Casio magnetic data cards for the Pro fx-1

Thanks for the reply.
So on this page:
http://casio.ledudu.com/pockets.asp?lg=eng&type=264

it says at the bottom of the instructions to press AC and MAC before writing a program. Now, it uses 'write' to mean type in a program, rather than record on a card, so does it mean press those keys in WRITE mode or RECORD? If you press them in WRITE mode then the AC clears the program memory and the MAC gets recorded as a keystroke. If it means before you write a card then it is being inconsistent in naming RECORD as write.

Do you use the keystrokes you listed to successfully write a program to a card?
I'm pretty sure I have done those keystrokes and I don't get a successful read. No error LEDs light up, though, which has me confused.
