DXC-151A and XC-117 Video Cameras

Anyone have any idea where I might find any data on two obsolete Sony
video cameras? The XC-117 has a daughtercard that plugs onto the back
with some mysterious 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: GND, VBS, VS, VG, 12V

The DXC-151A has several connectors, a round 12-pin, a DB-9, and a
squarish 4-pin that I have no clue about. Without a data***/pinout I
am lost. I have not worked with video cameras.

Thanks
