The Investor Plus premiered at a trade show in late 1993. Read a 1994 product announcement here. It's designed to facilitate rapid financial analysis and is able to perform date arithmetic as well as cash flow and depreciation calculations. A sister calculator, the Pocket Appraiser, swaps out the trust deed keys (row 3) for three keys dedicated to appraisal functions.
