  For two reasons: 1) the battery on a P6 is located in a *very* bad place
in terms of battery leakage causing major malfunctions. 2) The battery in
the Korg gear of the early-80s all used NiCad cells, which leak.  Other
machines such as the DX7, etc. use lithium batteries, which do not leak.

  I'll be posting a Korg Trident MkII battery replacement procedure before
long--I snapped all the photos a while back, but haven't had time to make
the web pages.  Thankfully, the Trident's battery is in a much less
prone-to-damage area.

  FWIW, the Poly 61's NiCad is also located in a bad place w.r.t. leakage
causing big failures.
