    Stefan, WHICH version is the one needed by the 65SX?

    You must... choose wisely...

    Idk, I have both nwx but no 65SX. I could try my 55SX, however. (Also has a DS1287)

    If the linked Dallas DS1287 datasheet on the 65SX page is correct, the variant with BQ3285 should be the right one.
    Question is, which version Carsten tried.


    I just had a look under the hood, and the chip is: BENCHMARQ BQ3285LCS
