of this word. In many opinions the optimal hands-on calculator for a truly real engineer. Probaly much to costly to remake today. And You need to use Reverse Polish Notation to program this iconic gem - a positive extra feature for many hardy numberofilists

impressive

Well designed, functional and fun to use. This was made before Dell and Compaq interfered with HP - totally destroying its engineering exellency and good name. Some of the best qualitative engineered trinkets of all time :)
