The method of differential approximation of a time discrete difference scheme is used to derive ``semi-implicit'' approximations. This involves adding implicitly and subtracting explicitly some simple operator whose matrix form is easily inverted, and results in unconditional linear stability for much less work. An application to a system of equations is given.
