Circuit boards

Usually mass production PCB assembly techniques, under each part is a drop 
of "crazy glue" like adhesive to hold the bit in place during wavesoldeing. 
If you have a PCB that you don't care about try acetone to dissolve the 
potting compound. Usually after the pins are desoldered, a careful 
application of force will crack the adhesive loose.

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
