via the seller/listing: "vintage lap organ / synthesizer / keyboard. This is from an estate clean out so little is know about it's history. There is no brand name I can find on it anywhere, but from fellow ebayers...most likely this is made by PAiA. It is in very good condition cosmetically, there is some yellowing of the keys but the case is in good shape, all latches work, the top folds up or can also be taken off. The inside looks very clean, I plugged it in but there is no speaker built into it so I have no idea if it works. There is no bulb in the "Power On" light so Im not sure if it is getting power or not. Im not sure what type of amp or speaker you plug it into because I dont see any input jacks, only the 3 small ones on the control panel. I do some some calculations written in pencil on the inside. This is being sold as-is."
