Paddle hookup & off color. Help needed.

Post by eatcrayons »

I've been reading this forum for a while gathering info, but I've run into 3 'problems'

First, the system I want to hack up is a spare that I have. It works fine with the exception that some color is off. The greens in games display blue and blue display red. All of the other colors are fine. I've fiddled with the color pot inside to no avail. If I hack this up with an A/V mod, should this correct the problem? Or more specific, is this color differation a problem in the RF saection of the board?

Second, I've been looking through the guides on this site and other places, but none of them show how to remove the little red tower on the section of the board with the chips. From the looks of things, it can just be cut off, but I was wondering if anything else is needed. How do I remove the red tower and keep the Atari working?

Lastly, a question. Port 1, the first paddle button goes to which pin on the chip that works the triggers? Player 1's trigger, correct?

Port 1, second paddle button goes to which pin? Would it be the first player since it's the first port, or player 2's pin since it's technically player 2's controller?

I'm guessing that paddle 1's button goes to player 1, paddle 2's button goes to player 2. This is based on the fact that each button has a different pinout on the controller port, and it wouldn't make sense to have seperate pinouts just for it to go back to the same pin on the chip.

I'd just like some further info on this before I go soldering stuff.

Thanks in advance.

I was wondering about that thing, too. Atari put it there for a reason, but what the heck is it and what does it do?!?!?! I just snipped mine off with a pair of wire snips. NBD. If you have a desolderer, it looks like you can get it that way, too.

1. I'm not sure, it may work, but I don't know what the problem could be if the knob does not work

2. the tower is called an inductor. If you are doing the A/V mod, you don't need it anymore, it's part of the RF circuit. Just desolder it and throw it away, or throw it at people... whichever you choose

3. each set of paddles has 2 that go to one plug. The first player has the same pin that is right on the joystick, the second player is left on the joystick. See abbibi.cogia.net or atariage.com for schematics.

I'll be honest with you - I would have never guessed that.

I've looked at those schematics for the paddles. Left controller's trigger goes to pin 4, right controller's trigger goes to pin 3. Since they go to different places, this leads me to think that they ultimately go to two differently places on the chip back on the board.

If I only have one controller port wired for paddles, pin #4 on the controller port goes to Player 1's trigger pin on the chip, and pin #3 goes to Player 2's trigger pin. Correct? Sorry if I wasn't clear in the first post.

Yeah, that sounds about right :D

Rather than make a new topic, I'll put this here.

I just got the 1mega-ohm pot from Radio Shack for the paddle. Only problem is that the rod the paddle knob attaches to is about 2 inches long. If I Dremel this part down to about 1 inch, would the pot still work?

as long as the metal on the wire connects to the metal on the pin, you're fine :D
