Hi Everyone,
Here is a now amusing scenerio, I bought several of the push in wire type plastic prototype boards over the last 15 or so years, and have been using them to test pic programs. Yesterday I threw together a serial LCD using one because I wanted to port over some code to a smaller pic, and the serial lcd gave me fits. I knew the code was good, and the pic was new, I messed around for hours. I removed the protoboard from it's backing plate and discovered corrosion directly underwhere my pic data out pins were - moved the whole mess to another proto board and all is as it should be.
