I purchased a famicom system along with about 4 cartridges including one that contains 190 different game along with a family computer disk system. The cartridge system works great but unfortunately the deal came with only one power supply and apparently two are needed to use the disk system . There are about 21 different disks which I can't test because of the lack of power. Does anybody know what type of power supply I need for the disk system and whether the power supply to the nes should be sufficient. I have tried the nes power supply which did nothing. If the nes power supply is sufficient does anybody out there have any ideas what I can do to get the disk thing working. Thanks
