Notes

- PCB got damaged by leaking batteries
    -> Cleaned
- Shell shows no sign of leaked batteries and the display cover still
  holds and seems to be original, although the display underneath was
  very dirty:
    -> Maybe shell was swapped at some point
- Link port cover was missing:
    -> Attached replica part
- The part that holds one of the screws in the battery compartment, just
  above the speaker, broke off:
    -> glued
- The part that holds one of the main board screws, near the battery
  spring, broke apart:
    -> glued
- All six tri-wing screws and one of the main board screws are corroded:
    -> replaced
- Sound volume is very low
