Schematic for Model 4 non gate array

[whaledriver]

I have a model 4 non gate array mainboard (REV C). I for the life of me cannot find a schematic for it. Does anyone have a copy or maybe a link to one. I am trying to bring this one back to life and I am stuck. All of the schematics out there are for the Gate array or the board with two crystals. Mine only has one (20.275mhz)

 

Thanks,

Sean

Thanks but unfortunately non of those documents have my main board. I have a REV C PAL board (1 crystal) and I am having a hard time finding the schematics for it.
