CI-700

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".

I hope someone can help me out.

John,
Please keep us posted when you find an answer. I am looking to buy a mount and the target is still G11 but if there is some nice CI700 it might work out. Too bad the manufacturer doesn’t support it. There are quite a number of out there. For the same reason I am reluctant to go towards CGE which costs almost 3 times of a CI700.

I am still looking for help and information with the CI-700 drive.

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

I hope someone can help me out.
