Composite cable?

Postby OldComputerGuy » Fri Aug 25, 2017 3:42 am

Were there ever any composite video cables made for the Jr?

No, a standard RCA cable works fine, so there would be no need. There was only an RF modulator and switch box made for the Jr.

I may be misunderstanding your question. If you mean separated composite, I don't know. There is a RCA recepticle on the back of the jr for composite video. I have hooked up my jr to my Commodore 1902A monitor using it and it worked. When I tried it with newer TVs, the picture would come and go like the TV was loosing sync. There is a thread here somewhere from when I tried it.

The object here is to connect to a Commodore 1702 monitor or any similar monitor that uses 1
or 2 rca jacks for video and one for audio. Basically the standard red, yellow, and white plugs that were common back then.

That should work fine. I believe the 1702 has the same composite in as the 1902a. One rca cable from the PCjr composite port to the video port on the 1702 and another from the audio and you should be all set. The 3 plug cable gave a better picture by separating chroma and luma, but isn't supported by the PCjr. Use the ports on the front of the 1702.

You can use any standard RCA male-to-male cable with both the PCjr video output and audio output. Standard cables.

You can also connect it to an LCD/plasma/OLED/etc. modern TV, although there is a small chance it won't display correctly due to timing issues. It works on my 55" Vizio TV from 2010, if that helps.
