[Elecraft] RPN Calc App For Android

[Clark Macaulay]

Oh my, Bill.  You're dating yourself...as am I.

I worked for HP in the early 70's when they were the calculator king. Part
of the HP folklore is how HP got into the calculator business which is
fascinating.  I remember seeing a T-shirt with three symbols on it:  Enter
> =.  It took me a while to figure that out, and to this day I really don't
like algebraic calculators.  My 1st unit was a 12C and a 41C, both of which
I still have.  Oh, I still have my K&E Log Log Duplex Decitrig slide rule
with mahogany rails.  Yup....I'm old.

Downloaded the 42C app on the iphone.  I feel at home again.
