Heavy Sixer and the fire button problem

[llioncourt]

Hi, everyone!

 

This is my first post and I'm already asking for help... Anyway...

I just got myself an Atari 2600, it's the so called heavy Sixer (I guess... I can't really tell, but since it's way heavier than my Darth Vader one, I guess this is it). to my demise it has that constant player 1 fire button problem.

 

I've read several posts here about it, and most of the time they said that the issue is with the 4050 buffer chip. I tried to look for some sites around here ( I live in Brazil) selling it, but not luck so far... But the is another solution "the bypass"!

 

I saw a picture of the schematics on a post, but since I can't really understand these things I wonder if someone can make a "for dummies" explanation for me... I really want to "save" my new-old beast.

I'd recommend replacement over the bypass for longevity. The 4switch models don't use the 4050 and have more TIA failures. TIA's are far more expensive to replace.

To bypass, you must cut pins 6-7, and 9-10 from the chip and solder them together.
