Thank you for viewing. This is a top-of-the-line Betamax model from the late 1980s. Power has been confirmed, and the play, fast forward, and rewind buttons are also working correctly. The LCD cover on the front is cracked, so it is protected with cellophane tape (see photo). I don't know much about this machine, so I can't perform specific tests, and I cannot guarantee whether the specific operations will be normal after you receive the item. Since the operation has not been fully confirmed, it will be treated as junk. The items for sale are the main unit only. Please purchase only if you understand this.
