compatible ones?
differences between my deck #1 and the others. I can’t conclusively say these are 100% reliable indicators, but they are conspicuously different. * The labels on the undersides of decks 2-5 have a box drawn around the serial number. Deck #1 has no box drawn. * The serial number itself on deck #1 is different from the others. The “72R4BR” prefix is very much smaller than the rest of the number. “AT85037836” is one continuous string of black characters with no spaces, while on deck #2 (#3-5 are similar), “A1 76 5904610” does have the spaces, and the “76” is stamped in blue. * The cart contacts of deck #1 have a definite copper color, while the contacts of the others have a silvery appearance.
