Ability Plus - A Windows Version?

A Windows Version?

In the early 1990s, some thought was given to making a Windows version of Ability Plus, but the difficulties in fashioning a Windows program from DOS code led to the decision to start from scratch. The outcome of this line of development was Ability Office, and although it shares no source code with the Ability Plus, an attempt was made to follow some of the design principles of the original such as shared code and a common recalculation engine.
