2015's calculator anniversary - the SR-52

[jebem]

Thanks for bringing this Texas landmark into the light, Gene.

I have been looking to acquire a SR-52 since at least one year ago, but failed so far.
As a result, I have acquired the easier to find TI-59 and a few ones more from this TI-5x series.
Well, I can't quit this quest, so let me go back to the auction sites...
