That's the same NVRAM/clock chip with built-in lithium battery that was
used in several Sun Sparcstations. The Sun hardware FAQ has lots of
information on replacing them with the Dallas equivalent, and has
information (and pointers to other docs) about opening it up to get at the
battery if you want to try using an external battery.

That's the same EPROM used by Sparcstations as the boot ROM.
