[SPARCbook] external battery

> I looked into [replacing cells], but cannot figure out how to open the casing,

1. there is a CPU inside the battery pack.
2. the external and internal battery contacts are mechanically 
   and electrically identical.
3. doesn't Tadpole sell an external case into which you must put your own NiCd 
   cells?  this thing would be great for using the SparcBook past its EOL, 
   if you could find one of them.
