RE: Found these inside a non-working 71B
It looks like you have 8 sequential connections starting from the left there should only be 7 the 8th wire will be connecting Din on U9 to Din on one of the 32Ks that will mean that when Din goes high there both modules will try to talk at the same time resulting in chaos and likely neither module being configured, you want to remove that wire and the one you picked up under the resistor should go to Din on the 32K that has Dout wired to Din on the other 32K you don't need to connect Dout on the second one to anything.
