     Since your non-working IIgs worked before it was put in storage, the
most likely reason it does not work now is that one or more socketed IC's
have some pins which are not making contact. There are several ways this can
happen-- pins 'ratchet up' due to changes in temperature and/or acquire a
corrosion coating, the storage container gets bumped around, ... .

     Before you swap in chips from your working IIgs, try pulling and
re-plugging the socketed chips in the non-working IIgs. Usually, this will
reestablish good contacts and fix problems.
