What version of AppleWorks is it? If I recall, later versions have the appropriate support for RAM cards built in, but 2.x needs to be patched. All my Applied Engineering memory products with Appleworks support have come with a disk called "AE AW3 Expander" to patch and add support for their cards. Disk images are readily available online.
