When these satellite boards give me problems I normally replace them with a single 27128 Eprom with level II basic on it and get rid of all the clutter related to the original setup.
Having said that, I have many of these satellite boards lying around... So the wires should go:
Red Orange Green Yellow (L-R on the 4 pads under the 74LS42)
Black and White (which are GND and power, respectively) L-R on the 2 pads above the 74LS42.
Hope this helps,
Ian.
