CASIO electronic keyboard (near Cabin John Village)

CASIO model 670 tone bank. It has an AC adapter. It's been in storage at least a decade, and at one point exposed to humidity. The keyboard is barely functioning, but the "beat" or rhythm (vamp) selections are mostly working. It's possible if the back is taken off and the contacts cleaned it could be restored. I'm not sure how realistic that is. Not something I'm interested in doing.
