via the seller: "I am selling this as non-working unit.It powers up.I think the problem is with the internal clock not working.There is a guy on You Tube who talks about this problem [possibly here, here, or here]. You can manually step through the events.All switches seam to be working .I don't have an analog keyboard anymore,so I can't input any notes or play anything out.I've taken a few pictures showing different numbers and lights on the display.These units are very rare..There were only less than 500 made.Mine is SN 072 .I also have the start/stop foot switch.This unit is also made for the US market (110v).Unlike the other unit listed from Japan that needs a power converter.I was the only owner.It sat in my smoke free personal studio for years.Then it was packed away.I might even have a photo copy of the circuit diagram somewhere that I will include if I find it.There is some scratches and nicks.But for as old as it is ,it's in good shape.No broken switches.All LED's light up.
