A friend's mother has an RCA radio with a Television jack. Apparently
it was "television ready" in that you could plug your speakerless,
audio-amplifier-free RCA television into it.

The problem with both the RCA plug and the Motorola plug, compared to
other coaxial plugs, is that the hot lead makes contact before the
ground does.
