How do I determine the ROM version of my HP-41x card reader (82104A)?

Do a CATALOG on the peripherals (fn CATALOG 2). The rom version is displayed in the name of the card reader catalog. The first version of the ROM just says "CARD READER". The later ones say things like "CRD RDR 1F" where 1F is the version number.
