Solution 12644: Replacement For The Discontinued Business Edge Calculator.
What current calculator replaces the Business Edge?
Since the Business Edge was discontinued in 1990, Texas Instruments is no longer able to provide parts, accessories, or service for this unit. A comparable calculator to replace the Business Edge is the BA II Plus™ Professional
. However, none of TI's current financial models feature the Power Touch™ display keys that were used in the operation of the Business Edge.
