This card is designed for use with the A1000 and gives it 2MB of CHIP RAM. It also has ROM sockets allowing you to use various kickstarts up to OS 3.1 without having to use a kickstart disk. Plus into the sockets of the custom chipset and possibly replaces the daughterboard. It also connects to the boot rom sockets, probably by a ribbon cable. Also provides a video slot for the use of video flickers and similar.
