C4 wasn't generally available in Wales until the launch of Sky Digital and DTT (OnDigiital) in 1998. It was a major gripe for English-speaking Welsh viewers as S4C only showed a selection of C4 programmes in off-peak hours. It was only after the launch of digital TV that S4C became a full-time Welsh language channel. So in Cardiff in 83 it would have been BBC1, BBC2, HTV and S4C.
