Hi Jose,

Looks like the 8080 should have the 680603 UUT cable, so the 604769s 
cables must be for some other pod (unknown to me). If you pull them off 
you can see if you can identify what pins are tied together, these are 
the grounded pins and may guide you to figuring out which pod they are 
actually for...

I've updated my Fluke sales page on flippers with this info - check the 
bottom of the page:
