[BC] RPN

[Bruce Doerle]

I too started using an HP-35 when I was working for US Secret Service in Technical Development back in 1973.  I have been using HP calculators since I have not been able to grasp the algebraic "notation".  I love RPN.  I have a 15c and two 48SXs with EEAP and the PIM in one and additional memory and I believe the equation library in the other (it's at work).  I also have the infrared printer and the Program Development Link.  Fortunately, I have the manuals for the 48s and their accessories, but I lost the 15c manual when evacuated from Liberia along with the HP-11c.  I don't use the them much any more since MS Excel does just about everything I need now.   But I can't get use to working with algebraic calculator, RPN is ingrained in my head!

Any of you guys been watching the tower go up in Deland, Florida.  This is a Stainless tower and it replaces the one that a tornado took down earlier this year to Cox 94.5 Start Radio.   Hark Tower Systems has a webcam looking at the construction the 1500 foot tower.  They just began yesterday.  The link to the camera is through Wireless Estimator.  They have the gin pole up today.

I moved from the slide rule to an HP35 in 1972. I still have the 35, but
it needs some work. Day to day, I use an HP15C (I think that's the
number). RPN makes sense. My students that have calculators with algebraic
entry are always getting the order of calculation wrong, and they don't
know it. They just have "the answer" to whatever it was that they keyed
in.

Remember the HP t-shirts that had [enter] > = ?
