Audio/Video Connector¶


Note: The connector used is a full size 8-pin 262° DIN, also known as the ‘horse-shoe’ type. A 270° DIN plug does NOT fit without violence.
The 8-pin DIN (audio/video) connector can output several different video signals, for each type you need a special assembled cable.
Output signals
- Composite (CVBS) (PAL)
- S-Video (PAL)
- RGB (PAL)
The Composite and S-Video cables are the same as you use for the original Commodore 64.
Pinout¶

Pin | Modulated Color | RGB Mode |
---|---|---|
1 | Luma (Y) | Green |
2 | Ground | Ground |
3 | Audio Out Left | Audio Out Left |
4 | Composite (Y+C) | Red |
5 | Audio Out Right | Audio Out Right |
6 | Chroma (C) | Blue |
7 | Not used | CSync |
8 | Not used | Fast Switching |
Audio¶
The audio outputs have consumer electronic line levels (Line Out) and need to be connected to an external amplifier.
Video¶
The video signals on pin 1, 4 and 6 have a source impedance of 75 Ohms, with standard 1V-peak video levels. In the modulated color mode, Luma and Composite contain sync information (-0.3V), while Chroma does not. The video blanking of the VIC output has been corrected, and is now in accordance with specification.
The PAL output is non-interlaced, with a field rate of 50.2 Hz, and line rate of 15.639 kHz.
The Fast Switching output is a 1.5V fixed ‘high’ output signal (when terminated with 75 Ohms), that is used on SCART to enable RGB mode. The CSYNC output is a sync-only output that is needed on the SCART signal as a replacement of the composite video or luma signal. In RGB mode, there is no sync information in either R, G or B; i.e. no ‘sync-on-green’.
