I bought a Casio fx602p and found a puzzle

Well, it might be a puzzle, or it might be a coded shopping list, or something completely ordinary. It's a puzzle to me though.

The numbers don't appear to all be primes, so I don't think the calculator was used with a program to find primes. The other card doesn't have all the letters of the alphabet on it, so can't be used to code words. At least it can't code all words.

Here's the cards in close-up:

What are they for?
