Hey everybody!
We've got a Tales From The Crypt machine that we've been working on, and we have a question. Someone had wired an arcade cab power supply to the psb before we got it. We turned it on and smoke rolled out of the back box. We removed the extra power supply, same thing. We ordered a rotten dog replacement board. It came without any kind of documentation. We put it in, connected all cables, turned it on, and smoke again. We ordered a second board, but have been hesitant to install it. I haven't found any documentation, but there are a six spots that look like contact points to which additional components could, or perhaps should, be soldered. Anyone got an idea?

It was this particular board. We turned off the power the second we smelled smoke, and i honestly can't see where it began to burn. I'll see if i can find the pictures our other repair guy took.
