Composite mod for the Atari 2600 Jr PAL Rev. F

[Dionoid]

I've read several posts about people saying that no composite mod exists for the Atari 2600 Jr PAL Revision F.
However, you just need to know which components you have to remove and how to connect a specific composite mod, which I'm showing in this post.

 

For my mod, I've used the Deluxe Composite Video Mod Kit sold by thefuturewas8bit.com (and designed by Tynemouth Software).

I like this mod, because it includes a 3.5mm jack socket which perfectly fits the Atari Jr, without the need to drill any holes in the console shell.

Also, this mod gives me a crystal-clear composite output.

 

Instructions

[warning: these instructions are only applicable to the Atari 2600 Jr PAL Rev. F.  For other revisions, please read the online instructions on thefuturewas8bit.com]

 

After opening you Atari 2600 Jr PAL Rev F, you should remove the original RF plug, and then remove components Q4, L6, R17, C33, R48 and R56 (see below).

 

 

Then solder the 4 wires of the composite mod (yellow, red, black and white) to these positions:

 

 

Note that I actually soldered the wires to the back of the board, by pulling the 4 wires of the composite mod through the little hole left by removing L6.

IMO that looks better.

 

 

Then I placed the 3.5mm jack socket where the RF connector used to be, using the included double-sided tape to raise it a bit, and a small tie-wrap to keep the socket in place (note that the tie-wrap goes through the holes that were left by removing the RF connector)

 

 

Then I mounted the inner shield back on:

 

 

And finally used a black marker to color the double-sided tape black. 

 

 

Hope this helps!

Note that for Atari 2600 Jr PAL Rev. F (similar to most '2600 Jr NTSC consoles), the modulator components are integrated on the board.

So that's the reason for removing R17, which will basically stop interference from the modulator by disabling it.

Just this minute, I’ve cracked open an old junior to discover it was a revision F. This is gold dust! Thanks
