When GURU is launched it displays a floating palette like the one shown below. This palette is composed of a dozen and a half pop-up menus. Each pop-up represents a family, or group, of computers.

To determine your next memory upgrade simply choose the family which contains the computer you are interested in. Click, and hold, on the pop-up family. A list will appear which contains all members of that family. Slide the mouse to the desired machine and release the button. You will immediately be presented with the main information screen. The screen shot below illustrates some of the configurations possible for the 7500/100.
