I started learning/working on my Qix back in 2001. The original boards along with several others I picked up along the way have spent most of the time in the closet. I worked on it again for about 3 months in 2005 and just pulled it back out a couple of weeks ago.

So, I finally got the power supply to work by replacing all the normal stuff (transistors and bridge rectifier). Tested all of the voltages and they were perfect but I still could not get any of the boards to go into self test. I had replaced all the ribbon cables with new and pin checked the entire boardset interconnects. Still no self test. So tonight I finally got the idea to spray some contact cleaner on the 40-pin posts and dried it. Hooked it all back up and nothing. Then I realized I needed to ground J19, pushed the button and about fell off my chair when the lights started blinking something that was actually in the manual. So, it goes through the tests, had a bad ram in U42. Reran the test and I think it finished.

So, my question is -- what is normal for the self test. They go so fast I couldn't catch all the testing. It stays on 00 0101 most of the time, then a couple of other flashes and then all out. The last few tests are very hard to see. Unfortunately, I have not fixed the G07 yet so I am blind to what is going on on the screen. For the Qix/Zookeeper experts - did I pass all the tests?

Thanks,
Daniel
 
After the test is finished can you close the coin door, coin it up and play blind? I think it is default to have attract sounds on so if you power up the game and it is running you'll know it. Mine wouldn't do anything but blue screen and would get hung up in the self test. It turned out to be a bad connection of 12volts at the video board. I believe it goes through the self test pretty fast then turn off when done. - Barry

Unfortunately, my cab is in storage right now so I can't check it that way yet. I guess I need to get the G07 working next.
