Here are some work intensive photo edits of where i think the traces go on the VIC Card
frontplane is blue, backplane is red
start by tracing power routing to every chip to verify.
also seems to me that pin 3 of the pll goes to the 10k resistor called point "G", the input of figure 5.
(because pin 4 of PLL- VCO signal out, goes to pin 14 of 4017, pin 14 is the clock input and i would suspect that according to the photo and according to the figure 7 schematic this would be true)
Basically signal goes out on pin 4 and comes back on pin 3 so if you switch in one of the 4017s the frequency is divided and comes back from pin12 carry to pin 3 pll and at this point goes to point "G"
if pll pin 4 went to point "G" the 4017 dividers wouldnt work...
also here is the multisim simulation for figures 3, 4 voltage circuit... still have to test it in the real world but its updated based on the VIC CARD revelations...
