Ming- There is a place for the "rec out" connector, just inside the hole covered by the little piece of plastic. Order a "cassette jack" for the Radio Shack Color Computer, from Radio Shack parts department. You may have other sources for this PCB mounted, 5 pin DIN connector, since it is fairly common. Before attempting to mount the connector, you may have to clean any excess solder out of the holes on the PCB. It's a tight fit, so be sure the connector is seated all the way. If you're successful, it will look like a factory job when you're through! Of the 5 pins, the center one is signal ground. Two pins on one side of center, are connected via resistors to ground. The two pins on the other side go to low level, left and right stereo signals. They are fed from voltage-dividing resistors, so short-circuiting them will not hurt anything. The signal level is just right for many tape recorder microphone inputs, and is not affected by the DX-440 volume control setting. fred-mckenzie@ksc.nasa.gov
