My first calculator was a Sinclair Scientific (non-Programmable). It was very limited and not very accurate, but nonetheless it was better than a slide rule. Also, the manual, short as it was, showed several examples of practical engineering calculations, which gave me a first glimpse of what those mysterious trigs and logs could do (I was in 5th or 6th grade at the time!), and sparked an interest in mathematics that has stayed with me ever since.

About two years later, my dad bought me an HP-25, and oh yes, that was unbelievably cool and powerful by comparison.
