|Road Runner - but in black and white|
This may have been down to the rather 'clunky' composite mod that I installed. This consisted of several resistors and a capacitor, somewhat clumsily soldered to the board in various places. I was, frankly, amazed that I got anything output that a TV could understand.
|Man, that is ugly.|
To get around the somewhat amateur nature of my mod I ordered a deluxe composite mod kit from the rather nice chaps at The Future Was 8-Bit. This has a rather nice discrete circuit board that contains a simple circuit to split out the composite and audio signals. This deluxe version has a simple connector with four flying leads and a 3.5mm four pole jack that accepts a composite/audio cable to simplify connecting to a TV even more. Nice.
|Lovely composite mod kit.|
|Sorry chaps - you're no longer required.|
All that's required is a few components to be removed as per the full colour instruction leaflet and then the four cables installed in the indicated locations. Easy.
|Nearly ready to go..|
And that killed the console. Dead.
If you turn on a working Atari Jr with no cartridge then you get a grey square with no sound in the middle of the screen. Well, it turns out that this is also what my Atari Jr decided it would do from that point on too, even with a cartridge installed. Dangnabit.
|It's dead (again) Jim.|
Either way, it's dead.
Back to eBay where I managed to find another Atari Jr for less than the cost of one of the TIA chips. Go figure. But it was a typical 'unit only, untested, worked when I put it away' but for the price it was worth a gamble. After a few days it arrived and, as luck would have it, it had the exact same revision of board... more or less. I won't dwell too much on this bit as I basically just took the board, cleaned it up and then applied the composite mod to it, and stuck it in my cleaned case.
|Unit number 2 - note missing silver label|
|Difference 1 - small cap now has its |
own place on the board
|Difference 2 - small cap is in different|
|Difference 3 - voltage regulator looks|
like a 1A rather than 0.5A
I did briefly toy with the idea of de-soldering the chips to put in my original board but I was too concerned that, if they are fragile, I might destroy them and be back to square one.
So I temporarily attached the composite mod to the new board. And....
|Let's try that again, shall we?|
|Colours, so many colours...|
Success! So, all that's needed now is to carefully solder the mod in properly and put it all back together.

Wires trimmed, soldered into place
and secured with hot glue (I'm not proud!)
|The connector board gets heatshrunk (shrinked?)|
|Cable connected up|

|MEEP! MEEP! This time in colour. :)|
