Business Analyst

I found this device cleaning out a file cabinet at the day job recently – a device dating back to my first year in business.  Back when America was supposedly great.

My trusty Texas Instruments business calculator.  Technically a Business Analyst-I.  Capable of calculating useful daily mathematical calculations such as square roots, reciprocals, percentage changes and basic arithmetic it was indispensable to a newbie financial guy who might need to calculate a yield to maturity on a bond, a discounted cash flow, a mortgage amortization, annuity or installment loan.  This state of the art electronic wizard even had a small brain capable of storing information briefly for recall and exchange capabilities.  

I found a nine volt battery and fired it up.  The bright red LED display was clear and the math was perfect. This vintage device still works like a charm.  Made in America by Texas Instruments Corporation – Dallas, TX.  The owner’s manual says that if it breaks I can send it to: 

Texas Instruments Service Facility   

PO Box 2500  

Lubbock, Texas  79408   

One year limited warranty doesn’t seem like much anymore.  It’s been 37 years since it expired…
