Thanks Mike... that confirms my suspicions. I'd also guess the Dallas time
chip has an internal battery for the clock. Those Dallas chips seem to run
forever. I'd wonder if anyone has opened one up to see if it is feasible to
replace the internal battery?
In the mid 1990's Sun SPARC workstations were all dying because the
batteries in these chips failed. When they did the ethernet stopped
working, and since a 5 year old UNIX system with no ethernet is
basically a door stop, they became give away items.
There was a site with a web page documenting these chips and how to
replace the battery. The top of them was potted with a brittle compound
and could easily be chipped away from the battery with a pair of
diagonal cutting pliers, a hammer, or any other number of similar and
more precision tools.
They are not fussy about batteries, having no source of lithium
batteries with tabs, I replaced several with 3 or 4 AA batteries in a
flat plastic holder. Others I just soldered wires to available lithium
batteries.
