The Pattern Storage is a device that is used to either import or export information from memory crystals.
The pattern storage is mainly used together with a replicator. It must be placed beside the replicator for it to work. Its main purpose is to store information and allow players to cycle through patterns in a replicator. You may also place a pattern storage beside a scanner so that the pattern storage will keep the information. Note that a pattern storage does not require any EU.
Import or Export Data via Memory Crystals
Important: You need a memory crystal for importing and exporting data!
Right-click on the pattern storage to access it. There will be 4 arrows showing in its interface. The right and left arrows are to cycle between patterns. The down arrow copies data on the crystal to the storage. The down button will be coping data from its storage to the crystal memory placed.
