those are magnetic strips storing programs. you would read the strip in,
then insert it in a special holder below the row of function keys on the
calculator. you could label the strip so you remember what each function
key is programmed for. HP first introduced this with the HP67 (pocket
version) and HP97 (desk version) and TI followed suit with their own
equivalent. This was probably vintage late 70's or early 80's?
