Williams WPC95 MPU Alkaline Corrosion and ASIC Pin Repair Start to Finish

Chris Hibler walks through a full repair of a Williams WPC95 MPU board damaged by alkaline battery corrosion from a leaky battery, documenting the cutting, desoldering, sanding, and cleanup process. He also attempts a risky repair of a broken ASIC leg by grinding into the chip carrier and scabbing on a resistor leg, which he reports as working on the bench. The video is a detailed hands-on electronics repair tutorial rather than industry news.
