From a collection. A well-known SHARP classic: SHARP JC-M50-BK. It seems to power on with batteries, but I haven't been able to confirm proper function due to the lack of cassette tapes. The battery contacts may be poor, as it sometimes works and sometimes doesn't. I think it would benefit from internal cleaning. 　 As this is a very old item, I cannot guarantee its operation after purchase. It is being sold as a "junk item." If you have any concerns about purchasing, please refrain from doing so. I only wish to sell to those who can properly maintain it, will cherish it, and understand its condition.
