Can anyone write an address generation utility for an HP 50g graphing calculator?
The problem with your request is that it would be very difficult to copy the private key and address onto something more stable as well as something that could sign a TX. Your biggest problem is that once the battery dies on your calculator (or if you or someone else takes the batteries out) then you will lose your private keys along with your money unless you have backed them up
This may help a little:
