Which MK5017 IC, exactly, does the SB-634 need? The MK5017 is actually
several different clock chips which have different suffixes that are
significant, determined by the specific function set of the chip. For
example, MK5017AA has an alarm tone output, MK5017AN has clock radio functions
(alarm and sleep timer switched outputs), MK5017BA has a calendar, etc. There
may also be a "P" somewhere in the suffix if it's a ceramic-packaged chip. I
believe I have an untested MK5017BA somewhere, if I can find it.
