This is the battery that maintains the PRAM when the computer's off and
also runs the clock.  I bet the clock's reset to 1956, hasn't it?  The
PRAM holds settings like 32/24 bit address and so on.

The problems you're getting are classic symptoms of a dead battery and
can be solved by fitting a new one.  RS, Maplins, and firms like that
stock them as far as I know.
