Never use a TMS2716 EPROM

The Texas Instruments TMS2716 needs -5, +5 and 12 V and is not pin compatible with a standard 2716, so it will not work in any Bally or Stern MPU or sound board (and most programmers cannot burn it). The TMS2516 is fine.

Systems

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