Pair of Data East Dot Matrix pinball display circuit boards in
untested condition. We found these boards in a recent warehouse cleanout. We have no idea if they work. They have been sitting for many years. One is labeled Data East Part #520-5042-00, the other is a Cherry branded board with a Data East sticker on it. This one appears to be missing an eprom.
Boards are sold as-is, see photos for more details on their condition.
