and 3) the video cable exhibits lower capacitance between the center lead and
the shield.
You can connect your Apple II to a Monochrome or Color composite video
monitor.

018- What is the usual way to connect an Apple II to a
display?
For a IIgs, you connect to the IIgs RGB monitor. For other Apple II's, you
use a video quality 'RCA cable' to connect to a composite color monitor, such as
one of the Apple II monitors or a third party monitor like the Amdek Color-1.
(The IIgs has a composite color output which can go to a composite monitor; but,
for IIgs super-res, the results are unsatisfactory.)
An alternative to a composite monitor is to connect to a color TV directly
or through a VCR. Most VCRs and many modern televisions have a composite video
input port. Rather than buying a new monitor, a person can usually use an RCA
cable to connect the Apple to a spare VCR or television. The stabilization
logic built into even a cheap VCR can go a long way toward cleaning up an ugly
picture.

019- Does anybody know how to do the "Color Killer Mod"
on a //e?
It looks like you should be able to do a full-screen color-killer on a IIe
by using a general purpose NPN transistor (2N3904, 2N2222, etc.) to shunt the
Color Burst signal. The transistor's collector would connect to the junction of
R15 and R13; the emitter lead would go to Ground. The transistor should be
connected directly to the R15-R13 junction and ground.
The base lead would go through a 2k-3k Ohm resistor to an annunciator
output, such as An-3 at pin 12 on the 16-pin J-15 Game connector. PEEKing the
appropriate addresses should flip Color OFF and ON.
The reason for qualifiers such as "looks like", etc. is that I have not
actually tried a mod like this on a IIe. Monitors are remarkably sensitive to
Color Burst. If the transistor does not do a good job of shunting the signal,
enough may get through to trigger Color-ON.
A more positve (but less easy) technique is to use a 74LS32 OR gate to
control flow of the 3.58MHz signal. The IC could be tack-soldered onto U88 via
its +5 and GND pins. U88 is the 74S02 which has the gate which produces Color
Burst.
