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.
