Attention Turbo3:
can you try and trace out some test pads connecting to the TV input and output pins on the northbridge??
Input:
U4, U3, V3, N01, P02, P03, P04, R01, R02, R03, R04, R05, T01, T02, T03, T04, T05, U01, U02
Output:
V2, U5, V1, V5, V4, W5, W2, W1, W4, Y3, Y4
with this info, we should be able to attach external encoder/decoders, and get TV in and out on our IOs soon to (hopefully have TFTs)
