I have a DTC5160X RLL drive controller that has stopped functioning, potentially due to receiving bad power. I'm hoping that perhaps only the 27C64 EPROM has been fried. I'd like to replace it with a 28C64 EEPROM, but I don't have an image of the firmware. Does anybody here have such a firmware image? It did have firmware revision CRD19A on it, but I'm gathering that there are a few valid images that could possibly work.

Any help that someone could provide would be greatly appreciated!
