NOTICE:

You can’t link more than four cabinets.

Networking Pointers

•

Protect exposed wiring from player foot traffic, c leaning crews, service personnel, etc. Use approved

conduit or wire channels to support cables. Network modular connectors don't include strain relief.

•

Keep cables away from heat, moisture and electromagnetic fields. (Avoid neon signs, fluorescent

fixtures, two-way radios, cordless telephones, power circuits, speaker wiring, etc.).

•

Universal RJ-45 modular plugs aren't keyed, numbered, or coded. Clearly mark cabinet network

connections. Otherwise, someone could confuse them with computer or telephone circuits.

•

The f actory supplies network cables with the cabinets. Thes e cables will reach the hub in network s of

four or fewer cabinets.

•

Use only Category 5, twisted pair cable.

•

If you want to monitor network activity, you can locate the hub remotely. You can use long cables, if

they satisfy these requirements: (1) Cables m ust not exceed a length of 328 feet or 100 meters. (2) Cables must be Category 3 (or higher), 100 ohm, unshielded, twisted pair, communications-grade wiring. (3) You must not use standard telephone cables.

GAME OPERATION

STARTING UP

Whenever you turn on the machine or restore power, the system executes boot ROM code. The boot ROM contains self-diagnostic tests. These tests autom atically verify and report the condition of the CPU and other hardware. If the hardware fails a test, the system displays an error message.

Having passed power-up tests, the system enters Attract Mode. Attract Mode consists of typical game scenes and sounds, alternating with high scores. Attract Mode continues until game play commences.

Players insert currency or tokens to start the gam e. Each player selects a truck and a cour se. Play begins after a countdown period. The game will progress until players quit or exhaust their playtime. At GameOver Mode, players may choose to begin again. If players choose not to continue, then the system returns to Attract Mode.

ARCADE COMPUTER

This game uses an Arcade Computer to control its functions. The Arcade Computer is a customized personal computer. Housing the Arcade Computer is a PC-like case. Inside, you’ll recognize the motherboard, plug-in cards, modular power supply, disk drives, etc. Despite these familiar features, Midway optimized this computer specifically for this game. The Arcade Computer design permits improved upgradability and service access without sacrificing ruggedness or reliability.

HEAD-TO-HEAD RACING

Networked cabinets offer players link ed, head-to-head r acing com petition. Each player begins the cours eselection process. A join-in message alerts subsequent players to the possibility of a linked race. If players don't begin their selection process before this message disappears, their races don't link. (Unlinked players compete in independent races, as usual.) Players may use the solo feature to decline a link.

If other players begin selection during the join-in message, the cabinets c ommunicate over the network. Each additional cabinet sends out its own packet containing a unique unit ID. In return, each cabinet receives data from active cabinets . A "waiting" message indicates that other players are still selec ting r ac e options. Eventually, the last player finishes selecting or the waiting period ends. At this point, all linked players see the start screen simultaneously.

Latecomers can't participate in an ongoing linked race. They can begin an independent race. The link automatically terminates when the game is over. Players can then set up another link.

MAINTENANCE

Units Units per Credit

Units per Bonus Minimum Units Credits to Start Credits to Continue Max Credits Coins per Bill

Cyber-currency. This adjustment assigns a number of “units” to each coin mechanism or bill acceptor. For instance, if a quarter buys 1 unit, then $1 buys 4 units. (See Coins per Bill.) You insert a coin into a 1-unit coin acceptor. The system, due to its programming, knows that your coin is worth one unit.

How many units equal one credit. (Units buy credit, the price of one game.) Units awarded when a player earns a bonus. Until this many units accumulate, the system awards no credits. Number of games a player must purchase to begin play. Number of games a player must purchase to resume play. Limits the number of credits that the game will accept. How many coins one bill is worth.

BASIC CUSTOM PRICING.

Custom pricing creates an imaginary currency exchange. In this currency exchange, the coins of the realm ar e “units.” T hink of units as a type of cyber-currency, useful only within the game software. By inserting coins, you purchase units.

Since units are only negotiable within game software, the system stores your units for you. When the system receives enough units, it buys a game for you. The price of a gam e is one “credit.” You can think of credits as a second form of cyber-currency.

Even though you’ve now bought one game, you may not be able to begin playing. In many pricing schemes, you must buy two or more cr edits to begin play. The idea here is som ething like a minimum order of goods at a store. That is , the operator can “shrink-wrap” two or more games in a package. You can’t play unless you buy the entire package.

1 / 25¢ COIN; 1 CREDIT TO START

•

In a simple, quarter pricing scheme, the player inserts one coin to buy one unit. The system exchanges that unit f or one credit. If CREDITS T O START contains the value one, then play commences. A dollar bill buys four units.

1 / 3 X 25¢; 2 CREDITS TO START.

•

Again, assuming quarter slots, here’s one way to implement 75¢ pricing… In this scheme, each coin that the player inserts buys one unit. The system ex changes three units for one credit. CREDITS TO START contains the value two. To play, the player must pay for two credits. In this scheme, a dollar buys four units.

Left Slot Units Validator Units Units / Credit Credits to Start Coins / Bill

2 / 1 COIN; 6 CREDITS TO START

•

Now let’s consider a more unusual pricing scheme. Here, the player can buy two units with one coin. The system exchanges each of these units for one credit. Notice that CREDITS TO START contains the value six. To play, the player must insert two m ore coins to pay for six credits. Also notice that if the player pays with a bill, the system throws in an extra unit.
