Hi. You can have Hese probably fix this one for you. He has repaired two of these boards for me including one seen in autoconfig list but reporting error in Janus.library.
Most likely the repair underneath the battery is no good and the corrosion has gone deeper or one or both of the PC VLSI chips are dead (but can be replaced).
About repairs of bridgeboards I am sure that almost any fault in a goldengate board can be repaired and most of the problems of the A2386 can, but you need a qualified person with knowledge here, that means Hese.
 
The card was repaired several months ago. The following issues were addressed:

  • The battery had leaked on the card and had been repaired by the previous owner. However, two of the corroded vias near the battery had not been properly fixed. Although they still conducted, the multimeter showed excessive resistance. These two corroded vias were subsequently repaired.
  • The VL82C311-FC2 chip had several cold solder joints. Some of the pins were barely making contact with the pads and could be moved with a stick, which is not supposed to happen. It appeared that someone had reheated the chip with a hot air gun without adding new solder. The VL82C311-FC2 chip, along with the adjacent VL82C107-FC chip, were reflowed.
  • The U402 chip had a couple of cracked solder joints, with one of the legs no longer making contact with the pad. Both U402 and the adjacent U401 chip were reflowed.
