Be A Maker! - APB Restoration Part 2

So after replacing all of the capacitors and the horizontal width coil on the monitor chassis AND not killing myself from the high voltage, I'm getting closer as seen in the before and after photo above as the picture is almost filling in the entire screen.

One possible issue could be this width coil as it doesn't look fully right.

However, finding a part like this is next to impossible since these parts are 30+ years old.

Be A Maker! - APB Restoration

As you all know, I'm a child of the 80's so I've always had classic arcade games in the brain. So for my first restoration, I'm going to be looking to fix up this classic Atari All Points Bulletin. I'm excited to expand my knowledge of electronics especially in the realm of CRT monitor repair.


Though it plays fine, there's a few technical issues that I need to address. The first is that when the player presses the siren, the marquee should be flashing like the police car roof lights. A previous owner for some reason took out the light fixtures and replaced it with a bar type fluorescent light. And the second is that the monitor doesn't fill the entire screen and the horizontal width coil is busted. I'm looking forward to playing with the 20,000 volts that these monitors put out.


DB Engineering Is Stretching Its Legs!

The DB Engineering Program is moving to the much larger Room 201. Students will now have a lot more space to do their projects and access their materials. As you can tell from the photo its going to be a work in progress but its going to be well worth it in the end when we get settled.
