I would think the firmware is the same on the other two cablecards, don't feel like rooting around in the TiVo menus at the moment. For sure they're model PK800 cards, I remember them all being green.
PK802 cards are two-way capable, have a predominately white label, and would likely never be issued separately from a Scientific Atlanta cable box.
