I have an old video camera that I would like to test, but I have no
clue how to do so. It has some sort of an interface board that plugs
onto the connector on the back of the camera body. The interface board
has the following;

CN-116

Numbered signal points;

8 W2
7 W1
6 Gain 2
5 Gain 1
4 AW IN
3 AW OUT
2 GND
1 5V

Other un-numbered points (scattered);

GND
VBS
VS
VG
12V

Chip on the board is marked:

T9143H / 45388F


Is this interface scheme in any way familiar to anyone?

Thanks,

Dave
