While looking in to the backbox pondering over how to set up a external battery box without doing any soldering on to the card itself I realized that there are a chip holder with out a chip. Is there a missing chip (if so what?) or is the board just prepared for something that never ended up in use at the LW3 game?

Btw. It should work replacing the batteries with two 'false' ones in wood (upper and lower) with a soldered ground on the left hand side on the lower and a soldered hot at the right hand side on the top, leaving the middle slot empty. The other ends of the new wires would go to respective place on an external battery box? Or any issues with that 'solution'?

Thanx for reading

Thanx for the tip. Funny though, that is EXACTLY what i had in mind of building me, with the difference wood instead of plastic. Interesting that i had the same conceptual idea without ever seeing that solution before. I'll post a pic when i am finished with my 'build'

I got around to make my external battery box. My idea worked like a charm.
A piece of wood, some cables, a battery-box, a few screws and a tad of soldering later this is what I came up with.

Thanx, I figured that I wanted to do cheap and easilly reverted external battery box configuration. If for some reason
the next owner would want the pin back in its original condition. Or if the external battery box over time will fail, then it is an easy replacement.
