ROM types that share a jumper setting are not interchangeable between games

2532, 9332 and 8332 parts all use one jumper setting, and 9316, 8316 and 8516 use another. The code inside is still game-specific, so a U2 chip from one game will not run another game even when the chip type matches.

Systems

• Bally MPU AS-2518-17
• Bally MPU AS-2518-35
• Stern MPU-100
• Stern MPU-200
