Atari Asteroids for sale. Gameplay is perfect, it has all the sounds, all the buttons work perfectly, etc... New Big Blue capacitor. This cabinet was manufactured by Sonic, a distributor for arcade machines typically outside North America. The monitor glass is silk-screened as opposed to the...

First off, a big THANK YOU to the KLOVers who helped me get this killer machine up and running. Now that I am being challenged by this beast, I need some advice on how to WIN! I find at the higher levels (that would be the red ones for me...) all I can do is hold down the fire button and hope...

I was going through the resistors I installed in the K6100 to make sure I didn't put any in the wrong place and I noticed something that seems off. In the "additional parts kit" I ordered resistor R910 (according to the instructions that came with the kit) should be 6.8K ohms 1/4 watt. The...

Darn... I successfully installed the socket and the new chip but the measurements on the new chip are the same as the old one. I measured AC voltage on pins 7 (x) and 10 (x ground) on the big white connector that goes to the monitor. I'm getting 0.00 volts. Pins 8 (y) and 11 (y ground)...

I bought a new TL082 from Radio Shack to replace the (presumably) bad one at D11. What's the story behind installing a socket when replacing an IC? Is that to make future replacements easier or is it a necessity whenever one is replacing an IC? It appears the holes I would be desoldering...

Here are my results. It looks like the Y amp at D11 is bad, do you agree? If so, will simply replacing that TL082 and retesting be good enough or could there be more bad parts upstream that could burn out my freshly replaced TL082? By the way, thank you all for helping me along. I can't wait...

I made a mistake. When I was measuring voltages on the X and Y lugs I was measuring DC current instead of AC current. I measured AC current at the big white molex connector that goes from the game to the monitor. I made these measurements without the monitor being plugged in. Now I am...

I pushed down on each of those molex pins and they didn't have much give to them. I think the neck socket pins look fine but I will post a pic later because maybe a second set of eyes will catch something I am missing. Thanks for your help! :-)

Okay, I really want to try and do this but I might need some help. The chip at D7 doesn't look like a TL082. It's an Atari chip that says 136002 125. See pic here. http://yfrog.com/jq20100327180405j If this is okay, then great - I'll measure away. Just to make sure I am clear, I should be...

Okay, I measured the voltages at P900 and came up with 23, -25, and 182 volts on Pin 5. Do those first two sound within tolerance?

The neck socket looks okay, but the voltage measurements are a little off. The 3792 transistor measured -25.6 volts and the 3716 transistor measured 23.2 volts. I'm going to measure B+ at at pin 5 of P900 and will post the results...

Hello all, I recently picked up a Tempest cocktail with a monitor that had blown F100 and F101 fuses. I installed an LV2000, did the Bob Roberts cap kit and additional parts package and resoldered the connectors. I tried the monitor and the spot killer is lit. I cranked up the brightness...

My Ms. Pac was humming like mad and it turned out the problem was the florescent marquee light. As soon as I removed it the noise stopped!

Hi all! My Space Invaders is acting strangely. At first I was sure I had monitor issues but the more I fiddled with it the more I think the monitor is just fine. What happens is the game powers up just fine and I can start playing. After a few minutes though, the screen will start to act up...

Duly noted. I have a new GO7 flyback right here, I'll swap that in today. Thanks again!
