Quoted from Edster:I tried my first attempt at adding a socket and installing an NVRAM chip today. I started with my Fish Tales game. I carefully as I could removed the old chip without damaging any pads. I installed the socket and put in the NVRAM chip. Everything looked great. Reinstalled the CPU board in the game and now it won't turn on. The display is all wonky, and a few solenoids are firing. I quickly turned it off. I checked all my connections and tried a different chip. No luck. Could I have fried the game Rom? I used an iron and solder wick to remove. I did not remove the game Rom, i'm thinking I maybe should have.
Traces at the topside above RAM footprint pin 1 look damaged, same for the trace below pin 14 and 15.
