Power-on and character input confirmed! Not confirmed as I don't have a floppy disk. Only those who understand this, please. In the unlikely event of a malfunction (failure) that differs from the product description, we will respond with a refund after receiving the returned product or a refund within the Mercari site, so please contact us before giving a rating. If you rate first, the transaction will be considered complete under Mercari's terms and conditions, and we will not be able to respond. Thank you.
