ERROR FIXEDThe connections are correct on the diagram however the numbering of the pins differs from the manual. According to appendix C of the C128 system guide the center pin is labelled as Pin6 (chroma).APPROVED
ERROR FIXED************************************************************************

Here is the A/V connector of the C64 and C128 shown facing the rear of
the computer. Note that early versions of the C64 have a 5 pin DIN
connector while later versions have an 8 pin. The two are wired exactly
the same, except that the 8 pin connector has a separated chroma (color)
output on pin 6. Earlier C64s didnt have separated chroma. Note the
U shape of the connector pins. Its different than the circular
pattern of the RGB DIN connector on the 1902A monitor, for example.
Note: the early two wire cable (5 pin DIN) is used for composite video
and audio only, and a three wire cable (8 pin DIN) is needed for Y/C
video and audio.

see note below -----8 7-----no connection
6---------chroma out
audio out -----3 1----- luminance (B W signal)

audio in -----5 4----- composite video out
2----- ground

Important note: the later C64C and the C128 both have a power supply
line going to one of the unused pins: pin 8. Be careful!!!
