Dear all,
My 2200 was stuck in a POST reboot loop. It would check, RAM, ROM RTC then say waiting for signal processor the reboots again. During troubleshooting I replaced both Zero Power NVRAM and RTC chips. I only had old ones, but they must have enough juice left and this has appeared to have cured the problem. The 2 Parts in question are: MK48T128 zero power RTC MK48Z02 zero power NVRAM At some stage someone has replaced the original zero power NVRAM and RTC with the Dallas Semi equivalents which were really pricey. I found the new original part numbers to be much cheaper. I have also ordered both new ones for the princely sum of $20 AUD including shipping :) Well, I am hoping they are actually new and not flat... -marki _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
