4th example into the YouTube video above for the HP Prime (11-i)(2+3i) = 25+31i the print is so small the 31 is written as a 3. |

I use the SwissMicros DM42, or, if I'm removed from it, the hp42 emulator on my phone. Or if I'm on a real computer, "dc". |

A good thing to know the basics, at least... --- End quote --- Here's a sharper picture. I seem to have irresistibly bought more than one of these, since it boggles the mind how such a device can be made and sold for $1. Partly for nostalgia reasons, as I remember a calculator of similar specification in 1978 would have cost about $100 in today's money (say $20 - $25 back then). Edit: I think, if you take one apart, you find that the circuit board is made of laminated card, and the tracks going to the keys are printed in some kind of graphite material. Not that I want to destroy such a valuable item by taking one apart myself :) |

So the HP Prime runs for 25 hours on a custom lithium-ion battery, and barely supports RPN? That is no better than a PDA, no thanks. |
