Black Widow

Play Black Widow on a Space Duel Machine:

Gravitar was not a huge money maker back in 1982 because, frankly, the game is difficult to play. The majority of people wanted to play games that were simple and easy. While the Gravitar controls were simple, the gameplay was anything but. As a result, many Gravitar machines were quickly pulled out of the arcades or converted to Black Widow.

Converting a Gravitar to a full Black Widow requires a Black Widow game board, a marquee, sideart, a new control panel, and a new wiring harness. The Black Widow harness is just like the Gravitar harness except that a few wires were added to support the control panel. In fact, it's fairly straight forward to modify the Gravitar harness to support Black Widow.

You can play Black Widow on a Space Duel machine with very little effort. All you have to do is swap the game board and the control panel and then plug in a simple control panel wiring adapter and you are good to go.

Assuming that you already have a Space Duel machine and a working Black Widow board and a complete Black Widow control panel, all you need now is the wiring adapter. Download the following pdf file to see how you can make your own wiring adapter. The pdf file contains a complete parts list with sources, assembly instructions, and lots of pictures. Before long, you will be playing Black Widow and if you do not want to give up your Space Duel, that's okay because you can always swap the boards and control panels back and unplug the wiring adapter in just a few minutes.
