James - REX doesn't take SD cards. Flash is permanently soldered to the board.
Are you talking about NADSBox? I think that's the only device for our machines that takes SD cards, but maybe I'm forgetting something. -- John. PS - reminder: please don't use swear words on the list... not everyone cares about swearing one way or the other, but those bothered by it *really* care, so why not accomodate them.
