Sorry I haven't heard of this card before. If is a read only card then it will be EPROM. But if you can write to it then it'll need a battery. If it's not working at all then I'm guessing they are battery backed patches because an EPROM based card should still be reading OK.


I guess the thing to do would be open it and see if there is a battery inside and then try to identify it.
