A great copy of the manual, and the only one I could find anywhere on the net! The circuit diagrams are easily readable, all component values marked and easy to see. A highly appreciated download!

1.4 POWER SUPPLY AND LOADING SECTION
The power supply of the system uses VD (8.3V) from the mother board. VD is fed to 5 channel CD driver IC, 5V Reg IC and disc detection LED. The microcomputer turns on or off the CD driver and the 5V using �CONT� and �CD5VON�, respectively. The loading drive is turned on or off by the input signals �CDEJET� and �CDLOAD�. No control terminal is provided for turning the loading drive on or off.
