The Clear Coating is Conformal coating. Check on unused corner of board and
see if the B12 carb cleaner will start it peeling. I used that on board I
used to repair. Also used the, I think name was Chemtool, stuff you soaked
carbs in to remove. As always, if carb cleaner says is dissolves plastic,
don't get in on thing you want to keep.

Failing that -- go to your nearest electronic supply store and get conformal
coat remover. (NOT radio shack:-)).

I have a couple of EEC_IV boards that I am trying to disassemble. The
CPU and ROM  seem to be glued down then sodered into place. There is
also a heavy, clear coating (waterproofing?) over everything.

Does anyone know what will disolve this without destroying the board?

How about the glue?

Thanks in Advance   Tom Sharpe
