Would someone mind please rehosting the 2nd edition files? I have a NWI modified MT-32 that I am going to try to document the modifications for the community but I would rather not have to figure out the schematics from scratch. TY!

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!

Thank you all for the scans of MT-32 service notes 1st & 2nd edition. They are very difficult to find.

I also sent it to console5 to host it and add it to the new Wiki they are putting together for the MT-32.

Link?

I know this is old now, but just in case it is needed, here is the direct link for the 1st edition notes at Console5.com:

Thank you! Downloaded and bookmarked!
