If there is no window on it and it's just a black chip with the game numbers, it's a 9316.
You can avoid changing jumpers if you have an eprom burner, u2 from nugent would go into u1 on the mpu200, u6 from nugent would go into u5 on the mpu200, and you'd put a copy of u6 into u6. That's if your mpu200 is currently set up for 4x2716. If it's set for 2x2732, you'd burn nugent u1 for u2, and double up u6 to burn into a 2732 for u6.
