							2POWER TURN-ONThis game MUST BE PLUGGED INTO A PROPERLY GROUNDED OUTLET to PREVENT SHOCK HAZARD and toensure PROPER GAME OPERATION.  DO NOT use a cheater plug to defeat the ground pin on the line cord, and DONOT cut off the ground pin.  The line voltage must agree with that specified on the back of the cabinet or serious damage tothe machine could occur.  For low-line voltage applications (105v AC or 200v AC), refer to the power wiring diagram.1. With the game plugged into a properly grounded outlet, locate the POWER ON/OFF switch located at the top right-hand corner of the cabinet rear and switch it ON.  General illumination should come on and a scanning pattern shouldappear on the screen as the game sequences through ROM, RAM, and CMOS RAM data checks.2. If ROM and RAM tests are successful 0 is first indicated on the ROM Board 7-segment Diagnostic Display.  A fewseconds later the following message is indicated on the monitor:INITIAL TEST INDICATESALL SYSTEMS GO3.If a RAM error is detected, the 7-segment LED first displays a 1 to indicate a RAM failure.  Next, the bank number(1, 2, or 3) and finally the chip of the bank (1 to 8).  Then there is a pause and the LED display sequence is repeated.Next, another pause occurs and then the CRT displays a RAM ERROR XY where X is the bank number and Y is thechip of that bank.4.If a ROM error is detected, the 7-segment LED first displays a 2 to indicate that it is a ROM failure.  Next, the LEDdisplays two numbers which indicate the ROM chip number (01,02,03,...,12).  Then there is a pause and the LEDdisplay is repeated.  Next, another pause occurs and then the CRT displays a ROM ERROR X where X indicates theROM number.5.If the CRT display shows any RAM or ROM errors, use the above description to identify the faulty chip and then turnpower off and replace the chip.6. If there is no CRT display at power-up:a.Open the upper back door to the game.b.Disengage the latch and open the lower back door.c.Depress the Reset push-button on the CPU/Video board and observe the 7-segment LED display on the ROMboard to identify any faulty chip.d.After identifying the chip, remove power to the game and replace the faulty chip.e.As only one chip at a time is indicated by the testing system, repeat steps c & d until there is a CRT display.7.Extensive CMOS RAM data integrity checks are performed.  With OPEN COIN DOOR displayed, check that thebatteries on the CPU/Video Board are seated in the battery clips, open the coin door, and then turn power OFF andON.  A display of FACTORY SETTINGS RESTORED should appear.8.Depress ADVANCE and turn the power OFF and ON to get to game over.NOTE:A detailed explanation of the CMOS RAM data integritychecks and system recovery is provided in appendix A.

Rescue humanoids and pick them up to collect bonus.  Picking up the first humanoidscores 500 points, the second 1000, the third 1500, and all subsequent score 2000.Going through the STARGATE warps the player ship to an area where a humanoid requires rescue.  Passing through theSTARGATE forward while carrying *4 humanoids, warps the player ship to an advanced wave and scores appropriatehumanoid bonuses.  Going through backwards inhibits the warp. 
						

							4BOOKKEEPING AND EVALUATION TOTALS1.In Game Over mode, open the cashbox and depress the cashbox advance switch.  The advance switch located on thecoin door can also be used.  The CRT should indicate all bookkeeping and evaluation totals.  If so, go to step 3, if theCRT display comes up in the ROM test display perform step 2.2.Continue to depress the cashbox advance switch, stepping the game through test programs for ROMs, RAMs, CMOSRAMs, Color RAMs, Sounds, Switches, and then CRT Test Patterns, of which there are five.  The fifth test pattern is acolor bar pattern and directly precedes the CRT display of the bookkeeping and evaluation totals.3.The bookkeeping and evaluation totals appear on the display as in Figure 1.Clearing Bookkeeping Totals1.Depress ADVANCE to display Game Adjustments, page 1.2.Hold joystick down to display Game Adjustments, page 2.3.Operate joystick to position cursor on CLEAR BOOKKEEPING TOTALS.4.Depress FIRE.5.

							5GAME ADJUSTMENTS (Figures 2 and 3)In the Game Over mode open the coin door and depress the coin door advance switch twice to cause a CRT display asshown in Figure 2.To select and then set functions to the desired values, use the UP-DOWN control lever to select the function that is to bechanged and then, making sure the coin door is open, use the THRUST control to reduce, or the FIRE control to increase thevalue of the selected function.  To alternate between adjustments on pages 1 and 2, use the UP-DOWN control.Extra ships, smart bombs, and inviso time are earned as the score obtained by a player exceeds the listed value for thisfunction.  If this function is set to the recommended value of 10,000 points, with a score of 10,000 points a player willreceive one more ship to play with.  At a score of 20,000 points another ship will be earned, and so on.  If this function is setto 0, its lowest setting, no extra ships are ever awarded.  This function can be set to any 1,000 point increment from 0 to50,000 points.The basic number of ships awarded for a 1 credit game can be set anywhere from 1 to 20.  The recommended number ofships for a 1 credit game is 3.The basic number of ships awarded for a 2 credit game can be set anywhere from 0 (no 2 credit games) to 50.  Therecommended number of ships for a 2 credit game is 7.Pricing of the game is selected with standard settings or with custom settings as shown in Tables 1 & 2.  Table 1 lists somecommon pricing schemes with respect to the coin mechanism to be used and directs the reader to the proper entry in Table2, which shows what the CRT display should look like to accomplish the desired pricing.For standard settings you need change only the PRICING SELECTION.  For custom settings, first set PRICINGSELECTION to zero and then set the remaining values according to Table 2.Figure 2.

							6Figure 3.  Game Adjustments, Page 2Free play can be set to either YES or NO.The master difficulty control is pre-programmed for 4 levels of difficulty and can be custom programmed for 1 as desired.The recommended setting of the master difficulty control is 3.  If customized difficulty is desired, set the master control to 0and with the use of the UP-DOWN control and THRUST and FIRE controls, set each of the 5 variables as desired.Initial difficulty is the level of play difficulty for the first attack wave of the game and can be set anywhere between 0 (easy)and 30 (most difficult).Maximum difficulty is the level of difficulty at which difficulty increases between attack waves cease.  This can be setanywhere from 0 (very easy) to 99 (very difficult).The last three adjustments; first wave of accelerated difficulty, last wave of accelerated difficulty, and difficulty accelerationrate; are all inter-related.  The first wave of accelerated difficulty is the point at which the standard difficulty increase ratebetween attack waves is first stepped up.  This can be set to any wave from 1 to 20.  The last wave of accelerated difficultyis the point at which the stepped up difficulty increase rate is decreased to the standard difficulty increase rate (exactlythe same as it was before it was stepped up).  This can be set to any wave from 1 to 99.  The difficulty acceleration rate canbe adjusted anywhere from 1 to 10.  When any of these functions are set to 0, there is no accelerated difficulty.The amount of INVISO time allowed per ship is recommended to be 1 second but can be varied from 0.5 to 2 seconds intenth-second increments.The number of men needed to WARP a ship anywhere is recommended as 4, but can be varied from 1 to 9.  The last wavewhere any WARPING of a ship would be allowed can be set anywhere from 1 to 99, but is recommended as 15.MASTER DIFFICULTY CONTROL    3RECOMMENDED   INITIAL DIFFICULTY    5MODERATE   MAXIMUM DIFFICULTY  15MODERATE   1ST WAVE OF ACCELERATED DIFFICULTY    0   LAST WAVE OF ACCELERATED DIFFICULTY    0   DIFFICULTY ACCELERATION RATE    0MODERATEINVISO TIME PER SHIP  10RECOMMENDEDMEN NEEDED TO WARP    4RECOMMENDEDLAST WAVE WARP ALLOWED  15RECOMMENDEDLETTERS FOR HIGHEST SCORE NAME  20RECOMMENDEDRESTORE FACTORY SETTINGS NOCLEAR BOOKKEEPING TOTALS NORESET HIGH SCORE TABLE NOAUTO CYCLE NOSET ATTRACT MODE MESSAGE NOSET HIGHEST SCORE NAME NO
