I think I found a problem with that: The way the link port works is
actually not that simple. I am no expert, but I think it works on two wires
which are bidirectional. I don't think you can just "play" it back into the
calc.
What about when it says WARNING, MEMORY BACKUP??? It is waiting for you to
press continue which then sends a signal back to the sending calculator
which starts the transfer.
I don't even know if the link port will accept _sound_ being sent back into
it. Would the program convert those beeps and blips to the correct
electronic pattern? I am not so sure.
