   That's not additional power, it's a set of signals.  On the SS2 
schematic, that connector is referred to as the "hypothetical memory 
expansion connector", and carries some select lines and I believe an 
additional address bit.

   I don't recall if the SS1/SS1+ motherboard has this connector or not.
