I wonder, why was the decision made to solder that battery in there in the
first place?  Was it because the NiCad was supposed to last virtually forever
(or at least as long as the machine)?  Of course, I replaced mine last night
else I wouldn't be asking. :-) :-)  My old battery seemed to have broken
itself in half.  Took me about 40 minutes, don't know if that'd be considered
good time or not...

Anyway, experience suggests that the only time you'd notice a dead (or
missing) battery is when the power is interrupted.  The system clock should
be normal otherwise, even through warm boots.

I didn't catch Mr. Reuther's original post, but if the clock on the A2000
doesn't seem to be keeping the most accurate time have a look at jumper
J300.  The jumper should be normally installed on pins 1 & 2.  Mine wasn't,
discovered when adjusting the A2320, and when the jumper was moved the
clock's accuracy improved noticeably.  This was also the trip `in' that I
noticed the severed battery...
