The video chip is a WD 90c30 9144A(1991).Would anybody have a book for the motherboard( jumper settings),or a number for Tandon? I have searched and found nothing. The last number I have for them is 805-523-0340. Absolutely any help would be much appreciated as obtaining reliable information in Greece is extremely difficult. P.S I know that this is only slightly PIC related so email direct may be appropriate Many thanks -- Peter Cousens email: peter@cousens.her.forthnet.gr snailmail: Peter Cousens, karteros, Heraklion, Crete, 75100, Greece,
