One of the connectors for the cable which joins the logic board to
the analog board has a bad solder joint on Pin 1. It's the
connector on the analog board. This is an extremely common problem
on the old 512 and similar Macs. There's an extra screw in the
battery compartment for five total. Once you have the case open,
just remove the cardboard cover from the analog board, identify the
pin in question and rehabilitate the solder joint.
Unfortunately, I don't know anything about the Thunderscan. I saw
them back when, but never had one.
