Your First Handheld?

[Jim Horn]

First calculator? HP-25 at its introduction, July 1975, shortly after graduating as the only member of my university class without a calculator (I was waiting for an affordable *programmable* one).

A year later, got an HP-67 at its introduction; the '25 went to my younger brother who studied the living daylights out of it (hello, Joe!). Then the '41 at its introduction, August 1979. Lots of different machines since. Now use '50g at work, WP 34S at home, Free42 on my S8 and Surface Pro 3 (along with Mathematica 10 on the latter). All have been my favorites - great systems! The '25 is in storage but I hope to dig it out and add the Bernhard's magnificent chip to get it running again. It's clicky keys, LEDs and today's batteries will make it a fine everyday machine!
