Curiosity about HP-65 Standard Pac

[albertofenini]

Hello Everyone

sorting out things in our boxes, we have found a Standard Pac for HP-65 that includes a couple
of cards not described in the Standard Pac Manual.
Looking at the attached picture you will notice a STD 1A card, and a STD 14B.
Our Standard Pac manual starts describing STD 1B Day of the Week but it doesn't mention a STD 1A card,
nor it mentions a STD 14B which has the same title of the STD 14A but has different inputs.
Any hints ?
Thank for the great support !
