I'm working on an art piece involving the NES-001 schematics, and I'm having trouble finding a correct version of it. Each one seems to have different deficiencies.

So far I have found:
Console5 , which has some obvious incorrect connections in regards to pin 65/37 on the cartridge connector (clock line connected to an address line) It's also hard to read many of the labels, making it even harder to use.
Famicom - Which is useful, but obviously the famicom and NES cartridge connectors are different, and the lack of the extension port does not help.
Hackaday.io - Missing most of the support circuits, but otherwise appears correct for IC to IC connections.

Are there any versions I'm missing, or other definitive versions that people reference?


For those curious, I'm working on making something similar for the NES - to this one I did for the Commodore 64. I'm making a new schematic from scratch for this piece that avoids named nets, hence realizing the issues with the other schematics.

Definitive? No, but I have been occasionally working on fixing the Electronix Corp reverse-engineered schematic that's on console5, here

Thanks - that one is definitely better :)

I have a feeling I need to buy an NES-001, and check the nets myself... All I have right now is a top-loader.

I haven't noticed anything else obviously wrong with the existing schematic.

Uh, ok, there's a few pin numbers that are wrong but you said you were going to remove them anyway.

Did I just help you find more issues with it? Yay :)

I'm keeping the pin numbers, I'm just trying to avoid named nets in the diagram I'm doing. I like seeing real traces going from chip to chip.

Not so much "find more issues" but "provide a kick in the pants to upload the corrections I made two months ago"
