This was originally a Tapper cabinet. These were converted at the factory into Timber when Tapper didn't sell. Timber didn't sell either. Dunno why, it's a fun game.
I picked this one up from Stephen Beall in a bulk-trade of games. It's another one of the games his market doesn't tend to buy. The monitor was gone and the power supply did not work, but that was soon fixed. I put a switching supply in it and designed a little circuit to act like the original power supply's reset circuit (see my "random info" page for details). Works great now.
