First off HELLO to all.  I'm new to group and am wondering if anyone 
out there has replaced there battery themselves and would be willing 
to pass on some instructions, tips, etc.... I bought this keyboard 
used around '96 and used it briefly as an emergency replacement for 
a midi controler that died on the road.  It served me well but put 
it away after I was able to get home and update my rig.  I recently 
pulled it out of the closet and started playing with it and 
instantly fell in love with its old school quality's.  It still 
holds the patches I've programed but I don't want to press my luck. 
The battery has to be easily over ten years old it appears to be the 
original.  Any Info would be greatly apreciated.

Peace
