One of the first things to address was the trackball. The original ball was worn and dull so I bought a new ball also the rollers and bearings were all replaced to give the trackball a nice smooth roll.

Here in my hand you can see a comparison to the old worn rollers in comparison to the new installed smooth rollers:
Although the game was functioning I decided to do a little preventative maintenance & recap the ARII which regulates the power and audio. I ordered the kit from Bob Roberts website along with a few other items that I needed. The caps are all axial capacitors which have leads from both ends. It's also advisable at this point to resolder the existing molex connectors on the ARII.

I was seeing a drop in voltage from the ARII to the main board, I looked at my wire harness and edge connector I don't think it was making a good connection so I decided to pull each pin as tedious as that sounds and hand sand each one to make a better contact. Sure enough after sanding all of the pins I was getting the proper voltage that I needed. It's probably advisable to recrimp with all new pins but that method seemed to work for me.
This is one of the few games that I can think of that the speakers are built right into the marquee. I pulled off various parts and cleaned, sanded, painted etc..
Once I fired up the game I was unfortunately greeted to what looked like the blue screen of death in windows. I tossed the game into test mode and it said I had a bad rom with it's respective location.
Taking a break from the restoration for a moment ... Atari's Missile Command was found also seen in the TV show Chuck, along with one of my favorite movies Terminator 2: Judgement Day. On an episode of Chuck which is titled "Chuck Versus Tom Sawyer", Chuck needs to play Missile Command in order to avoid a real nuclear disaster apparently to the Rush song Tom Sawyer.

Game came out great and is a blast to play. I'm terrible at this game but it's really fun. Below is a picture of the finished game.
