Some use a CR-2032, which is a large watch battery about 3/4" in diameter
parallel to the motherboard, as Derek said.  Some of the very old
motherboards used several button batteries soldered together and
heat-shrink-tube wrapped with pins coming down to be soldered into the
motherboard.  It looks like a brown or blue keg about 1/2" long.

I did a search on that computer, and all I could find is places selling
memory for it, as it seems to take proprietary memory.
