Pin 12 of the 'S02 would be bent up and connected to the output of an 'LS32
OR gate (e.g. pin 3). One of the OR gate's inputs (pin 2) would go to Pin 12 of
the 'S02 socket. The other (pin 1) would go to an annunciator output.
Turning ON the annunciator forces the OR gate output to "1" and eliminates
Color Burst. Turning OFF the annunciator lets the OR gate output follow the
3.58MHz signal and enables Color Burst.

020- I connected my IIe to a color TV using a Radio
Shack"TV/Game Switch" but it doesn't 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.
Getting an "RF Converter" ("TV Converter", etc.) module is another way to
go. For about $30 Radio Shack sells a box which will convert an Apple II's video
signal to RF on CH3 or CH4.
One thing to consider when looking for ways to connect to a color TV
without a standard "Video" input is that you could end up wasting time and money
better spent on just getting a standard composite color monitor (like the Amdek
Color-1) at a local Apple II swap meet.

021- Can I use a color TV with my IIc+?
Yes. You can use one of the methods described above, or (for TV's with an
S-Video input) some module for converting to S-Video (e.g. Video Turtle); or,
you can use the RF Modulator module especially designed for the IIc series.
The IIc RF module is formed to fit the IIc case and has a "CH3-CH4" slide
tab on the top. Once the module is plugged in and a cable run to the TV's
antenna inputs or to a TV/Game switch, you can get very nice, colorful on-TV
hires and double-hires displays.
