A friend of mine recently bought a TI-89 with ROM 1.05, but of course he
wanted 1.00 for all the games.  So I tried to downgrade his ROM from my
calc with the "Send/Recieve Product Code."  Should that work?  It didn't.
 I tried sending to/from many 89s but the sending calc got a checksum
error each time and the reciever always locked up.  Any ideas?

Thanks,
Noah
