This is the Family Computer Disk System (HVC-0220) and the HVC-023 RAM Adapter, peripherals for the Family Computer, released by Nintendo on February 21, 1986 (Showa 61). The power cord is not included. It has been stored at home for a long time. I do not recall ever using batteries with it. Since I do not have the original Famicom, I cannot confirm that it works, so I am selling it as junk. Please understand that there is no guarantee of operation. <Accessories> ・Main Unit ・RAM Adapter Nintendo / Nintendo / Nintendo
