Matt,

    I believe that AE RAMWorks III has RGB card which it is used for Apple 
IIgs monitor because it supports 4 bits in R, G, and B, but Apple //e RGB 
Card supports only one bit in R, G, and B including I (RGBI).  It will not 
work on Apple IIgs monitor, but it requires to use AppleColor M100 or CGA 
monitor.
