Arcade Games Asteroids mini



Do you enjoy Atari’s old vector arcade games, with the unique glow of a real vector monitor? Maybe even appreciate the discrete vector drawing engine implemented on a baking-tray sized circuit board? But don’t want to install an arcade cabinet the size of a refrigerator in your living room?

I built a half-size Asteroids cabinet, using a vintage game circuit board and a real vector monitor – a small one from a broken Vectrex, a home gaming console that came out just a few years after Asteroids hit the arcades. It took an additional homebrew circuit board to drive the Vectrex monitor fast enough for the Asteroids drawing speed.

The back shows off the Asteroids circuit board, behind a Perspex pane. Note the integrated carrying handle on top: Try that with a full-size cabinet!

As you can see from the images, I did not aim for an exact replica of Atari’s cabinet shape. Rather, my goal was to build a cabinet that is comfortably playable when placed on a table or a shelf – and, of course, which has room for the vintage components and the infrastructure they need. The Asteroids circuit board determines the cabinet height, which is a bit taller than a typical bartop cab.

This small web site shows some pictures of my cabinet, explains some of the non-obvious aspects of putting it together, and provides details on the homebrew XY deflection board for the monitor. Please use the menu on the left to get around.

Here’s what you need to build something like this:

No good Vectrex was harmed in the making of this game. ;-) I found a broken Vectrex, with missing controller and non-working game PCB – just the XY display turned out to be working. Perfect for this project!

Did I mention that this project was featured on Hackaday, back when I had just built it? :-)

Safety Notice


You will be working with mains power when building this, and with even higher voltages (up to 6 kV) when dealing with the CRT display. This implies risks of fire and electric shock. Be sure to keep yourself safe during the build process, and to build a system that is safe to use! I will not provide any specific safety instructions here – if you are not confident that you have the adequate technical background, please seek assistance from somebody with the required expertise!
