It is a memory pattern "test". You recieve 4 memory pattern test cards.
There are several different common memories on the cards.
The spec has a free choice of one of the memories.
You are then able to go into detail and describe the memory they have chosen and additional details surrounding the memory.
Hey, for $15.00 bucks it plays pretty darn strong.

By the way, there is a large thread on Kioku on this forum.
