I have Lost my HP15cL!!
This week I was traveling on a business trip to Norway. Many nice things - but somehow I managed to lose my trusty HP15c LE. It belonged to the initial American shipment, with serial number 182. The ones I have been selling were in the 23k range already.
Now, although I carry the HP15c in my jacket pocket all the time, it is with the HP41CL how I perform most of my financial work. But I had the HP15C LE programmed with all kind of financial programs (you can see previous installments of this blog to see a description of these programs. I have developed a version for the HP41CL for those that happen not to be in one of the zillion modules it comes with.)
The good thing is that I kept 5 units more in reserve. My thought was: “one for me, two for each of my two children”. Maybe they will be more attracted to the new HP Prime… In any case, I will have to spend significant time in writing all the programs back into the machine. But it is worth it: in board meetings, we can compare return rates for projects immediately - much shorter than the time it takes to open excel and test some hypothesis. And there is no way you can come into the boardroom with the whole HP41CL shebang, showing yourself a little bit as a luddite. (if only they knew that they are looking at the best current scientific calculator available…)
I have some hints about where I may have lost it. I will try to find out tomorrow, but the chances are slim...
Fortunately I did not lose my original HP15c, which has the exact same programs in.
On the other hand, I will have the guilty pleasure of opening again a new calculator - even though I did it already in the past.
