It is a very crude machine. One of the sounds fires every clock pulse, no matter what rhythm you select, etc.. Also sold as the Arista Drummer Model SM200. Cost about AU$25 new. The chip inside has had its number removed, though the circuit diagram supplied lists a TTL chip, which frankly wouldn't work as described.
