Condition:
For Parts or Not Working — Battery Corrosion.
This vintage motherboard has significant visible corrosion/leakage around the onboard Varta NiCd battery. The extent of any electrical or trace damage has not been determined.
The board has not been powered on or tested in its present condition, and I would absolutely NOT power this up before the battery damage is addressed.
Sold as-is for restoration, repair, parts or vintage computer collecting. Please review all photographs carefully for exact condition.
