I am not going to explain these cause they are self- explanatory Loading Instructions Amiga Start your Amiga with Kickstart 1.1 or higher, the eject the disk and insert Silent Service. It will load automatically. Leave the disk in the drive during the game. You can use either the mouse (port 1) or a joystick (port 2) to play the game. Atari ST If your computer already has TOS in ROM, simply place the Silent Servive disk in your computer and turn it on. Leave the disk in the drive during play. If you have an early version ST with no ROM TOS chips, insert your Atari TOS disk in the drive first, then turn on the computer. When the desktop appears, remove the TOS disk and insert the Silent Service disk. Then press the ESC key to display the contents of the disk. When the contents appear, use the left button to double-click on the folder called AUTO. The AUTO folder will open to show a program called SERVICE.PRG, double-click on this program and the game will start. IBM PC or TANDY 1000 NOTE:Your IBM PC must have a color graphics card to play this game. You may use either keyboard or joystick to play. Place the game disk in your drive and turn on the computer. The disk will boot automatically. Leave the disk in during play. OPTIONS Upon loading, you will be allowed to select the senario, options, and skill factors you wish to use. Scenarios There are three types of scenarios. "Torpedoe/Gun Practice" places you outside the American base at Midway Island. Four old cargo ships are anchored there as torpedoe and gunnery practice targets. The second set of scenarios: "Convoy Actions", recreate various actual submarine attacks on a convoy. "War Patrols", allow you to command an entire patrol, beginning at the submarine bases at Midway, Brisbane, or Fremantle; continuing through a number of convoy actions; and concluding with a return to base. Skill Levels You may select from one of four skill levels: "MIDSHIPMAN", "LIEUTENANT", "COMMANDER", or "CAPTAIN". The skill level affects the accuracy of torpedo runs, damage sustained from depth charges, the skill of enemy lookouts and sonar operators, as well as other factors. Reality Levels In addition, you may customize the similation with various "reality levels". Each level introduces an element which makes the similation both more realistic and more diffilcult. To select the reality levels, use the joystick to mve the flashing asterisk and press the trigger to toggle the YES/NO indicator or use the left button on the mouse to toggle the levels on and off. 1) Limited Visibility If this level is selected enemy ships which are beyond radar/sonar range will not appear on the map displays. Enemy ships which were detected but have moved out of range will blink slowly at their last known position. If this level is not selected, all enemy ships will appear on the map displays requardless of their range or location. 2) Convoy Zig-Zags If this level is selected enemy convoys will "zig-zag"(change course) at regular intervals. If this level is not selected, cargo ships will steam straight ahead unless they are attacked by torpedoes or encounter land masses. 3) Dud Torpedoes If this level is selected some of your torpedoes may be duds, especially during the years 1942-1943. Dud torpedoes may hit the enemy but will not explode, only the splash will be seen. 4) Port Repairs Only If this level is selected repairs will no longer be accomplished automatically while in battle or on patrol. Once an item of major equipment is damaged, it may not be repaired. 5) Expert Destroyers If this level is selected certain enemy convoys will be escorted by 'expert' destroyers. These escorts are more persistant and have better trained sonar operators. 6) Convoy Search If this is selected convoys will not always appear within radar range. You will need to search them out. Far off convoys are best sighted by performing a 360 degree periscope/binocular sweep of the horizon. 7) Angle-on-the-Bow Input If this level is selected the computer will no longer calculate the 'Angle-on-the-Bow' for torpedo shots. You must enter the angle yourself based on periscope observations. Be sure you understand the workings of the Torpedo Data Computer before attempting this level. Recommended for experienced players only. Instruments and Gauges This screen displays vital status information. The straight up position for all gauges represents a zero value, with increasing values in the clockwise direction. The primary instruments and gauges are: a) BATTERY LEVEL- Shows how much electicity is remaining. The battery is used for submerged running and is gradually recharged while on the surface so don't be cruising all the time underwater for if it runs out, you will be unable to move save for up and down. b) BATTERY CHARGE LIGHT- indicates the battery is being charged c) BATTERY IN USE LIGHT- indicates the battery is being drained. d) SPEED- indicates speed of sub. Max suface speed is 20 knots and max speed underwater is 10. e) DEPTH- indicates current depth. Periscope depth is 44 feet or less. f) PERISCOPE INDICATOR- guess what this does?? g) TORPEDO READY INDICATOR- shows how many are ready for firing. Green indicates ready and red means not ready. Reloading is done automatically and requires about 10 game minutes per tube. h) FUEL LEVELS- Another puzzling instrument. See if you can figure it out! i) DEPTH UNDER THE KEEL- a gauge showing the depth from your sub to the ocean floor. When this gauge reads zero you will run aground. Max reading is 500 feet. j) WATER TEMPERATURE- shows temp of water outside sub. A blue dial hand indicates that the sub is below a thermal gradient layer. k) CHRISTMAS TREE- light indicating the status of all hull openings. Green means open. These are closed automatically when you dive. l) COMPASS- ???/ M) THROTTLE- 0-4 setings. Shows speed of craft. n) CLOCK- shows time of day o) DIVE BUBBLE- a horizontal tube showing whether the sub is diving or surfacing. Damage Reports Battle Station This screen indicates the nature of any damage to the submarine. Damage may be caused by depth charge attacks or enemy gunfire. Types of damage include: 1) Bow/Aft torpedo damage: these torpedo doors have been damaged. The torpedoes will not fire. 2) Periscope damage: the periscope housing has been damaged. It cannot be lowered or raised. 3) Dive Plane Damage: the bow and stern dive planes have been damaged. The sub will only dive or surface at half its normal rate. 4) Fuel Leaking: the external fuel tank are leaking. Fuel will be consumed at twice the normal rate. In addition, fuel rising to the surface will make the sub easier to detect by enemy destroyers. 5) Engine damage: the main diesel engines are damaged. Speeds are reduced by half. 6) Machinery Damage: internal pumps and engines are damaged. The extra noise will make the enemy's sonar tracking easier. 7) Battery Damage: batteries are used at twice the normal rate. If the "PORT REPAIRS ONLY" reality level is not selected, repairs are attempted by the crew automatically. If your sub is taking on water, the leakage rate is indicated in gallons per second (GPS). Leakage will often cause your sub to decend, although the dive planes may be able to counter-act the dive. This information is provided in the top right hand side of the Damage Reports Screen.
