I'd forgotten about those little cables. If I recall correctly, they were small round cables, with maybe four conductors and a little flat connector with a clip?
4-conductor audio, generally.
Later on there was a generation of two-conductor cables that used SPDIF/PCM Audio instead of analog audio for better fidelity.
