First, the Commodore 8-pin DIN connector is the unusual one; the "Hershman"
or something. This means that pins 7 and 8 are not in the same positions
as on the common 8-pin DIN connector. (Look at the port to confirm pin
placement; I'm not sure the chart below is correct.) One easy solution
here is to cut pins 7 and 8 off a common 8-pin connector; they aren't
needed for anything. Or as explained below, you can use a common 5-pin DIN
connector; but, if you're hooking to a separated color composite monitor,
your picture won't be QUITE as sharp.

Looking at the port on the back of the computer, OR at the BACK of the DIN
plug (the side you'll attach the wires to), the pinout is:

   8 7
3 6 1
   5 4
      2

Connections are:

1 Luminance
2 GRND
3 Audio
4 Color Composite
5 Audio In (not used)
6 Chroma
7 NC
8 NC

Hook up pin 3 for audio in all cases. As to video, if you're using a
separated color composite monitor, do separate RCA plugs for 1 and 6. If
you're using a color composite monitor with the single input, use 4. If
you have monochrome, use 1. If you want to use a 5-pin DIN connector with
a separated color composite monitor, do separate RCA plugs for pins 1 and
4.
