MemoryChamber
Our original headmap, in 1986, had a "memory chamber" in the back, and we haven't been paying it any attention. Prior to that we had only a File Cabinet (previous to knowing consciously that we were multiple). Our first headmap shows this area as being completely full, overflowing, etc. We're currently working from a version of memory chamber that utilizes our file-cabinet as an interface for currently-accessible information that's not yet available. Deep storage-- the memory chamber -- would be harder to access, but the file cabinet interfaces with it.
