The far right is GND. The connection you are pointing at would be B0.

I need to get home and look at it again.the broken wire might go to the 4th from left. Something else noticed in the photo. Pin 9 on RAM board looks a lityle brown. And the far right pin looks to have a bubble of solder at 71 board. mihgt have had a short at one time
