Pin37 sys-clk on cartridge connector unconnected? #5

Open bzuidgeest opened 1 week ago

While looking over the schematic and PCB I noticed that pin 37 net sys-clk seems unconnected. Am I just missing something, or is this an error?

Looking at the schematic, that pin is Labeled System-clock not sys-clk like the others.

Pin 37 is unconnected on the OEM board, and as such the pin should have been unlabeled or marked as NC in the schematic, but it seems I managed to forget doing that when I modified the OpenTendo schematic for this.

I'll try and fix it tonight, thank you for bringing this to my attention.

Are you sure? sites like https://www.nesdev.org/wiki/Cartridge_connector very much show it connected. Source all over the internet vary in if they show it connected or not. The schematics on nesdev do not, but I have seen it connected in others. To bad nintendo is such a closed company otherwise we could just ask them.

Thank you for looking in to it.
