DEFENDER... I added a socket for the NVRAM and I have a question. *PHOTO ADDED*
Hey guys... I desoldered the 5101 Ram chip on my DEFENDER PCB and added a socket for the NVRAM daughter board. Im still pretty new at this stuff. My question is... when I went to solder in the socket , the feet are so close together some solder may have inadvertently touched together on a few of the feet. I tried my best to not let any solder dots touch and keep them seperate but I could see a few of the solder dots are really close to or are touching. When I plugged the game in and turned it on everything seems fine. The high score saves without the batteries and the game seems to play fine. Are the feet suppose to be isolated completely when soldering them??
Its a little hard to photograph but here is what Im trying to explain... some of my solder for the individual socket legs the solder dots are accidently touching since they are so darn close. Is that a problem? Should they all be isolated? When I powered up the game everything seemed fine. Im just not sure as Im still learning this stuff. Thanks

I tried looking at the schematic and found the 5101 chip. can you tell from the schematic and compare it to my soldering job and see if I accidentally let solder touch where I shouldn't have.
