Ok here are pictures of work done so far.

The two wires are bridging tracks that were corroded away. Ones is going to the Sony sound chip and the other one to the Bournes filter (so nothing to do with my graphics problem).

One wire to fix the graphics problem. Ran out of wirewrap at that point hence the crooked wire, nah probably just too lazy...
SCSI still not working but I found two more faulty vias associated with the SCSI chip...everything else checked out OK.
Bed time now though |) , might have a go at it tomorrow.
