This item is about 25 years old. The karaoke cartridges are "Detective Conan" and "Morning Musume," two in total. The main unit requires 4 AA batteries. This was a popular karaoke machine at the time. The power turns on. The image is analog. I have forgotten how to use it and do not know. The instruction manual is only for the microphone type. There is no original box. This is a long-term home storage item and may have some damage. If there are any issues, please repair it yourself. Please consider it for your collection.
