In case anyone's unfamiliar with this model, it's an old electric piano from around 1980/81. Four selectable sounds: bass and piano 1, 2 and 3. Chorus/phaser which is controllable via the sliders on the front. It was also velocity sensitive, which is rarely seen among this style of electric piano from this era.

Here's the entry from the Italian Crumar Museum (http://www.enricobassi.it/crumar.htm):

Anyway, that's just a little background; still looking for schems in case anyone has any or knows a source. :)
