I picked this thing up a few days ago and found that the foil/cardboard backing had shorted the back of the board. The arrows in the pic point to the visibly bad chips, the board was shorted behind the far right arrow. Im having trouble finding info on it as far as where to buy chips and identifying them. I have 3 visibly bad/burnt chips and can read 2 of them but the one circled in blue is not readable. Top left arrow is a SN74LS393N 14 pin, far right is a 74LS244N 20 pin, and the bottom is un readable 16 pin. What are these, what do they do? Can I buy these anywhere or are they game specific? What are the chances of having something else burned out that Im not seeing? Thanks for any info you can give!
