## Scope Notes

- The public trail is strongest for manuals and related CCU documentation.
- Exact forum repair discussions for RM-M7G and RCP-TX7 appear sparse.
- The control connector is repeatedly described as a 10-pin remote interface
  using an RS-232C-style/proprietary Sony protocol. The electrical pinout and
  higher-level command protocol should be verified from service manuals before
  connecting custom hardware.
