LET ME CLARIFY A LITTLE BIT...
Ooops, caps....
This NSS unit is NOT in working condition. It took a severe amount of force to get it removed from it's original position. It is pretty damaged and would definitely not be good as a spare, unless you want it as a paper weight.
Someone here on the board was looking for any and all used/damaged/disfigured units to poke around in and he had some sort of experiment in mind.
