Looking in the manual or on the web, there is usually a key sequence you can
hold down (there is for the 89 anyways...) that activates that boot loader
code.  Get the boot loader program started on the calc, and then you can
resend the from file from your computer?  (assuming you have a graph link,
if not, go buy one, they are $20)
