Current composite and S-Video cable options for compatible Commodore computers, with a five-pin composite branch that also serves selected Atari systems.

The two five-pin products exposed Add to cart controls, while the eight-pin product exposed current priced options on 2026-07-30. The five-pin cable and adapter carry composite video and two audio connectors; those connectors do not create an independent stereo source in a stock mono computer. The eight-pin S-Video branch requires a host that supplies separate luma and chroma. Its stereo option requires a compatible second audio source on the designated extra pin. Match the connector, resistor, audio wiring, display input, and regional video standard before ordering.

Host-specific C64 and C128 breakouts with open eight-pin designs plus an assembled five-pin option for early C64 boards.

Retro Rewind listed the assembled eight-pin C64 version, while Commodore4ever listed both eight-pin and early five-pin C64 versions on 2026-07-30. The open eight-pin C64 and dedicated C128 variants remain buildable from board, BOM, and case files. The standard C64 board physically blocks the IEC port on a C128, so use the dedicated C128 layout there. Optional two-channel output requires a second SID or similar source wired to pin 7; otherwise both output channels carry the computer's mono audio.
