Not much there other than the capacitor list for the rev1 that I sumbitted and the map of the capacitor locations. In fact they don't even have a direct link to this yet from their main Wiki pages and I had to search for it. Probably once there is more information Luke will get it more fleshed out.

OK, someone in this thread posted the 2nd edition but removed the link. I am looking for a schematic for the -01 revision PCB so I can see the changes of the NWI noise and PCM mods.

I do have the 2nd Edition of these notes from that link, but it's not particularly readable in some sections (to me, at least). However, I still regret not buying the physical copy of the 2nd Edition notes I saw on eBay a few years ago... Was about the same time I bought my own MT-32.

Perfect, yea they are rough but I should be able to get what I need. I’m going to attempt to make some schematics for the RWI mod. Thank you for the upload!
