Demo disc promoting the features of the Sony Lasermax LDP-2000 industrial LaserDisc player, with emphasis on the interactive capabilities of the player. Packaged in a plain white jacket without artwork. The mint markings are rather unusual, having the lower case "a" in the batch number and the designation "DUMMY 003" on the "dead" side. However, they also include the long curved barcode which is normally seen on DADC Japan products.
