Not for the squeamish

Here are some photos of the "real" Artie's surgery:

 

The new CD4050 was taken from a donor. In this case, an unused video mod:

The old chip didn't say CD4050 anywhere on it. But Albert pointed out that this is indeed the same as a CD4050:

If you do any of this kind of stuff, the best $11 you'll ever spend (and one of the few useful things Radio Shack still sells) is on a desoldering iron. It makes removing old components like this much, much easier:

After desoldering, the new socket was installed:

And the donor chip popped into place:

Hopefully, this will be the last time I'll have to open up my 2600 for awhile. I've actually stripped out a couple of screws, since I've had it apart so many times (due to testing video mods). Before I test any other video mods, I plan on getting another six-switch just for that purpose, so I can leave this one for actually playing games.

The Radio Shack desoldering iron can be nice, but it might not be a bad idea to periodically check to ensure there's no continuity between the metal exterior and the AC line. One of my coworkers where I used to work was using one of those things that developed an internal short to the frame. Blew some traces off the board he was trying to repair.
