NullCIC

A little board to replace the CIC on the original NES or OpenTendo, and restore reset functionality.

All the files needed to make your own are located under the releases section.

You can also do the same thing the NullCIC does manually, just check "Reset fix without NullCIC.jpg"

Questions

How big is the NullCIC PCB?

It measures 10.8 × 21.8 mm and has 2 copper layers, 1.6 mm thick.

What parts does the NullCIC use?

4 parts, built around the 74LVC1GU04DRL. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the NullCIC KiCad files?

From the Redherring32/NullCIC repository on GitHub, at the commit this page was made from: the board is Board Files/NullCIC.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the NullCIC design in my own project?

Its repository states no licence, so its author keeps all rights: ask Redherring32 before reusing the design.
