TV/Game Switch” but it doesn work. How come?
A “TV/Game” switch is, usually, intended to switch RF (radio frequency) signals. For example, in the “TV” position it connects the TV’s VHF antenna input to the VHF antenna (e.g. the long “rabbit ears”). This way, you can watch TV. In the “Game” position it connects the TV’s VHF antenna input to a game machine’s or computer’s CH 3 or CH 4 output. To see the computer’s display, you need to set the TV Channel selector to the channel being output by the computer. The reason your setup does not work is that the IIe does not output an RF signal. (In fact, no Apple II has built-in circuitry for outputting an RF signal.) The IIe outputs composite video. Composite video is pure video information like the kind output by a VCR through the standard ‘Yellow’ cable. It produces a better, sharper image than video which is converted to RF and fed into a TV’s antenna input. The usual way to connect an Apple II to a display is described in Q&A 018.
