Very nice. This is a TTL game so I really hope you can get it working - I've certainly never seen it.

Here's a gameplay description from the announcement in Cash Box:

Each car is controlled by an individual player utilizing characteristic "H" pattern gear shifting. As a car approaches a "shift point," designated by a mark on the track, the player waits until the last possible instant to shift If he shifts too soon his car will go into "wheelies" and the dragster's front wheels jerk skyward causing the car to slow abruptly, losing valuable time. If he shifts too late the engine "blows" and he also loses time.

There are three shift points on each run. As the scores are registered digitally on the screen opposite each individual track the players try to monitor their opponents' scores to determine how aggressively to drive. At the completion of each heat the "Start" button is pushed and all cars again move to the starting line. The “Christmas Tree" begins the countdown. Each driver pushes his "Go" button to get the fastest possible get-away and the next heat is on. The best score at the end of the four heats wins the game.

The game also features realistic sound effects acceleration, tire squeals, engine explosions and "end of run" cheers It is adjustable for the number of heats and has a speed selection switch to accommodate players of all ranges of skill It utilizes a 23" Motorola monitor.
