Hardware Description

The HP-92 was HP's second battery powered printing calculator. It was the business/financial model of the series and featured an improved Time Value of Money solver that could compute any of the basic five financial values given four known values. (For many problems, only three known values were needed.) It also provided depreciation using declining balance, straight line, or sum-of-the-years-digits methods and accounted for book value and salvage value.
