Commodore VIC-20 Audio/Video

5 pin DIN 180° (DIN 41524) female at the computer.

Notice that the video output is on two pins. They are the same (wired together inside the computer) on some versions, and output a slightly different signal level in others. Use pin 4 for interfacing a video monitor such as the 1702 and pin 2 for the shield (ground).

Note: The prewired CBM cable should be the two wire type. A three wire cable used for Y/C video (C64 or C128) will not work.

Note: Be careful of the +6 volt line! It's there to source power to the -external- RF modulator used with the VIC20.
