The logo and text are completely wrong, and the date code is nonsense, which is evidence of remarking. The chip has two ejector pin markings and a notch, but does not match any known Yamaha YM2612 package styles. The key point to notice here is that the notch is shallow, and does not go all the way through the chip. It's not even worth testing these chips in-circuit. **Fake.** Aidan Lawrence has identified many of these fake chips as actually being 6116 SRAMs. |
