About the Realbreakout PCB
Realbreakout is an open source PCB design by bradshjg, published on GitHub. It is a 2-layer board measuring 99.6 × 88.7 mm, with 22 components from 17 distinct parts.
Other key parts include the nescartheader, piheader, nescic, CD74FCT245 and MC74VHCT50A. By type, the board carries 12 connectors and 6 ICs.
From the project
Unsynced mirror of https://sourceforge.net/projects/tom7misc/ (I think that's called a backup)...but it's git now :-)
This is software, content, and hardware schematics for my project called "PPUppy," which I used to give a few talks in 2018 and a Youtube video called something like "Reverse emulating the NES to give it SUPER POWERS!" (also, a long "Making Of" exegesis).
There's a hodgepodge of different licenses in here.
In images/ there are some items for which I don't own the copyright, but which I believe are covered by fair use. (In particular, the size of the excerpt is very small):
