My Asteroids cabinet was in very good condition. Including the original control panel overlay. Finding a working Asteroids can be very rare and this one wasn’t working either.
As with so many Atari games, first start checking the power supply and then the Audio/Regulator (AR for short) board. Also check the edge connections on the PCB board, they will get burnt if the voltage slips. So after I got the Asteroid to power up, it sounded like it was playing blind. Well of course that means monitor problems. After making adjustments, I was pretty excited to see moving asteroids. But there’s a problem, See the image:
There’s a bright DOT in the middle of the screen, DOTS in each asteroids and with retrace lines all over the place. The Problem was the Z AMP was out, then I did a full re-cap, replaced about a dozen small signal transistors in the def board and a little trace reworking. Hey after that, GOOD AS NEW!!!!
Every arcade machine or pinball machine I own needs to have a 3 prong plug. Meaning that they need to have the ground plug. I would say at least 25% or more of the game I’ve added to my collection has had bad plugs, the ground plug cut off or broken and a loose plug. So if the cord is still in good shape you can just replace the end 3 prong plug. Here’s a video I made of me changing one on my Asteroids machine. It took about ten minutes. With just a minor set back when the new replacement plug I bought was missing the screws!
You can not have a classic arcade with out Asteroids! (plus a Pac-Man and Donkey Kong) When I was ready to buy an Asteroids I couldn’t find one. So we called a few old operators that we found. One had an Asteroids that he had personally owned since buying it when it first came out. So it was a one owner machine. He had it in storage because it didn’t work any longer. It was in very good shape, including the control panel overlay. I got it at a great price and took it home.
Next, time to fix the Asteroids!
