The schematic I made is based from an oztules gerber files and some 'the backshed' forum notes. Reference designators Rx, Cx, Jx, etc. are created by the schematic software I used. They are not present on the silkscreen gerbers. I think there is a later PCB design by oztules.
I think J9 is the 3 pins pwr on/off. I checked for J5 and I could not find it but I think oztules mentioned that if you want hard reset, connect that end of the 120 ohms resistor to ground, So I just added J5 for that.
