Thank you for the replies. Well I did put it through the dish washer, twice, and still the same results. I let it dry out fully in the sun for eight hours before I tested it. I think the board is toast unfortunately.

But also, I did remove the FPU chip and put it in the LC iii. It worked perfectly, easy to remove and popped right into the socket of the LC iii. It for sure makes a difference in the speed of the machine.
