The MSAM/TopHat program of anisotropy measurements

An apparatus of the type having a display panel with game feature carriers and other indicating devices is provided in which the display panel is formed as a liquid crystal display. Circuit means are provided for selectively controlling the elements of the liquid crystal display so that three modes of control are employed, the display being different in each of the three modes. In one mode, certain of the display devices are continuously sequentially operated, and in a second mode a random control of certain display devices is provided, the last occurring indication in the second mode being held in the third mode of operation.
