Sure, but the new LCD didn't exist 20 years ago, and I assume was built with expectations of newer applications. So maybe that's where the need for changes comes from. I dunno, we'll likely never see a real circuit diagram anyway. 🤷 |

The only thing that might have changed is the TTL level, from the former 5V to 3.3V. I'll figure it out, I'm afraid.... ;) Good night. |

Thank you, but I don't know how to make any sense of that without a schematic. Even still, it might be above my paygrade. 😉 R1 - R6 are all mostly interacting with the LM324 chip, and then some tantalum capacitors. What happens after that, I dunno. |
