Williams FirePower 2 MPU and Driver Board Repair and Test
Williams FirePower 2 MPU and Driver Board Repair and Test I rendered the still images in the wrong order. The last image is the "before pic". The preceding images are steps along the way. As is often the case, leaky alkaline batteries damaged this System 7 MPU and the driver board. Argh. Those days are long gone now. NVRAM to the rescue again. All headers replaced. But why can't you just reflow the headers you might ask? The round OEM pins wore out long ago. Williams sheered them too close to the PCB, and over time, they work their way out to the front of the board. Attempting to reflow those pins results in "zits" that don't hold up.
