CONNECTING THE 80-COLUMN ANALOG RGB DISPLAY
TO AN AMIGA
If you have a computer which displays its output in analog RGB, like
the Amiga, use the 23-pin RGB cable. You'll also need an audio
cable (a thin cable with identical phono jacks on either end) and a
"Y" adapter cord (which you'll need to buy).
1. Plug the larger 23-pin end of the cable into the port on the back of
the Amiga marked RGB. Manually tighten the thumb screws on
either side of the connector.
