Atari 2600jr Composite Mod

 

To follow up on the 2600 mod,  but this time using my own pre-built composite video adaptor available here.

Right’o, lets get this jr open 😀

   

Humm.. Scabby!

Tin hat already removed. Now to remove the stuff we no longer need. (PAL)

Q4, L8 R56 and the RF unit removed. (PAL)

  

A picture says a thousand words. Use a sticky pad or cable tie to secure the PCB. (PAL)

Same kinda deal for the NTSC, just things have moved a little. Remove Q4, L6, R56, C33 and R17

And here are the connections for the NTSC version (don’t forget to remove the bits and bobs from the previous picture) NOTE Red arrow connection is the middle pin of the removed transistor (Q4) The pad to the right.

Use the corner of the case as the video cable strain relief.

The ribbon cable should fit nicely under the tin hat when you reinstall it.

This mod is available with or without cables. Bare PCB is ideal if you want to mount chassis terminals.

You’ll find before and after images on the 2600 and 7800 pages
