Files of this type and auxiliary type contain images of Apple IIgs Battery RAM.
Since the IIgs battery-powered RAM contains important system parameters and control information, many utility programs would like to save an image of all these parameters for later restoration. This ability can be handy when changing batteries or in a classroom situation where students may change text colors and preferences to suit their individual tastes -- without regard for the teacher who has to restore the machine to normal operation for the next class.
Apple has defined the following simple file format for use in such instances.
The file format contains a safety catch to prevent parameters defined for new machines from interfering with older machines.
