Recommended Posts

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
