Hello everybody.

I am looking for schematics of this board, my goal is to restore an Galactica Batalha Espacial (game made by Taito of Brazil), a few months ago I ported a driver to MAME, but the sounds are still imperfect, and I believe the timing too.

I have found some manuals on the Internet yet they are with low quality and can not read a lot of information, not to mention that some copies of the pinning of the connectors are not hitting with schematics presented.

The boards are models PVN00003, PVN00004 and PVN00005.

Thank you for collaboration.
 
Hi EclipseEye,

I know this site, and others too, all of them have the same scan, with a poor quality.

I need a rescan with a better quality or a remade like Williams L shape.

Thanks.
