I've downloaded the flash memory contents from a BC637PCI card, it's a 128K file but also had to save it as 64K to please the disassemblers I found online. That didn't look to be an issue, as far as I can tell only 64K is used anyway. The memory chip is a CAT28F010, as opposed to a 29F010 shown in the schematics, and the processor is an MC68HC11F1CFN4. If anyone wants to talk a look my files are here.... https://www.mediafire.com/?kavvrm2cow2365c There's the two binary files there plus some of my efforts at disassembly but I have to admit the disassembled files do even less for me than the binaries:-) Other than some messages at the beginning of the data area that seem to relate to file update processes, perhaps for the GPS and oscillator options, the only other obvious text string I found just said BC635IRIG. I know that may not be too significant in itself but there's 512 bytes of EEPROM inside the CPU and I'm wondering if that's handling the personalised data such as serial number and configuration etc. None of which helps with the 1024 week offset of course:-) Regards Nigel GM8PZR _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
