From p. 2 of the RAMLink manual:   
      
   RAMLink contains an internal connector for adding RAMCard, which is a   
   'daughter board' that allows you to easily expand the RAM capacity of RAMLink   
   up to a maximum of 16 Megabytes. RAMLink may contain only one RAM Card, which   
   in tum may hold up to four    
   SIMM modules mounted in sockets on RAMCard. The SIMM modules may be 1 or 4   
   Megabyte versions, but mixing of these two types is not generally allowed (see   
   'SIMMs'). When using RAMLink with an internal RAMCard, the memory found on the   
   card may be either    
   combined with the memory found in an external RAM expander (Commodore REU,   
   Berkeley GEORAM or CMD RAMDrive), or these may be utilized as separate   
   entities.
