So I'm once again going the MS route but this time I wanted to update the MS1 to an MS2 or MS3. But before I started modding, I wanted to better understand the MM9093. I could find the v3.57 main board schematics easily but for the life of me I couldn't find the schematics for the MM9093 daughter board. So I decided to the ohm out the board and create a schematic for my own use. Since I'm not the selfish type, I wanted to share it with the community. Give it a look see, let me know if I missed anything. Thanks.
I also included the schematic in PDF format. It makes searching for signals easier.
