Thanks for your time!

 GE> Is it black, rectangular, with one corner cut off?

Yes!

I just tried that with Seamonkey 1.0.3+ for OS/2 here.  White blank page
and that is all....

 GE> MFG Part#: B-282

OK .

 GE> Description:
 GE>  Lithium CMOS battery
 GE>  Clock and battery module.

 GE> Qty Availability: Backorder

Scowl, but ..

FWIW, the markings on this component are:

     SMARTBATTERY

     DALLAS
       DS1260100
       9112

     3 Volt Litium

It has a whole bunch of connectors in two rows in it, opposite the screw
hole and holdown screw and nut.  From the bottom of the circuit board,it
looks like there are only three of those solder pins actually used. But we
both know that there are more than one layer of a motherboard cat to skin
when thinking about such.  I can't see the top side of the solder holes
between the component and the top of the motherboard.  Even though there
may be no traces visible on top the board, it might be that there are
internal layers in use for the other pins.  Although usually when that is
done you see shim trim contact at the solder points that carries the
operation into the internal layers if my memory is right. There is none of
that visible here.

Thus, even though as another poster here suggested, I could pry the top off
it and there is a flat lithium cell inside it, in this case I can't. The
whole component is completely hard molded as far as I can see. There is no
seam line to get the top off.  That in contrast with later lithium cell
holders which do have a pry off top you can yank and change batteries
inside with.  I've done that on many other boards.

I've a couple other hits on Google for this thing and one 1-800 number in
the USA to call.  I'm acting on that now.  If you have any other
suggestions I'd sure like to know.  Like maybe milling off that top layer? 
Or is it completely potted into that black plastic block and you could not
do that?

Thanks for any thoughts anyone could give me here.
