G'day Rob -

Ooops... I think unscrewing the core mat cover voids the DG warrantee!

Sounds like 16KW DG Nova boards, and I would be glad to try to resurrect
them for possible use in a Nova 2, Nova 1200 or some other such system. Do
they appear to be in good mechanical shape; what about any obvious
electric/electronic damage...?
