I have a question that I've been unable to find the answer to. I have an old Seeburg SCD-1 jukebox and I mounted an Asus Zenpad Z8 to the front of it. It uses Bluetooth to stream music to the jukebox and works very well. Right now the charge cable is plugged in all the time. I'd like to split that connection and keep the charge cable plugged in and also plug in an external hard drive if possible. This hard drive would store all the music. Can this be done?
