An excellent document to assist in the repair of my old personal tape player. It includes full circuit diagrams and physical layout drawings and full instructions on disassembly and fault finding.
Well worth the meagre price.

Power On/Off Circuit When the power switch is turned on, a low level differential pulse is provided to terminal MI of the CPU. Upon receipt of the pulse, the CPU starts the power ON sequence and raises the APO signal to +5 V. When the switch is off, on receiving the KO11 signal at terminal KI0, the CPU drops the APO signal to ground level to shut down power.
