The HP70 and it's limitations.
Have you ever tried to calculate the square root on an HP 70? First you realise "oh, there is no sqrt key!". Then you think "ah, there is y^x". So you type a 2 and go in search of thea 1/X key. But you can't find it. So you hit enter, 1, /, y^x and finally get a result. But oh no... you pushed something off the stack... then you start wondering:
Ok, admittedly the HP 70 was never intended for engineering use, maybe there is no need for sqrt. But 1/X?!? Is that really never needed by financial people?

Any thoughts? I am still wondering...

Cheers,
Harald
