Now, on to the next lesson. This does not always upgrade boards. Please keep this in mind. Try to scrap the other half still, besides discarding into the trash. This is another reason we frown on cutting boards to upgrade because most of the other halves are discarded or not attempted to be recycled having little to no value left.
We want to make money, get paid, catch a little precious metals, but also keep this stuff out the landfills.

Posting like you did with comments and concerns about upgrading anything in mind is the best option for anyone, even the top dawgs; we don't know everything. Not even BS has seen everything!

I would still scrap the bottom half. It would just go to my normal pile of shredable materials at my local scrap yard. I can't find anyone local that will buy the circuit boards. Not sure the remaining board is worth shipping.
