I have auctions not far off closing for an Atari 800/XL/XE Monitor Port to
SCART cable and an Atari 800/XL/XE Monitor Port to RCA Phono cable. These
are suitable for PAL or NTSC systems (but NOT SECAM). They are useful if
your TV output has become noisy. These cables use unmodulated composite
signals to carry the picture and sound to the TV and give a far superior
image to the RF (TV) cable.
I also have some very cheap TOSlink (optical) cables available, along with
some DVD setup/calibration discs.
