CI-700 Drive

I am repairing several bad CI-700 drive contollers. The hardware is all functioning and the only problem is the flash memory in the AT89c52 micro-controller is corrupt. I tried to read out a good AT89c52 but the flash memory area is locked. Does anyone know where I can find a copy of the HEX file. I sent an e-mail to Celestron eventhough I know they no longer support the CI-700, and have heard nothing, "go figure".

Is the CI-700 Celestron's Losmandy based drive? If so, I wonder if Losmandy could be of any help?

Does anyone know if the drive was manufactured by an outside source like Tangent Instruments for Celestron?

I hope someone can help me out.
