    Buy a schematic on ebay and stop guessing it's only 3 dollars.

          heavymachines, took a look at e-bay for the schematic. This is all I could find 1 seller has this hannstar j mv 94-0 E89382 Quanta zy9. I need rev 2.0 hannstar mv-4 94v-0 E89382. The seller doesn't know if this it or not.

              The seller on e-bay e-mailed he said he has 2 different schematic's that might work he found on his data sheets. He's going to send them ,but he's not sure.

                gonna send them both? or one of the 2? i found one fella called chipmasters here in usa ...his listing says only one and it 3.99 per schematic... is all i find that looks half way legit...


                looks like the only one on all of ebay....

                    cool cheap enough...it will pay for itself just in its info it beholds about this mobo



                    too bad they aren't all free, should be ...see back in the olden days most of your electronics had them inside, in a holder everything you needed to know even crt tv's had em inside...nowadays its yeah right.....
