Colortrak - Design Quirks

Design Quirks

During the early 1980s, RCA responded to increased demand for component televisions with monitor capabilities by adding composite and S-video inputs to the Colortrak lineup. These inputs allowed owners to easily connect a stereo audio/video source, like a Video Cassette Recorder, LaserDisc player, or with use of an RCA SelectaVision CED videodisc players to the television. For example, early composite video-equipped RCA sets were to coincidentally be tuned to Non-broadcast channel 91 to display a composite video signal, if a set was equipped with more than one input, subsequent inputs are designated to channels 92 to 95, which are usually accessed from the remote control. However, when manufactures learned that accessing input mode within numeric channels pressing channel up/down was feasible, channel 9x channels were dropped from future models.
