ISTR somebody recently mentioned soldering battery

of a Dallas CMOS clock chip. Does that ring any bells?
The method for installing a battery on a Sun NVRAM module is well
established and can be searched. I've done that one on numerous
occasions. I think the Dallas chips are laid out entirely
differently. Probably someone should dissect one with a dremel
tool and write a howto somewhere. It is a worthwhile project.
The upper module is almost certainly sealed seperate from the
chip itself, if it's like the Sun-type modules, there are
contacts somewhere you can dremel in to and solder on an external
battery lead.
I have a pile of 'old' Pentium II and Pentium III motherboards in
a box just waiting for me to desolder and save the Lithium
battery sockets from. I plan to epoxy them on any further Sun
NVRAM modules I 'upgrade' (and there are quite a few here that
still need that)
