>First thing to do it opening it up and see if it *is* a battery issue.


Chances are it *is* a battery issue if it has been sitting for years unused. I couldn't get the pictures to load (I assume they were pictures from the filesize) but most older synths that were not used often and maintained properly will have issues with NiCd batteries. Assume the worst, hope for the best. Even if the battery has not outgassed yet, it may be damaged from sitting with no charge on it. In some cases NiCd's will internally reverse polarity, preventing them from taking a charge. So the presets are lost and the memory may in a "scrambled" state.

Bottom line: If no acid damage, replace the battery and try to load the factory presets via the tape input. If the display doesn't say "tape" when the tape input is enabled, the cpu bd isn't running correctly. Same for attempting to program a preset from scratch if the parameters/function selects don't display.
