I once had to repair a Genicom printer that had blown a chunk out of a processor chip. On investigation it turned out to be a little more than just a processor as it was also programmed with the firmware.
I first looked for a copy of the firmware in the extensive archives we had at the time and found nothing. With a second glance I decided it was worth having a go at reading it with the programmer and the file copied without any errors. I ordered a new blank chip from Farnell and loaded the data into it and it worked even though the processor had blown up in the same package right next to the firmware ROM in the old one.
