Sorry for resurrecting an old thread, but I have a KP-990 (which I love) and hopefully you guys can answer this question. Mine is functioning very well, but one problem it has is the ribbon cables have developed an oily, sticky film on the surface. I've seen this with other old plastics before so I'm not surprised, but does anyone know the specs on the ribbon cables? I'm wondering if it's possible to build new ones. At least some of them just plug on at both ends, so it'd be an easy replacement. Thanks.
